3.2.1 Sensor Verification
The AquaLab Series 4 line of instruments contain a chilled mirror dewpoint sensor for
determining water activity. The 4TEV model contains both the chilled mirror sensor and a
capacitance relative humidity sensor. The performance of the sensors is verified by measuring
specially prepared calibration standards that have a specific molality and water activity.
Performance Verification Standards in four water activity levels are used for qualification:
0.250, 0.500, 0.760, 1.000 aw. The AquaLab dew point sensor will read each standard within
+/- 0.003 aw of the stated value. The capacitance (volatiles) sensor will read each standard
within +/- 0.015 aw of the stated value. To measure the water activity of the standards, follow
the instructions in the User's Manual for taking a reading.
