AQUALAB 4TE
Accurate and reliable water activity meter
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.
for readings
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.
aw accuracy
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, 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.

Water activity is a thermodynamic measure of the energy of water in a product. Why should your company learn how to measure water activity? It is directly related to the microbial susceptibility of food products. It also has direct relationships with many of the reactions that end shelf life in foods.
