The AQUALAB 4TE water activity meter can measure water activity (aw) in 5 minutes or less with ±0.003 accuracy. AQUALAB instruments are the fastest, most precise water activity meters available.
Get lab-quality water activity (aw) measurements no matter what step of your process, thanks to the 4TE's rugged hardware and internal temperature control. At the line, receiving dock, processing plant, storage facility, or even outside the quality control lab - anywhere you need to test and verify the safety and quality of your products.
Easy maintenance
AQUALAB 4TE lets you spot contamination quickly with the flip of the lid. The sample chamber can be opened for any easy-to-clean maintenance.
Starter set
All verified AQUALAB 4TE’s are shipped with a calibration certificate, power cord, USB A to USB B cable, 50 disposable sample cups, an AQUALAB cleaning kit, and two vials of each of the verification solutions.
Built for abuse
Take readings in the harshest conditions – on the line, in receiving or shipping areas. Aqualab devices don’t need a pristine lab to consistently deliver quality data.
Long life, good investment
We stand behind our devices for decades. You’ll never be left without support. No pushy upgrade schemes or shady long-term maintenance contracts, just long-term benefits.
In the lead for 40 years
Since our founding in 1983, we’ve stayed laser-focused on moisture management science – and built the industry’s largest body of expertise on the topic.
Any sample, always accurate
92% of the top 100 food companies use Aqualab devices for moisture analysis. Throughout formulation, production and QA — from raw ingredients to final product and anything between.
Delivery time: usually ships within 2 business days
Research into Stevia and how best to use it gives Arboreal a competitive advantage in the alternative sweeteners industry.
Arkopharma is Europe’s leading provider of plant-based supplements. Accurate water activity measurements help them ensure that doesn’t change.
Tillamook was born in a backyard smokehouse in the 1960s. Even with extreme growth, TCS has remained committed to producing the most authentic beef jerky on the market.
