Lab-quality water activity measurements

21 February 2012

Labcell, UK distributor for Decagon Devices, has introduced the AquaLab Series 4TE water activity analyser, which is believed to be the fastest and most accurate instrument of its type

This easy-to-use, accurate and cost-effective instrument enables manufacturers in the food, pharmaceutical and cosmetic industries to take lab-quality measurements of water activity almost anywhere in the production environment, from goods inwards inspection through to storage facilities, line-side inspections and pre-shipping checks.

Of course, the instruments are also suitable for use in research and development departments when optimising the safety, quality and shelf life of new products.

The AquaLab is widely viewed as an industry-standard device for measuring water activity. Features introduced in the latest Series 4 TE model include a redesigned sensor block that simplifies cleaning, compliance with the requirements of the FDA's 21 CFR Part 11 rule regarding electronic records and signatures, and an improved user interface.

In addition, the Series 4TE benefits from temperature equilibration, with the configurable temperature range being 15 to 50 degrees C. Measurements are obtained in five minutes or less (the average read time is 2.5 minutes), and the instrument has a measurement range of 0.030 to 1.000 aw, an accuracy of +/-0.003 aw and a repeatability of +/-0.001 aw. For every measurement and calibration, the instrument logs the date, time and user. Up to 8,000 data points can be stored securely on the instrument.
