Calibration
Analyzer calibration must be verified on a daily basis. Improper calibration may result in an
incorrect reading, delivering inaccurate levels of gas being monitored.
Nuvair offers two gas testing kits for the Analyzer Trio. A Helium free gas is
recommended. See addendum for more information.
Analyzer calibration must be verified on a daily basis. Improper calibration may result in
an incorrect reading, delivering inaccurate levels of gases or moisture being monitored.
This Analyzer must always be checked with a calibration gas and used with gases
regulated and supplied at atmospheric pressure (0 psi). Use of gases at higher
pressures may result in incorrect readings and may damage the Analyzer. Inaccurate gas
analysis can lead to serious personal injury or death.
Checking Calibration or use of the Analyzer with a low battery may result in inaccurate
readings. Inaccurate gas analysis can lead to serious personal injury or death.
If the Analyzer has been subjected to a recent change in ambient temperature, allow it to
stabilize for one hour before checking calibration.
Verify calibration on a daily basis. Breathing gas applications require the use of a certified
calibration gas with no moisture concentration and flow rate of 1.0-5.0 L/min. The equipment to
produce this flow is available from Nuvair. See Spares and Accessories section.
To assure the greatest accuracy for other applications, use the calibration gas concentration
closest to the expected concentration in the gas being measured.
