Special Calibration Considerations: Hydrogen Chloride (PN° 823-0208-21)

Zeroing The Sensor:

There are no special zeroing considerations for this sensor. Complete zeroing instructions are provided in the SensAlert Plus User Manual.

Span Calibration:

It is recommended that this sensor be calibrated at the half-scale concentration of 5 ppm HCl. It is recommended that the sensor undergo a 3 to 5 minute pre-calibration exposure in order to season the calibration system. This pre-exposure ensures that the gas reaches the sensor at full concentration. The use of Teflon™ tubing is recommended with this gas to prevent gas absorption into the tubing walls. Complete span calibration instructions are provided in the SensAlert Plus User Manual.

Test-on-Demand Cell:

Test-On-Demand cell available for this sensor: PN° 821-0204-06 (Type S). It is recommended that the user set the cell intensity to 25% for new ToD Cells.
