Pro CO Analyzer with Low Pressure/High Temp Alarms & Flow Meter
This Pro CO Alarm analyzer combines carbon monoxide detection, a low-pressure alarm, an external high-temperature sensor, and a flow meter into a single unit. Optional regulator on input available. The included SPDT relay cable (10A @ 230VAC/30VDC ampacity) can connect to auxillary equipment to trigger external alarms, emergency backup systems, or compressor shutdown. Components are mounted in a water- and impact-resistant case with a clear cover that is compatible with outdoor and marine environments.
This version of the Pro CO Alarm analyzer detects:
(1) CO in air flow from an operating compressor in excess user-defined set points
(2) Compressor air outlet temperatures in excess of 350°F/177°C
(3) Low air supply pressure, factory set at 100 psi (7 bar)
Similar to SKU 9621, the 9621F Series is equipped with a flow meter. Choose from the standard model (SKU 9621F-LB) or add a low pressure/high pressure (LP>HP) regulator on input (9621F-HP-LB).
If the analyzer readings fall outside of alarm set points, a relay sounds a piezo alarm and illuminates one of three panel LEDs (one each for CO, temperature and pressure). This same relay (10A @ 230VAC/30VDC ampacity) can activate an external relay to automatically shut down compressors, sound an external alarm or activate emergency backup systems.
The system includes an external temperature sensor with 12-feet of cabling, an externally mounted calibration gas inlet and exhaust port.

WARNING: Never expose gas sensors to pressure or you may cause damage and/or false readings. Damaged sensors will not provide accurate gas analysis. Most gas analyzers can be used to analyze a regulated gas sample flow, the contents of a gas cylinder, or the flow from a regulator. The flow rate of gas must equal 1-5 L/min. To produce this flow, a Flow Restrictor and Regulator may be required. A faulty Flow Restrictor can lead to a false analyzer reading. Flow Restrictors should be regularly tested with a Flow Meter. Inaccurate gas analysis can lead to serious personal injury or death.
