Pro CO Analyser with Low Pressure and High Temp Alarms

The Pro COTM Carbon Monoxide Analyser with low pressure and high temperature alarms measures carbon monoxide (CO) levels in gases in the range of 0 to 100 parts per million (ppm). It can be used to measure the CO content in gas mixes that may be contaminated due to the introduction of CO from internal combustion engines or other devices where CO is a byproduct. This unit is designed to verify CO concentration in continuous air flow from an operating compressor. In Addition, the unit includes a High Temperature Alarm that will activate if the compressor’s air outlet reaches 177°C, and a Low Pressure alarm that will activate if the air pressure supplied to the unit drops below a set value (factory set at 0.07 bar). The Analyzer is battery powered and includes an LCD display, red alarm light, Piezzo alarm and hinged clear water-resistant case. The Analyser uses a Flow Meter/Regulator to deliver sample gas to the Sensor.

This analyser comes with two options:

  • Rechargeable Lithium Battery (Part# 9621-LB)
  • Wall Plug-in (International) (Part# 9621-E)

We have combined our Pro CO analyzer with a compressor low pressure and high temperature sensor that provides audible and visual alarms for all. This combo meets OSHA requirements for offshore commercial breathing air compressors and the Army Corp of Engineers spec. Audible alarm at 10 ppm CO, accuracy of +-0.1%, self powered by batteries, easy to operate, reliable and accurate Carbon Monoxide gas analysis.
