Comet T5140 – CO2 Transmitter (4-20 mA)

The Comet T5140 is the CO₂ concentration transmitter with a 4-20mA output, large LCD display, and LED traffic light function. For precise indoor air monitoring in offices, schools, and industry – adjustable measuring range.

The Comet T5140 is a reliable CO₂ concentration transmitter with a 4-20mA output and an integrated sensor. The device was developed for precise monitoring of indoor air quality and clearly indicates the CO₂ content via a three-color LED traffic light.

The green LED lights up at 0–1000 ppm, the yellow LED at 1001–1200 ppm, and the red LED from 1201 ppm. The large, two-line LCD display can be switched off if required. The output range is freely adjustable by the user.

The compact and robust housing (IP30) is excellently suited for use in offices, classrooms, conference rooms, and industrial environments.
