GEM5000 Gas Analyzer
Page 59 of 102
As the regulator’s flow is factory set, it only requires a few turns to open, no adjustment is
necessary.
Exhaust port
When the gas analyzer is being calibrated, there are two
possible exits for the gas, via the usual manner out of the
exhaust (yellow) port of the analyzer or in cases of over-
pressurisation the 1/16
”
port on the red pressure relief valve
located on the regulator.
It is recommended that both ports have exhaust tubing
attached.
The exhaust tubing must emerge in a well-ventilated area.
Ensure there are no leaks in the tubing and connections.
The calibration of the gas analyzer should be carried out in a
safe area with all necessary precautions taken when using
potentially dangerous, explosive or toxic gases.
Note: There is also potential for gas to expel from the internal flow (blue) port of the
gas analyzer (applies to the GA5000 only).
9.5 Calibration equipment
The diagram below displays the regulator and tubing equipment for user calibration:
Certified calibration gas, available in either 29 liter, 34 liter or 58 liter gas canisters
are supplied with the Landtec calibration kit. Please refer to the Landtec website
www.landtecna.com for further information.
The regulator supplied with the calibration kit is pre-set for flow and pressure rates
that are factory set.
If you are using a non Landtec supplied regulator, please ensure that it does not
supply any greater than 200 mbar pressure.
