AquaLab is the fastest and most accurate instrument for measuring
water activity, giving readings in fi ve minutes or less. Its readings
are reliable, providing ±0.003 a
to clean and checking calibration is simple.

AquaLab Model and Options

Series 4: Uses chilled-mirror dewpoint sensor, but lacks tempera-
ture control features of premium models.
Series 4TE: User-selectable internal temperature control model,
uses thermoelectric (Peltier) components to maintain internal tem-
perature.
Series 4TEV: Uses both a chilled-mirror dewpoint sensor and a ca-
pacitance sensor for measuring non-volatile and volatile substances,
respectively. Either sensor is easily selected using the instrument's
menu system.
Series 4TE DUO: Uses chilled-mirror dewpoint and programmed
models obtained from isotherm data to give the user both water ac-
tivity and moisture content simultaneously in fi ve minutes or less.
