Comet T5240 – CO2 transmitter with 0–10 V output

The Comet T5240 is the CO₂ concentration transmitter with a 0-10V output, a large LCD display, and an LED traffic light function. For precise indoor air monitoring in offices, schools, and industry – adjustable measuring range.

The Comet T5240 is a reliable CO₂ concentration transmitter with a 0-10V output and an integrated sensor. The device was developed for the precise monitoring of indoor air quality and clearly indicates the CO₂ level 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.
