COMET T5341 – CO₂ Transmitter with External Probe, RS232

COMET T5341 CO₂ Transmitter External Probe RS232 

The COMET T5341 is a robust CO₂ concentration transmitter with a remote external probe, specially designed for demanding, aggressive, or hard-to-reach environments. The electronics remain protected while the probe is placed exactly where measurement is required: in humid rooms, dusty halls, corrosive areas, shafts, tanks, or production facilities.

With its extended measuring range up to 10,000 ppm, the T5341 is perfect for high CO₂ concentrations – e.g. in greenhouses, breweries, biogas plants, stables, or industrial processes. The 3-color LED indicator (Green/Yellow/Red) instantly displays air quality: Green ≤1000 ppm, Yellow 1001–1200 ppm, Red ≥1201 ppm.

The maintenance-free NDIR sensor with automatic calibration ensures years of precision. Via the RS232 interface with Modbus RTU protocol, the T5341 can be seamlessly integrated into any building automation, ventilation control, or SCADA system. The fully IP65-protected housing withstands even harsh conditions.

Whether for indoor air monitoring in challenging areas or process control with high CO₂ levels – the T5341 is the flexible and reliable solution.
