Powerful Water Activity Meter

September 30, 2014

The new AquaLab TDL water activity meter looks like an AquaLab 4TE, but it has powerful new technology under its hood. The chilled mirror sensor has been replaced by a tunable diode laser, focused on the precise wavelength of water vapor. Unlike chilled mirror and capacitance sensors, the laser is not affected by volatiles. It is also a more accurate, faster, and more reliable water activity sensor, with a fully sealed chamber and no moving parts.
