  • Ideal for applications requiring low drift, versatility and reliability
  • Wide range 0-10%, high resolution 0.0001%
  • Dual wavelength infrared technology
  • Barometric pressure compensated
  • Not sensitive to flow rate changes


The MA-10 Methane Analyzer is a fast-responding CH4 analyzer with a wide measurement range (0-10%) combined with high resolution. It’s ideal for constant volume/stop-flow and flow-through respirometry of methane-producing organisms.

Barometric pressure compensation is standard. Direct modulation of the infrared source translates to greater ruggedness and reliability. The optical bench is differential (dual-wavelength), reducing drift and practically eliminating sensitivity to water vapor. Our proprietary optical bench uses a low volume, gold over nickel plated optical path and the highest quality machining, with premium emitter, differential detector and optical filtration components.

The MA-10 methane analyzer is easily interfaced to any data acquisition system or data-logger. Eleven ranges of voltage proportional to carbon dioxide concentration or partial pressure, plus multi-range outputs proportional to barometric pressure and optical path temperature, are available at the rear panel from high-quality BNC connectors.  A serial output is standard.

Operation is intuitive and flexible, with all functions accessible via high quality rotary encoders. Adjustments and settings are permanently retained in the absence of power.
