Pro CO Low Pressure / High Temp Analyzer

NU 9621

This Pro CO Alarm analyzer combines carbon monoxide detection, a low pressure alarm and an external high temperature sensor. Components are mounted in a water and impact-resistant case with a clear cover that is compatible with outdoor and marine environments. Available in two power options.

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)

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 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. Two power options available.

PLEASE NOTE: Never expose gas sensors to pressure or you may cause damage and/or false readings. Damaged sensors will not provide accurate gas analysis. Inaccurate gas analysis can lead to serious personal injury or death. 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.
