Comet T5141 – CO2 Transmitter (4-20 mA, external probe)

The Comet T5141 is the CO₂ transmitter with a 4-20mA output and an external probe (1m cable). Featuring an LED traffic light, a large LCD display, and an adjustable measuring range – ideal for precise indoor air monitoring.

The Comet T5141 is a robust CO₂ concentration transmitter with a 4-20mA output and an external probe. The device is housed in a durable, waterproof enclosure (IP65) and is excellently suited for precise monitoring of indoor air quality in industry, offices, schools, and technical facilities.

The external CO₂ probe with a 1-meter cable allows for flexible measurements. The large, two-line LCD display can be switched off if required. The clear LED traffic light function immediately shows the current CO₂ level: Green (0–1000 ppm), Yellow (1001–1200 ppm), and Red (from 1201 ppm).

The measuring range is possible up to 10,000 ppm. The output is freely adjustable by the user – a practical and accurate solution for air quality monitoring.
