3.5.3 Calibration of a Toxic Gas Channel

Equipment Required

 The calibration cover

 A calibration adapter for the type of gas to be calibrated:

 For reactive gases, 8” Teflon lined tubing, cylinder regulator and reactive gases (ex. H2S, NH3, SO2, HC1 etc…)

 For non-reactive gases, Tubing and cylinder regulator

 A cylinder of calibration gas with a known content and corresponding to the type of sensor to be calibrated

Preparing the OMNI-4000

• Attach the OMNI-4000 calibration cover. See Figure 3-8

• Connect the calibration gas cylinder to the calibration cover with a vinyl hose

• If the channel has not been selected refer to the "Selecting the Channel for Calibration" paragraph

Use:

Cylinder Regulator 02506-004 with 17 liter cylinder

Cylinder Regulator 02506-002 with 34 liter cylinder

(ex. H2S, NH3, HCL etc.)

Cylinder Regulator 02506-005 with 103 liter cylinder

(ex. CO2 )

Calibration Arrangement for the Majority of Gasses

Humidifier
