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.
