Honeywell HSCD series carbon dioxide (CO2)sensors include two types: indoor installation and duct installation. They are mainly used for detecting carbon dioxide concentration in air of indoor and duct.
Features ➢ Use high-precision single/dual-wavelength NDIR sensors.➢ Optional display function, LCD digital display shows clearly.➢ CO2 sensing component module can be replaced on site.➢ Multiple software and hardware protection design ensures high stability.➢ CO2 sensors can be manually calibrated on site.➢ The air duct type adopts a screw-free clamshell snap-on design, making wiring and commissioning easy.➢ Integrated RS485 matching resistor to facilitate on-site commissioning(Modbus models only).➢ RS485 isolation design can isolate high voltage and enhance immunity to ground loops and common-mode signal interference (Modbus models only).
Specification:
Humidity Range: Typically 0% to 100% RH
Accuracy: ±2% to ±5% RH
Resolution: 0.1% RH (varies by model)
Response Time: ~5 to 15 seconds
Operating Temperature: −40°C to 80°C (depends on type)
Output Type: Analog (0–1V, 4–20 mA) or Digital (I2C, SPI)
