AQUALAB® 4TE Stand Alone Water Activity Meter with Temperature Control

Measure water activity (aw) in 5 minutes or less (average read time: 2.5 minutes) with ±0.003 aw accuracy. Instruments are the fastest, most precise water activity meters available. Use to get lab-quality measurements at the line, receiving dock, processing plant, storage facility—anywhere you need to test and verify the safety and quality of your products and ingredients. Internal temperature control lets you set a measuring temperature between 15° and 50°C, and allows you to use the instrument anywhere, even outside the QC lab.

How It Works:

The secret to 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 actually measures water activity (aw), not some secondary parameter merely correlated with water activity. This makes this meter extremely accurate, so you can have complete confidence in your sample readings.

Easy To Clean:

The sample chamber lid flips up so contamination in the sample chamber is quick to spot and easy to clean.

Secure Food Safety Data:

Stores time, date, and user information with every measurement and calibration, and can store up to 10,000 secure data points. Administrative functions can be set to control access to data. Designate up to 25 unique users and passwords. Use the RS-232 serial data port to download or print data for statistical analysis and to maintain compliance records and archives.
