Fast Shipping Dwyer CDTR-2D4F4 Carbon Dioxide/Rh/Temperature Transmitter

Dwyer CDTR-2D4F4 is a Carbon Dioxide/Rh/Temperature Transmitter with a range of 0 to 2000 or 0 to 5000 PPM for CO2. It has an accuracy of ±40 PPM + 3% of reading for CO2 and ±2% for RH. The transmitter operates with a power requirement of 16 to 35 VDC / 19 to 28 VAC and has a response time of 2 minutes for a 99% step change. The device features a single-beam, dual-wavelength NDIR sensor and can measure humidity from 10 to 95% RH (non-condensing). Output options include current, voltage, relay, or RTD/thermistor. The CDTR-2D4F4 has an enclosure rating of NEMA 4X (IP66) for duct mount and IP20 for wall mount. It consumes an average of 2 watts of power and has a non-linearity of 16 PPM. The temperature dependence is ±8 ppm/°C at 1100 PPM, and the pressure dependence is 0.13% of reading per mm of Hg. The device has a velocity range of 0-4000 FPM (20.32 m/s).
