CO2 Sensor MA Series (Carbon Dioxide Concentration Meter)

Domestic products
The MA series CO2 monitors are wall-mounted CO2 (carbon dioxide) concentration meters that use a solid electrolyte or infrared absorption sensor detection method and are equipped with functions such as a digital display of measured values and an analog output signal. They are available with an alarm specifications that outputs a warning value mechanical relay output or sounds a buzzer, and with a control function that is equipped with a relay output for adjusting the CO2 concentration. There is also an aspirating type that can measure the CO2 concentration by aspirating gas from places where a CO2 monitor cannot be directly installed.

  • Solid electrolyte method: Less susceptible to the effects of high humidity and atmospheric pollution, making it excellent for measurements in semi-open spaces with ventilation.
  • Infrared absorption method: Less susceptible to the effects of coexisting gases that can cause measurement errors, making it excellent for measurements in closed spaces where gases are less likely to diffuse. The sensor module can be replaced on-site.

Continuous monitoring of CO2 concentration for environmental management

  • Equipped with a red LED digital display that makes the measurement values easy to read.
  • Two types are available: with alarm function and with control function.
  • There are two types of transmission signal output: 4 to 20mADC and 1 to 5VDC.
  • Small, lightweight, and simple wall-mounted design.
