Description

IAQ(Indoor Air Quality) sensor, which has been designed to detect carbon dioxide gas in the air. This model has resolution by NDIR method, so it is an optimum device for ventilation of buildings, houses, etc. Also, the advantage of this model is compact size and easy installation. Description FEATURES High sensitivity and good resolution High technology adopted by NDIR method No calibration needed in installation No maintenance needed in normal applications Two type signal(DCV and DCA) output Easy installation Compact size (70㎜×122㎜×32㎜) Gas Detected : Carbon dioxide (CO2) Sensing Method : NDIR(Non-dispersive infrared) Detect Range : 0~2,000ppm Accuracy : ±30ppm ±5% of measured value Warm-up Time : Within 2 minutes Power Supply : 24Vac, 24Vdc±20%, 50/60Hz Output Signal : 0~10Vdc or 0~20mA Response Time : Within 150 sec (90%) Wiring : 4-wire Operating Temperature : 0 ~ 50℃ Operating Humidity : 0 ~ 95%RH (non condensing) Storage Temperature : -20 ~ 60℃ Storage Humidity : 0 ~ 95%RH (non condensing)
