Pro H2O Alarm Analyzer Panel Mount


The Pro H2O Analyzer measures moisture (H2O) levels in gases in the range of 0 to 500 parts per million (ppm). The analyzer is designed to either verify H2O concentration in stored gas cylinders or monitor continuous compressor gas flow. Extend the service life of air filtration systems by monitoring excessive moisture levels. Sample manifold sold separately. Choose from two power and two module options.


Designed for installation on a compressor control panel or other flat surface, the Nuvair Pro H2O Alarm panel mount analyzer measures moisture levels in breathing gas mixtures or air. Audible and visual alarms for low and high moisture content can be set by the user. If the alarm sounds, the analog output can activate an optional relay that shuts down compressors automatically, sounds a remote alarm, or activates an emergency backup system. Sample manifold sold separately.


  • Audible and visual alarms for high moisture content
  • Universal power options
  • Working pressures of 100–6000 psi
  • No limit on flow rates
  • Programmable alarm thresholds
  • Fast response
  • Easy to operate, reliable and accurate
  • Made to be installed in multiple systems

Available Options

  • Three available external sample manifold types
  • Optional relays for external alarm or compressor shutdown before filter elements saturate
  • Choose from 110/220V wall plug-in [international] power or DIN rail power
  • Choose from two available modules: FAILSAFE or SMART START

Adding the FAILSAFE Module to your Nuvair Pro Alarm analyzer will automatically disable integrated power equipment if: (a) Analyzer power is interrupted, or (b) Analyzer goes into alarm. Adding a SMART START Module to your Nuvair Pro Alarm Analyzer will automatically power-up the analyzer in tandem with integrated power equipment, like a compressor.

Choose one of two available power options and two available module upgrades by using the Power & Module Options dropdown menu (above).
