Subject: Sensor Calibration Temperature
Product: SEC Signature DIR EtO/H2O Gas Analyzer
Sensor Electronics recommended the following calibration procedures to be used by customers to calibrate the SEC Signature DIR in the field:
Procedure Calibration SEC Signature DIR ETO 7204 Procedure Calibration SEC Signature DIR H2O 7204 H2O
Both of these calibration procedures include a step to heat the sensor to 42 degree C (+/- 4 degree C) prior to applying any calibration gas. This temperature is recommended for the normal operating temperature to be ambient.
Sensor Electronics recommended to calibrate the sensor about 10 degree C (+/- 5 degree C) higher than the normal operating temperature, to ensure that there is no moisture build up on the sensor.
For a normal operating temperature of 54 degree C, the calibration temperature would be about 60 to 70 degree C.
For both calibration procedures, Sensor Electronics recommended to apply 99.9 % Nitrogen gas prior to initiating zero operation.
