COMET T3319 – Temperature and Humidity Transmitter, Cable Probe, RS232

COMET T3319 Temperature and Humidity Transmitter RS232 

The COMET T3319 is a robust industrial transmitter for temperature and relative humidity, equipped with a remote probe on a 1-meter cable. It is ideal for use in demanding or aggressive environments. The electronics remain protected while the probe can be flexibly positioned in hot, humid, or hard-to-reach areas such as drying chambers, climate cabinets, production halls, greenhouses, or process plants.

With its wide probe temperature range up to +105 °C and 0–100 %RH, the T3319 is perfectly suited for high-temperature humidity measurement. It automatically calculates dew point, absolute humidity, specific humidity, mixing ratio, and specific enthalpy — all directly available via the RS232 interface with Modbus RTU protocol (and compatible with Advantech ADAM).

The fully IP65-protected housing withstands harsh conditions, while the probe is IP40-rated. The large dual-line LCD displays temperature, humidity, or dew point and can be switched off for continuous operation.

The T3319 is a proven solution for precise climate monitoring in industrial settings — maintenance-free, long-term stable, and backed by a 3-year warranty.
