MODEL 2230R, Process Hydrogen Analyzer The safety of personnel is ultimately the responsibility of those who control process conditions. While this instrument may be able to provide early warning of imminent danger, it has no control over process conditions, and it can be misused. In particular, any alarm or control systems installed must be tested and understood, both as to how they operate and as to how they can be defeated. Any safeguards required such as locks, labels, or redundancy,

MODEL 2230R, Process Hydrogen Analyzer 1. DESCRIPTION The Model 2230R Process Hydrogen Analyzer is designed to detect and/or measure hydrogen as a component of a gas mixture. The hydrogen specific solid-state sensing element is designed for ease of use, interface flexibility and true process control. The electronics contains all the circuitry necessary to operate the sensor and present calibrated hydrogen readings to a voltage or current analog output and an RS232 or RS422 digital output

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 s
