Multitec 540 - Biogas / Sewage plant / Landfill Gas measuring

With infrared Methane and Carbon Dioxide sensors.

Measures up to 5 gases simultanously including Oxygen, Hydrogen Sulphide and Carbon Monoxide

sensor in use

Producing Biogas in anaerobic digesters makes harsh demands on equipment used to measure the gas composition. The robust Multitec® 540 is designed to work in this harsh environment. The MT540 Biogas monitor can measure up to five gases simultaneously.

The MultiTec 540 Biogas analyser uses longlife gas specific infrared sensors to measure both methane and carbon dioxide. Optional oxygen, hydrogen sulphide and carbon monoxide sensors may be added. This makes the MT540 Biogas analyser ideal for use in Biogas producing waste disposal sites, sewage plants and biogas plants.

The measured gas results are displayed all at once on the large LCD screen.

Measured biogas values may be stored in the onboard memory and can be uploaded to difficulty to a PC via the USB link.
