AWQ-Temp AwQuick The HP23 considers temperature to be stable when the rate of change of the
temperature signal is less than the specified value.

测量选项
The HP23 uses an algorithm to project the full equilibrium value (water activity) of the product sample:
1) The value of the humidity signal is constantly monitored
2) The stability of the temperature signal is constantly monitored
3) After an initial period of time (dwell time), the humidity data is used to project the end value of the
equilibration process (water activity). The measurement ends automatically as soon as the projected Aw
value is stable. At that time, the HP23 freezes the display.

The measurement is automatically ended and typically requires about 5 to 6 minutes.
With the default dwell time of 4 minutes, the difference between the AwQuick mode and full product
equilibrium is typically 0.005 aw or less. The value of the dwell time can be set by the user (see
SETTINGS). This value represents a tradeoff between speed of measurement and accuracy. Generally,
