The Model M90 is designed to monitor percent level CO2 concentrations in natural gas applications. An infrared, dual-beam technology is incorporated into the design of the instrument. The
M90 can be included as an additional measurement with other
Envent analyzers, or can be offered as a stand-alone analyzer with
an integrated sample conditioning system.
Dual-Beam NDIR Technology.
Low power consumption (2 watts).
Dual alarm outputs.
4-20 mA output.
RS-232 and RS-485 Modbus communications.
Two Adjustable set point control relays.
Full service & training.
Available with differing sample systems and accessories as required in various applications.
The M90 dual-beam infra-red carbon dioxide detection systemcontinuously measures and corrects for the short and long-termconcentration changes that caused measurement errors in first
generation (single beam) carbon dioxide sensors.
CO2 is measured routinely in natural gas for product quality and process control purposes. Common ranges are from 0-5% for sales gas and up to 0-30% for inlet CO2 concentration.

Certain H2S-removal chemical processes can be fine-tuned by CO2 slipstreaming.
