Product Details

The German MRU carbon dioxide detector M90 has low power consumption and dual band technology to ensure high accuracy and reliability of the instrument. The German MRU carbon dioxide detector M90 has a backlit display.

German MRU Carbon Dioxide Detector M90 Product Features:
The unique sturdy and simplified design of dual vent engineering; Dual band technology ensures high accuracy and reliability of the instrument.
The main applications of the German MRU carbon dioxide detector M90 are:
In the product quality and production process control of natural gas, it is usually necessary to detect the concentration of CO2, which ranges from 0-5% of the available gas to as high as 0-30% of the inlet CO2 concentration.
Some H2S removal chemical production processes can be fine tuned by increasing CO2 as much as possible, but cannot exceed the typical 2-4% pipeline standard limit. CO2 is a byproduct of combustion and also requires quantitative detection.
The main features of the German MRU carbon dioxide detector M90 are:

• True dual beam technology
• Long lasting reliability
• Low power consumption
• Alarm
Backlight 16 characters, 2-line display
4-20 mA output
Technical advantages of the German MRU carbon dioxide detector M90:

The M90 dual beam infrared CO2 detection system continuously measures and calibrates the short-term and long-term changes in measurement errors caused by head home generation and single beam CO2 sensors,
M90 is a composite CO2 sensor that uses less than 2 watts of power consumption
Provide linearized analog or digital measurement outputs. Optional items include adjustment kit point control relay. M90 is a defense system for Class 1, Division 1 Groups C&D within the industry
The most cost-effective product among explosive levels, with a standard measurement range of 0-20% CO2, and other measurement ranges can be set according to needs.
