Particle counter for air quality measurements
Nowadays, the fine particulate burden in the air and its health effects are an essential part of public discussions. But what is it that makes fine particulates so dangerous? Fundamentally, a distinction is made between the two particle fractions PM10 and PM2.5.
PM10 includes all particles with a maximum diameter of 10 µm, and PM2.5 means all particles with a diameter of less than 2.5 µm. These particles are invisible to the naked eye. As small as they are – especially the particles of the size PM2.5 – they can reach the pulmonary alveoli. Yet more minute particles of less than 1 µm can even reach blood vessels.
In our everyday life, we are exposed to countless potential sources of fine particulates. No matter whether you are living or working next to an extremely busy road or near an industrial area – it is likely that the fine particulate burden of your breathing air is increased. In rooms and buildings where many people are situated, the CO₂content often increases above average.
But also ordinary things and tasks such as cooking, vacuuming, candle or tobacco smoke – just like the emissions from heat sources (e.g. stoves and fireplaces) – can have a direct negative effect on the indoor climate and consequently the well-being. For an increased concentration of fine particulates and CO2 in the air can not only affect the overall well-being, but also be responsible for difficulties in concentrating and insomnia as well as for various allergic reactions. On a long-term basis, the exposure to fine particulates increases the risk of developing cardiovascular and respiratory diseases, even pulmonary cancer.
Using the convenient particle measuring device BQ30 you can always keep an eye on the fine particulate, CO₂, air temperature and humidity values. This way, you can improve the room climate through fresh air supply or the effective use of air cleaners, humidifiers or dehumidifiers whenever required.
The compact, long-term air quality monitor BQ30 allows you to simultaneously detect both critical fine particulate concentrations and CO2 emissions in the air in a reliable and precise way. Additionally, the convenient all-round measuring device also measures the air temperature and humidity level.
Mobile laser particle counters are the ideal solution for monitoring, securing and assessing the air quality.
The large 3" colour LCD display of the BQ30 allows you to simultaneously read the particle mass concentration in the air, the CO2 content, the air temperature, the relative humidity level as well as the date, the current time and the battery status. Moreover, a coloured bargraph indicator reveals at one glance whether the particle burden is in the "green" range.
Displaying different shades of yellow, the air quality monitor BQ30 visually indicates that the measured values for PM10/PM2.5 particles are in the "normal" range. A red display corresponds to a "moderate" contamination. It is also possible to set individual thresholds based on the predefined limit values.
If the display colour changes to violet or purple, the predefined limit values for the particle quantity have been clearly exceeded. To improve the poor air quality in the short term, proper ventilation may be advisable. Equally, the values for the CO2 content in the air are also separately displayed with the corresponding colour gradations.
Automatic baseline calibration
The expected CO2 fresh air value is about 400 ppm (0.04 %vol) nowadays. The device assumes this value to be the lowest limit value (baseline). Over several days, a special algorithm now permanently checks the lowest CO2 value measured of the sensor over a preconfigured time interval and slowly corrects every long-term drift determined by comparison with the expected fresh air value of 400 ppm (or 0.04%vol) CO2. In normal indoor applications, the carbon dioxide level usually decreases almost to outdoor air level at some point during one week. By recording the values over a period of 8 days and then comparing the lowest value to the 400 pm point, the device determines whether or not it needs to adjust the zero point. This takes place fully automatically. The algorithm therefore makes use of the fact that the CO2 content in buildings and rooms regularly stabilises at a minimum for a certain period of time when they are not occupied. In rooms that are continuously occupied or where there is a constantly increased CO2 concentration (e.g. in greenhouses), this principle of automatic balancing therefore does not work.
Keep an eye on the house dust, fine particulate, soot and pollen concentration
The user-friendly, mobile air quality monitor detects and quantifies the mass concentrations of various fine particulates. For this purpose, the measuring device's laser technology easily captures even the smallest air contaminations of sizes PM2.5 and PM10 in micrograms per cubic metre.
Thanks to the adjustable time intervals, the BQ30 also allows for effective long-term control of the particle burden. Up to 5,000 data records can be saved, including both the PM concentrations and the date of detection. If desired, this large variety of data can be conveniently displayed as curve characteristics on the large 3" colour display.
With respect to the mass concentration of particle size PM2.5 you can define limit values preset in the BQ30 which, when exceeded, trigger an acoustic alarm signal. Additionally, a six-level colour display indicating the respective alarm levels helps you to quickly assess the current state of the particle concentration ranging between good and highly critical.
All-round measuring device monitoring your feel-good climate
Furthermore, the handy all-round measuring device simultaneously also detects other room climate parameters relevant to health, such as the CO₂burden in ppm, the air temperature ranging from -20 to 70 °C as well as the humidity level of 0 to 100 % RH. The measured PM10 and CO₂ values are displayed on an automatically alternating indication. Another three-colour indicator completes the user-friendly visualization of these two parameters in particular, indicating the air quality on a scale from good to poor.
Its precise measurement results, wireless and untiring battery operation, low weight and compact dimensions make the air quality monitor BQ30 the perfect companion for wherever a detection of a potentially harmful fine particulate and CO₂pollution is required.

Great dog chew lasts a while, enjoyed by most every dog
These bones are great for a few small, yet significant reasons. Bottom line up front: They're great and a dog owner would be well served to pick up one or two of these as a long term chew toy your dog is almost sure to love.
1) The first being the odd shape of the bones. The shape enables the dog to pick up the bones with ease rather than some of the more flat bones or chews which can lead to a struggle and frustration. The three prongs and the elevated middle portion alleviate this concern.
2) These bones aren't ground material shaped into a bone shape, they are tough, plastic-like substances. They have a very subtle aroma of the flavor they are supposed to be (bacon, chicken, etc) but are completely safe for the dogs to munch on. The best part of the bones being this substance is that they last quite a long time.
3) The bones are lightweight and won't hurt you if you stub your toe as you walk around the house barefoot.
4) Dogs seem to love them. Only the most picky or reclusive dogs will ignore these bones.

Good size, lasts a long time
Dog likes these. She has her moments when this is only chew toy she wants, and spends days gnawing on it. She likes these bacon and chicken flavors. I like the fact that there is no squeak. This is a good size for full size Aussie, and I also like that she doesn’t “throw” these at me, she lays on the couch or floor and chews. They help to keep her teeth clean from plaque and tartar, so to me they are very functional. This is 4th or 5th buy again, so I wouldn’t buy again if she didn’t like. It does take a while for her to chew to point of needing new, since I keep variety of chew toys for her.

Awesome!
**update: we have had this toy for over a year! I have found one other con. Once chewed if you step on it you will immediately drop to the floor in agonizing all encompassing pain or (my personal favorite) say every dirty curse word you have ever heard while clutching your destroyed instep. BUT even though this chewed bone is the demon child of a LEGO and a race car to step on my dogs still love it, still chew it and we haven’t had to replace it yet!
I have an insane chewer where toys usually last us less than 24 hours. It has become almost impossible for us to keep up with toys because of how expensive it has become. This toy is not only insanely durable but she has not left it alone for the 3 days we’ve had it.
I was concerned that being “chicken flavored” would mean stinky or sticky and I was very pleasantly surprised that it was neither! It doesn’t leave a stain once chewed, it doesn’t smell, and it doesn’t have a weird coating on it.
The only con so far is that due to it being so durable and hard it makes a loud noise when dropped on the tile or hardwood which made her nervous toward it at first but now that she’s started working on it she could care less about the noise. Super happy with this purchase and will 100% buy more in various sizes for our other pups.

Quieter than most toys and my dog loves them
Color: Football, Size: One-Size
These footballs have saved my life. I think I’ve bought close to 10 at this point? And toys primarily living outside in Texas heat is the only reason I’ve had to buy so many. In general, they are pretty durable but will get cracked if you leave them in the sun.
I have a German Shepherd who absolutely loves playing in the backyard but also takes his responsibilities as a guard dog very seriously so he barks a LOT while he is out there and unfortunately we live in the suburbs so I’m constantly bringing him inside that way he isn’t bothering the neighbors.
That is, until I got this football. The grunts are pretty quiet which is a win in my book because my dog communicates by way of squeak toy. You might think I’m joking but if I have guests over and we are having a conversation, he comes in the room and squeaks his toys violently to participate in the discussion.
For that reason, it takes me an hour to pick out a new toy at the store because I stand in the aisle squeaking every single once until I find one I think I can handle listening to 24/7. If you’re reading this review, you probably know that at a certain point, the squeaks can become unbearable. If that’s why you’re looking at this toy, you don’t have to read any further. Just buy it, you won’t regret it. That is reason enough for me to rate this 5 stars.
But the story doesn’t end there. What I did not foresee was him also using this wonderful grunting football to communicate with the neighbors. Now instead of barking outside, he grabs one of these footballs and squeaks it for all he’s worth while bucking around in circles like a bull. He still does it after having broken the noise maker in the toys. He just loves them so much.
Can I guarantee your dog will also take to squeaking this toy over barking? No. I didn’t do anything special to get him to do that, and I doubt I could train another dog to do so. Regardless, this toy has single handedly solved a lot of my dogs endearing but somewhat annoying habits in ways I could not have anticipated so maybe it’ll work for you too.
