CO2 Transmitter

Application CDW and CDD carbon dioxide transmitters are designed for monitoring and controlling environment of industry and commercial buildings. They can be used in working house, clean room, laboratory, machine room, office, airport, parking lot, station and museum, etc. where air quality control is necessary. CDW is for wall mount and CDD is for duct mount Features High performance NDIR digital sensor and circuit, ensure precise measurement and temperature compensation Stable and reliable 15 years sensor life and maintenance-free Fast response Light and state of art housing Optional output selection Specifications Sensor: NDIR Sensor, with ABC calibrate function and active gas diffusing Accuracy: See in models selection Response time: <10s (30cc/min, low flow gas) Drift: <±10ppm/year Range: 0 2000ppm or others Output: 4 20mA/0 10V or RS485 Relay output: SPDT relay, 1A/30VDC,0.5A/125VAC Power supply: 24VAC/DC±10% Load resistance: 500Ω (Current output) Display: LCD Display (optional) Display accuracy and resolution: 1ppm Working environment: 0 50°C,0-95%RH(Non-condensing) Storage temperature: -20 80°C Housing: ABS Protection: IP30 (CDW), IP65 (CDD) Optional LCD display: LCD display panel could be ordered and installed in field separately (CDW).
