Equipment
To calibrate the WatchGas QGM the follow equipment is needed:
•
WatchGas QGM
•
WatchGas QGM Calibration adapter
•
0.5 L/min regulator
•
Last-O-More hose
•
WatchGas IR link (optional)
•
Calibration gas
The use of the WatchGas IR link and IR link software is not required, but it's certainly recommended. Span
values can only be changed using the IR link software.
The WatchGas QGM can only measure O
gases. Note that these gases are available in a multi-gas mixture. Calibrating using a multi-gas mixture is
most cost and time efficient.
Adequate safety measures should be taken when working with these type of gases. Avoid personal
exposure at all times by working under a fume hood and/or wearing personal protective equipment.
