Product Details

AQUALAB 4TE Accurate and reliable water activity meter Description:

Speed & 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 measurements no matter what step of your process: at the line, receiving dock, processing plant, storage facility—even outside the QC lab. Anywhere you need to test and verify the safety and quality of your products.

Internal temperature control lets you set a measuring temperature between 15 and 50 °C and use the instrument anywhere—even outside the quality control lab.

How it works

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 4TE extremely accurate, so you can have complete confidence in your 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
