CALIBRATION PROCEDURE
Before beginning calibration, make sure you have the following items: A cylinder of calibration gas, fixed
flow regulator and an appropriate calibration cup connected to the regulator via a length of flexible
tubing. If necessary, a cylinder of ‘zero air’ may be necessary if the absence of target gas cannot be
confirmed. GDS Corp recommends a flow rate of 0.5 liters / minute for standard gases and a flow rate of
1.0 liters / minute for highly reactive gases such as chlorine or chlorine dioxide.
