COMET T3411 | RS485 Temperature & Humidity Transmitter (Built-in Sensor)

With an RS485 digital serial output for Modbus-compatible systems, the COMET T3411 measures temperature, relative humidity, and dew point for HVAC monitoring, building automation, cleanrooms, and industrial environments. Multi-drop wiring capability allows several units to share a single bus, simplifying installation where digital communication to PLCs or data loggers is preferred.
