Description
- Measuring principle: Electrochemical (EC)
- For toxic and combustible gases (CO, NO, NO2)
- Dual sensor (monitor 2 gases simultaneously)
- Expected sensor lifetime: > 3 years
- Signal transmission: RS-485
- Protection class: IP40
The EC22 DS uses two electrochemical (EC) sensors to detect the gases CO, NO and NO2. The different sensors measure the three gases in measuring ranges such as 0 to 10 ppm (NO, NO2) or 0 to 500 ppm (CO). Its automatic temperature compensation and the linearization of the measuring signals ensure high measuring accuracy.
The EC22 DS uses a digital RS-485 interface (Modbus protocol) to transmit signals. Test gases for function tests can be inserted using calibration adapters. The transmitter’s operating status is indicated by a status LED. Service and adjustments can be carried out on site using a smartphone app or magnetic pen (one-person adjustment).
