  • 產品說明
  • Optional features include a resistive temperature sensor output (with LCD display of temperature °C) a control relay with programmable setpoint, hysteresis and time delay.

  • ​LCD Display：
    Units: ppm (CO2), °C (optional temperature sensor).

  • A linear analog signal output of 4 to 20 mA, 0 to 5 Vdc or 0 to 10 Vdc is provided for connection to a building
    automation system.

  • The CO2 sensor incorporates a self-calibration feature to correct CO2 sensor drift.

  • This CO2 sensor is recommended for applications where the CO2 level will be close to normal (400 ppm) at least one hour per day. If the monitored space is occupied 24 hours or consistently maintains higher or lower levels of CO2, it is recommended that this feature be turned off, but yearly calibration will be required.
