Dual-Gas Methane/Carbon Dioxide Infrared sensors

Our Dual-Gas Methane (CH₄) / Carbon Dioxide (CO₂) sensors are revolutionary devices for the simultaneous measurement of Methane and Carbon Dioxide in a single sensor package. They acheive this whilst only consuming the power of a single infrared sensor. The sensors also have the additional benefit of a pre-characterised 0-2% Propane measurement range included as standard.

The sensors provide accurate measurement of gas levels using infrared gas sensing techniques. Various versions are available with combinations of ranges up to 100% volume Methane and 5% volume Carbon Dioxide. They consume the power of a single infrared sensor and therefore provide prolonged battery life when used within portable gas detectors.

The Hydrocarbon channel provides simultaneous readings for both High Resolution Methane and Propane.

• Hydrocarbon Channel Resolution – 0.01% for range 0 to 10% Vol. and 0.1% for range 10% to 100% Vol. (CH4)
• Carbon Dioxide Channel Resolution – 0.01% Vol. (CO2)

The sensors are part of the ‘Platinum’ Series and are available in Industrial Ex d IIC Certified, Mining M1 Certified and Non-Certified versions. They are also UL approved. Low power and EN50271 / SIL1 certified software versions are also available in all combinations.
