Temp Eq:
Th e Temperature Equilibration option allows you to set the level of
temperature equilibration desired before the water activity measure-
ment begins. Th e range is 0.5 to 4.0°C. A setting of 4.0°C begins
the measurement immediately (assuming the sample is not >4.0°C
above or below the block temperature). A setting of 0.5 °C will
cause the instrument to wait until the sample temperature is within
<0.5°C of the block temperature before starting the water activity
measurement.
Sensor:
In the AquaLab Series 4TEV model only, this option indicates the
selected sensor type, either dewpoint or capacitance (Th e Series 4
and 4TE models will always be Dewpoint). Pressing Enter when the
Sensor option is highlighted allows you to change between a capaci-
tance sensor or chilled mirror dewpoint sensor for sampling with or
without volatiles, respectively.
