Experience the speed, precision, and reliability that set the standard in water activity (aw) measurement. Discover the AQUALAB 4TE water activity meter—the trusted instrument that revolutionized moisture management in industries worldwide.
Speed and accuracy.
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.
Measure anywhere
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.
The secret to the 4TE’s speed and accuracy is in its unique chilled mirror dew point sensor. The dew point sensor is a primary measure of water activity. Unlike other water activity sensors, the dew point sensor measures water activity (aw) directly, not secondary parameters correlated with water activity. This makes the AQUALAB 4TE extremely accurate, so you can have complete confidence in your water activity sample readings.
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.
