Analog part

The BL798 is a rugged, accurate temperature and relative humidity probe. It measures relative humidity over the range of 0 to 100% RH and temperature over the range of -40°C to +160°C. Alternatively, the range can expanded from -40°C to +180°C.

FEATURES

RH accuracy up to 1.0%RH

Temperature accuracy up to 0.6℃

Temperature measuring range -40…+180℃

Full 0…100%RH measure, +80℃ measure

Modbus RTU over RS-485

Easy Installation and connection

Sensor purge improves long-term stability and chemicalresistance

APPLICATION

Industrial applications where periodic recalibration alone is not sufficient for maintaining the probe performance.

Industrial HVAC systems, cleanrooms, and environmental chambers.
