Description
Carbon dioxide transmitter CO₂ ։ Evicon – E2618-CO2
- Stable long-life photoacoustic or optical NDIR sensor
- Measurement ranges: 0…10,000 ppm / 0…40,000 ppm / 0…5 %vol CO₂
- Resolution: 1 ppm / 10 ppm / 0.01 %vol CO₂
- 2 × 4–20 mA or 0–10 V analog outputs and RS485 interface
The E2618-CO₂ carbon dioxide transmitter is a member of the PluraSens® family of multifunctional measurement instruments.
Typical applications include HVAC and indoor air quality control in public, office, and industrial buildings, greenhouses, underground parking facilities, boiler rooms, and other enclosed spaces where elevated concentrations of carbon dioxide may accumulate.
The instrument uses a fully calibrated and temperature-compensated photoacoustic or optical NDIR gas sensor, providing excellent repeatability, stability, and long service life. Optional ambient pressure compensation is available for absolute pressures ranging from 0.5 to 2 bar.
Two analog outputs and an RS485 digital interface supporting the industry-standard Modbus RTU protocol enable seamless integration with safety systems and building automation systems.
