Abstract
A method and means is disclosed for carrying out the calibration of a gas monitor. The calibration is effected by providing a calibration gas containing a precise amount of the constituent that is measured by the gas monitor. That calibration gas is introduced into the gas monitor and passes therethrough in a closed system such that leakage of calibration gas to the surrounding environment at the inlet to the gas monitor and from the outlet of the monitor is prevented. The calibration gas is further stalled in the gas sensor chamber of the gas monitor for the operator to make necessary adjustments to the gas monitor at no flow conditions of the calibration gas.
