MODEL 2230R, Process Hydrogen Analyzer

∙If the unit gets exposed to extended periods of no H₂ (or some Oxygen), condition the sensor as described in the Start-up section and follow-up with a Field Verification (and Field Calibration, if needed).

∙Effect of pressure: The Model 2230R Analyzer is hydrogen specific and sensitive to only the hydrogen partial pressure in the gas stream. Since changes in total gas pressure will affect the hydrogen partial pressure, they will also affect the sensor readings. For instance, at one atmosphere pressure, a 50% H₂/N₂ mixture will be reported as 50% from the unit. At 1.1 atm, the reading will increase to 55% and two atms will result in a reading of 100%. In fact, the Model 2230R Analyzer are capable of measuring multiple atmospheres of hydrogen and readings above 100% H₂ are interpreted as hydrogen pressures above one atmosphere. So, for example, a reading of 150% H₂ means 1.5 times the hydrogen pressure of a 100% H₂ concentration at one atmosphere. At the factory, the units are calibrated at one atmosphere pressure. Performing the Field Calibration at the operating pressure will display the pressure corrected reading. For example, if the local atmospheric pressure is 0.97 atm, doing a Field Calibration will correct for this.

∙Verification/Calibration gas bottle accuracy: The inaccuracy of the gas bottle concentration will directly affect the measured accuracy by the units. During factory calibration, the units are calibrated with high accuracy gases (as high as ± 0.02% accurate). It is strongly recommended that the user perform calibration with similar high accuracy gases to maintain the accuracy specified in the manual.
