Pro Duo Multigas Alarm Analyzer Series
The Nuvair PRO DUO series of gas analyzers come in different pairings to match your multigas analyzing requirements. Mounted in a rugged, water-resistant carrying case, the PRO DUO has two user-programmable audible and visual alarms for each gas sensor. Powered by a rechargeable lithium-ion battery (or 24V external DIN power for 9599-DP and 9599F-DP), the PRO DUO comes in the following configurations: Carbon Monoxide/Carbon Dioxide [CO/CO₂: SKU 9598-LB], Oxygen/Carbon Dioxide [O₂/CO₂: SKU 9618-LB], Oxygen/Carbon Monoxide [O₂/CO: SKU 9623-LB], or Carbon Monoxide/Moisture [CO/H₂O: SKU 9599-DP]. Each PRO DUO is available with an optional flow meter [SKU 9618F-LB, 9598F-LB, 9599F-DP, 9623F-LB] and is mounted in a rugged, water resistant mounting case with clear lid.
The Nuvair Pro Duo series of multigas alarm analyzers are mounted in rugged, water-resistant cases. 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. All -LB models come equipped with a rechargeable lithium-ion battery and include a universal 110/230-volt charger. The -DP models are DIN powered.

Replacement Sensors
All Nuvair Pro Duo analyzers are custom-made at the time your order is placed. If a rush order is required, please contact the sales team for estimated lead times.
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.
