Rapidox 1100 Methane Gas Analyzer

The Rapidox 1100-M methane (CH4) gas analyser is the company’s most cost-effective and versatile range of CH4 gas analysers fitted with an infra-red gas sensor or a tuneable laser diode sensor depending on the application.

The infra-red (IR) sensor is the most common and preferred solution for methane (natural gas) measurement providing fast and accurate gas analysis over the range 0-1% to 0-100% CH4 and is particularly suitable for aggressive industrial applications as the sample gas is filtered for dust and particles and is non-condensing. IR sensors are highly suitable for measuring gases that absorb infra-red light such as CO2, CO & CH4 particularly in percent levels of concentration. Different sensor lengths are available to allow different ranges of the gas to be detected hence the importance of selecting the correct range for your application.
