COMET T6445 | RS485 Temperature, Humidity & CO2 Transmitter — Duct Mount

Duct mount CO₂ concentration t-line WebSensor. Transmitter with built-in concentration CO₂, temperature, relative humidity sensor for duct mount. A multiple point CO₂ and temperature adjustment procedure leads to excellent CO₂ measurement accuracy over the entire temperature working range; this is a must for process control and outdoor applications. The dual wavelength NDIR CO₂ sensing procedure compensates automatically for ageing effects. The CO₂ module is highly resistant to pollution and offers maintenance free operation and outstanding long term stability. Green LED shines - CO₂ concentration 0 to 1000 ppm Yellow LED shines - CO₂ concentration 1001 to 1200 ppm Red LED shines - CO₂ concentration 1201 ppm and more INCLUDED IN DELIVERY:

• T6445
• Instruction Manual
• Traceable Calibration Certificate
• FREE software TSensor for Configuring of the Transmitter
