BIOGAS 5000 Gas Analyzer
The results of the calibrations will need to be recorded to monitor over time whether the
frequency of calibration needs to be increased or decreased relative to the confidence
required.
The confidence required will be driven by the site specific / user requirements.
When undertaking the monitoring with an understanding of the history of the gas levels of that
site, a calibration check could be triggered if the readings measured are different to what is
expected.

Calibration gases
User calibration of a gas analyzer will greatly improve the data accuracy in the range of the
calibration gases used. This may cause less accurate readings of concentrations outside this
calibrated range. Users should select the correct calibration gas for the expected gas levels
on their particular application.
To improve calibration at lower levels requires the use of gas mixtures 1 and 2.
To improve higher levels use gas mixture 3.
For standard CO only 100ppm CO gas is needed.
For CO (H
compensated) both CO 100ppm and H

The following table indicates the different gas mixture canisters used for calibration:
Calibration gas
Mixture 1
Mixture 2
Mixture 3
These are for general use but other gas concentrations can be used.

Note
Other gases could cause cross-gas effects. If you suspect a cross sensitivity
problem please contact the Technical Support Team at QED at

The above gases and most other gas concentrations can be supplied by QED.
