Nuvair Pro O2/CO2 Alarm Analyzer in Watertight Box
The Nuvair Pro O2 / CO2 multigas alarm analyzer detects levels of oxygen (O2, in percentage) and carbon dioxide (CO2, in parts per million) in ambient air and compressed (stored) or continuous flow (compressor output) gases. Independent LCD gas readouts. User-definable alarms for each gas. Mounted in a waterproof hard case.
The Nuvair Pro O2 / CO2 multigas alarm analyzer is mounted in a rugged, water-resistant case. Each sensor has two user-programmable audible and visual alarms. The internal sensors are plumbed together to monitor a single input. The analyzer has visual and optional audible alarms for each gas.
An audible alarm sounds if any alarm set point is reached. When in alarm, the analyzer's analog output can activate an optional relay that shuts down compressors automatically, sounds a remote alarm, or activates emergency backup systems. Comes equipped with a rechargeable lithium-ion battery and universal 110/230-volt charger.
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.
- Monitors oxygen and carbon dioxide levels to ensure compliance with breathing air standards for CGA, NFPA, OSHA, CSA, EN norms, and others.
- Oxygen reading in any mix in the range 0.0–100.0% of volume
- Carbon dioxide reading in parts per million (ppm)
- Two (2) custom audible and visual alarms for each gas
- Oxygen sensor life up to 36 months
- User-replaceable oxygen sensor
- Carbon dioxide sensor life up to 10 years
- Robust waterproof hard case
- Automatic calibration of O2 and CO2 sensors
