产品简介：
This uniquely rugged and simple design by Envent Engineering utilizes dual-beam technology for accuracy and stability.

应用：
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. Some H2S removal chemical processes can be fine-tuned by slip stream as much CO2 as possible to gain volume but not so much as to exceed pipeline tariff limits of typically 2–4%. CO2 is also a combustion byproduct and needs to be quantified.

产品特点：
True Dual-Beam Technology
Long-term stability
Low power consumption
Alarms
Backlit, 16-character, 2-line Display
4–20 mA output

Value
The M90 dual-beam IR CO2-detection system continuously measures and corrects for the short and long-term changes that caused measurement errors in first-generation, single-beam CO2 sensors. The M90 is a compact CO2 sensor which uses less than 2 watts of operating power, provides linearized analog or digital measurement outputs. Options include adjustable set point control relays.

The M90 offers industry-leading value in price for Class 1, Division 1 Groups C & D hazardous locations. Standard range is 0–20 % CO2 but other ranges available upon request.
