A&D EK-30KLK Specific Gravity & SSD Balance - 30 kg x 0.1 g
The A&D EK-30KLK is a high-capacity precision bench scale designed for Canadian materials testing laboratories that need 30 kg capacity with 0.1 g readability across the full weighing range.
With a large stainless steel pan, standard underhook weighing capability, RS-232C communication, and a 2-year warranty, the EK-30KLK is a strong fit for laboratories working with aggregate SSD testing, specific gravity, absorption, soils, concrete, asphalt QC, geotechnical testing, and construction materials workflows.
Unlike lower-resolution high-capacity scales, the EK-30KLK maintains fine 0.1 g readability up to 30 kg, making it especially useful when large samples still require detailed mass measurement.
Built for Canadian Materials Testing Labs
- Aggregate and concrete SSD testing
- Specific gravity and absorption workflows
- Soils and geotechnical testing
- Asphalt quality control and compacted specimen testing
- Construction materials laboratories
- Education, R&D, training, and method demonstration labs
- Provincial, municipal, contractor, and third-party testing laboratories

- Optional battery operation: The HC-02i rechargeable battery option supports field trailer, mobile lab, and flexible bench use.
- Canadian purchasing support: Supplied by Cambridge Environmental Products with CAD pricing, Canadian support, and a 2-year warranty.
Built for ASTM, AASHTO, and CSA Materials Testing Workflows
The A&D EK-30KLK is well suited for Canadian laboratories that need a balance for specific gravity, SSD, absorption, density, aggregate, soil, concrete, and asphalt QC workflows.
This model meets the apparatus requirements of AASHTO M231, Class G2 and supports workflows commonly associated with CSA A23.2-12A, ASTM C127, ASTM C128, ASTM D854, ASTM D2726, AASHTO T84, AASHTO T85, AASHTO T100, and AASHTO T166.
In practical terms, this is the balance to consider when your lab needs 30 kg capacity, 0.1 g readability, underhook weighing, and documentation support for construction materials testing.
Test methods govern procedure, sample handling, tolerances, calibration, and documentation requirements. Buyers should confirm that the balance, accessories, calibration, and complete weighing setup meet the specific method and internal QA/QC requirements being followed.
Calibration, Documentation, and Canadian Lab Support
If your lab requires calibration documentation, traceability records, printer output, or a complete specific gravity weighing setup, Cambridge Environmental Products can help quote the balance, calibration weight, printer, underhook basket, and available documentation options together before you order.

Technical Questions About the A&D EK-30KLK
What is the difference between the A&D EK-30KL and EK-30KLK?
The EK-30KL is a smart-range model with 0.1 g readability in the lower range and 1 g readability at higher loads. The EK-30KLK provides 30 kg capacity with 0.1 g readability across the full weighing range, making it the better choice for large aggregate SSD, specific gravity, soils, asphalt, and materials testing workflows where fine readability is required at higher sample weights.
Why does full-range 0.1 g readability matter for materials testing?
Full-range 0.1 g readability allows labs to weigh larger samples while still maintaining fine resolution. This is important for SSD, absorption, density, and specific gravity workflows where small mass differences can affect calculated results.
Is the EK-30KLK suitable for ASTM and AASHTO aggregate testing?
Yes. The EK-30KLK is positioned for aggregate, concrete, soils, geotechnical, and asphalt QC workflows. It meets the apparatus requirements of AASHTO M231, Class G2 and supports workflows commonly associated with ASTM C127, ASTM C128, ASTM D854, ASTM D2726, AASHTO T84, AASHTO T85, AASHTO T100, and AASHTO T166.
Is the EK-30KLK suitable for CSA A23.2-12A workflows?
Yes. The EK-30KLK supports workflows commonly associated with CSA A23.2-12A for density and absorption testing of fine aggregate. Users should confirm their complete weighing setup, accessories, calibration, and documentation meet their internal method requirements.
Does the EK-30KLK include underhook weighing?
Yes. The EK-30KLK includes standard underhook weighing capability for below-balance weighing setups. For specific gravity and SSD testing, labs will typically also need a suitable suspension setup or basket, such as the CEP-226 Specific Gravity Basket.
Can the EK-30KLK provide records for QA/QC documentation?
Yes. The EK-30KLK includes RS-232C communication for data output to a compatible printer, PC, or LIMS-style setup. The AD-8127 printer can be used when printed weighing records or GLP-style documentation are required.
Can calibration documentation be supplied with the EK-30KLK?
Calibration requirements vary by lab, quality system, and test method. Cambridge Environmental Products can help quote the EK-30KLK with the required calibration weight, printer, specific gravity accessories, and available calibration documentation options for Canadian laboratory buyers.
Do I need extra hardware for underhook weighing?
The EK-30KLK includes standard underhook weighing capability, but users will typically require a suitable suspension setup, tank, or basket depending on the test method and workflow.
Is the pan large enough for SSD and aggregate testing setups?
Yes. The EK-30KLK has a 300 x 210 mm / 11.81 x 8.27 in stainless steel pan, providing practical working space for common containers, samples, and materials testing setups.
Can the EK-30KLK be used in a field trailer?
Yes. With the optional HC-02i rechargeable battery pack, the EK-30KLK can be used in mobile or field trailer setups within its rated operating temperature and humidity range.
What calibration weight does the EK-30KLK require?
The EK-30KLK requires a 15 kg calibration weight. Regular calibration helps support traceability, QA/QC records, and reliable materials testing results.
