Fast—water activity readings in 5 minutes or less. ENSURE THE SAFETY AND QUALITY OF YOUR PRODUCTS se AquaLab to get lab quality water activity measurements at the line, receiving dock, processing plant, storage facility— anywhere you need to verify the safety and quality of your products and ingredients. Speed and Accuracy Measure water activity in 5 minutes or less (average read time: 2.5 minutes) with ±0.003 aw accuracy. AquaLab instruments are the fastest, most precise water activity meters available. Use (Almost) Anywhere Water activity is temperature dependent. Internal temperature control lets you set a measuring temperature between 15º- 50°C and use the instrument anywhere— even outside a climatecontrolled facility. How it Works Put a 7.5 ml product sample in a disposable cup, seal the sample chamber lid over the sample, and wait for vapor equilibrium. An infrared beam focused on a tiny mirror determines the precise dewpoint temperature of the sample. That dewpoint temperature is then translated into water activity. Easy to Clean The sample chamber lid flips up so contaminated sensors are quick to spot and easy to clean. Secure Data The 4TE stores time, date, and user information with every measurement and calibration, and can store up to 8,000 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. Easy to Use AquaLab Series 4TE makes water activity measurements quick, accurate, and simple. Using AquaLab, anyone, from a researcher in the lab to an operator at the line, can measure water activity in 5 minutes or less to 0.003 aw specifications. That means tighter control points, better quality, and a leaner operation.
