SUB Multigas Colour (CO, CO2, O2, Moisture, Gas Temp)


Fully featured Multigas analyser fitted with CO, CO2, O2, Moisture and Gas Temp sensors


DE-OX® SUB is a general purpose measurement instrument able to be connected to a large number of sensors in any combination of them. Its application includes continuous ambient gas monitoring, hyperbaric chambers, safety, medical, air quality etc.

Standard available configurations include:

  • Oxygen
  • Helium
  • Carbon Dioxide
  • Carbon Monoxide
  • Humidity
  • Gas temperature
  • Pressure

It is possible to connect the instrument to many other sensors and to change the sensors and instrument configuration.

The instrument is installed into an extra heavy duty water proof Explorer case on an aluminum oven painted panel. It is easily possible to install the main instrument and the sensors in external panel.

Optional external Dew Point sensor. If an extra accuracy is required, it is dscn4554possible to connect an external thin-film aluminum oxide moisture sensor for detection of humidity up to -110°C dew point (0.001 mg/m3 or 0.001 ppmV). In this configuration the instrument gives also absolute humidity and PPMV at 21.1°C (70°F) and 1 atm.
