code: H7430
Humidity, temperature, atmospheric pressure transmitter with two relay outputs. Outdoor, indoor use.
Humidity, temperature, atmospheric pressure transmitter with two relay outputs. Outdoor, indoor use.
Built-in relative humidity, temperature, pressure sensors. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy. Three two-state inputs.
Included in delivery:
- H7430 sensor
- Traceable calibration certificate
- Quick start manual
- Technical support at discussion forum
