Accelerate Commercial Electrical Diagnostics with the Bosch PRO GFM1000-15

The Bosch PRO GFM1000-15 Professional Fork Meter is a revolutionary diagnostic solution engineered to accelerate system maintenance for electricians, facility technicians, and HVAC contractors. Featuring an open-jaw design, this powerful electrical tester enables non-invasive AC current measurements up to 200 Amps directly over conductors without breaking active circuits. Seamlessly integrated with high-performance True RMS technology, it accurately interprets distorted waveforms on complex commercial equipment, allowing for swift and reliable fault-finding in tight, high-density distribution environments.

Built for survival on demanding jobsites, the GFM1000-15 features a rubber-reinforced housing that is field-tested to withstand accidental drops from up to 6 feet and is protected by an IP54 dust and splash resistance rating. This all-in-one instrument records AC/DC voltages up to 1000 Volts and integrates specialized features like low-input impedance (LoZ V) to automatically eliminate phantom ghost voltages. Complete with a built-in non-contact voltage (NCV) detector, an integrated LED panel flashlight, and an uncompromised CAT IV 600V / CAT III 1000V certified safety rating, it delivers ultimate field confidence and reliable one-handed usability.

Key Features

  • Rapid Non-Invasive Diagnostics: Open-fork jaw design captures fast AC current measurements without lead connections or circuit interruptions.
  • Advanced True RMS Accuracy: Engineered to provide highly reliable, precise electrical readings on non-sinusoidal waveforms and active variable loads.
  • LoZ ghost Voltage Elimination: Low input impedance mode filters out misleading ghost voltage readings across adjacent live wiring runs.
  • Rugged Heavy-Duty Architecture: Rubber-molded ergonomic grip resists jobsite abrasion, drop-tested up to 6 feet with an IP54 weatherproofing rating.
  • Dual-Source Power Versatility: Operates universally on standard AA batteries or a professional 3.7V Lithium-Ion rechargeable pack for diminished downtime.
  • Integrated Safety NCV Sensor: Built-in non-contact voltage tester provides fast, audio-visual proximity checks before managing exposed wires.
  • High-Visibility Inverted Screen: Crystal-clear, high-contrast inverted LCD ensures immediate visibility inside unlit industrial enclosures or basements.
  • Premium Safety Compliance: Certified to elite CAT IV 600V and CAT III 1000V safety classes with integrated protective power cuts when battery doors open.

What's Included

  • (1) Bosch PRO GFM1000-15 True RMS Fork Meter
  • (1) Set of High-Quality Flexible Silicone Test Leads
  • (2) Standard AA Batteries

Pro-Tip: When troubleshooting confusing modern lighting ballast setups or commercial HVAC controls, toggle the GFM1000-15 to LoZ mode. This pulls down stray capacitive ghost voltage created by parallel wire runs, confirming instantly whether you are tracking down an actual electrical fault or just a harmless induced field signal.

Great Mouse
I normally use the Logitech M325c. I've gone through dozens over the years. It works very well, but they seem to wear out fast; the wheel scroll is what fails. I decided to give the Amazon Basics a try. So far, it looks, feels, and functions the same as the Ltech; it doesn't have the fun colors, but if it holds up longer than a year, it's a fair tradeoff. I will revise this review if things change in the future, but as of now, I would recommend the Amazon Basics and will replace the other Ltech's when the time comes.

High Quality and Operability - Great!
Great mouse! Not only good, but feels and operates as well as, or better than a Microsoft mouse, and a lot more reasonable! Comes with AAA batteries, the USB transceiver is stored inside the battery compartment (good when packing and traveling), and a white support strap lays down below the installed batteries so that it is easier to remove them when its time to change the battery. Be sure to go into Control Panel/Mouse and make any click-speed or mouse movement adjustments to your liking. I plan on buying another one of these for my second HP laptop. The USB transceiver is immediately responsive and you will see a red laser at the bottom of the mouse.

Works Perfect, No Installation Needed, Perfect Size, and Wonderful Price!
Several months ago when the keys on my laptop mouse pad started to go out, I was really irritated because I have gotten so used to using the mouse pad that I was worried that I wouldn't be able to work as efficiently using a wireless mouse. I knew that it would only be a few days before the keys got to the point that I wouldn't be able to use them and started looking on Amazon for a wireless mouse that I might possibly be able to stand using on a daily basis. I spotted the AmazonBasics Wireless Mouse and thought that it wouldn't be that great because it was way cheaper than most of the other wireless ones that I could find. I went ahead and placed my order because I needed something and thought that if it didn't work that well, I wouldn't be out of that much money. When it arrived, I was happy to see that it was a tad bit smaller than other ones that I have used with desktops in the past since I have small hands. I opened the package, popped in some batteries, plugged the nano receiver into my USB slot, and it was working instantly. I thought that it would take some time to install ( I did not read much on it when I purchased it honestly, I just needed one quick!), but was SO happy to see that it needed nothing to be installed. I have been using this wireless mouse for about a year and half now and I have recommended it to SO many people who were looking for one. I work at home on my laptop 7 days a week and anywhere between 12 - 18 hours a day. I only have to change the batteries about once every two months (sometimes it will go a little longer and sometimes a little bit less - not sure on why though). This mouse has worked flawlessly since the day of purchase and I was SO wrong to think that because it was cheaper than the others that it wouldn't work as well. There has never been a time where it disconnected from the computer or that there was any issue using it. A few times when it has needed the batteries changed and I wait a few days, there is a tiny lag - but that is all my fault. The AmazonBasics Wireless Mouse has a little red indicator light that lets you know when the batteries are getting low and need to be changed. I like that feature so that I'm always aware of when they need to be changed. Since I travel a lot, this mouse is great because it doesn't take up a lot of space in the laptop bag. I also never have to worry about losing the nano receiver because once you remove the little door to the battery area, there is actually a space that the nano receiver clicks into making it perfect for travel. If you are in the market for a great wireless mouse, I would recommend the AmazonBasics Wireless Mouse because it has been through over a year of my all day, everyday use and still works just like the day that I purchased it!

It works and is well priced.
This mouse works as well as much higher-priced brand-name items. It fits well in the hand. The durability is very good. Considering the price compared to other brand names, this is a very good value.

Solid Everyday Mouse with a Few Comfort Trade-Offs
I’ve been using this Amazon Basics 2.4 GHz wireless optical mouse as a simple, no-frills option, and overall it does exactly what it’s supposed to do. Setup was instant with the USB nano receiver, tracking is accurate, and the wireless connection has been reliable with no dropouts or lag during daily use. It’s lightweight and works well for general browsing and office tasks. Where it falls a bit short for me is ergonomics. Compared to my Logitech mouse, this one doesn’t feel quite as natural or contoured in the hand during longer sessions. It’s by no means uncomfortable, just not as refined in terms of hand fit. That said, for the price and simplicity, it’s a dependable mouse that gets the job done. A solid choice if you want something basic and reliable.
