HW group: HTemp CO2 485-RTU T6440

CO₂, temperature and humidity transmitter with RS485 and LCD

The HTemp CO2 485-RTU T6440 is the combined T6440 transmitter from COMET SYSTEM. Its standard ranges are 0–5000 ppm CO₂, −10 to +50 °C temperature and 5–95% RH. The LCD displays readings, while three LEDs indicate the CO₂ concentration.

RS485 with Modbus RTU connects it to a supervisory monitoring system. The supply voltage is 9–30 V DC. The electronics are rated IP30 and the sensors IP40. The T6440 does not measure barometric pressure. An extended CO₂ range is a separate manufacturer option and is not part of the standard version described here.
