HMP7 Humidity and Temperature Probe for High Humidity, Modbus, 0.8%RH accuracy

HMP7 Humidity and Temperature probe is designed for applications that involve constant high humidity or rapid changes in humidity and temperature in such as drying and test chambers, combustion air and other humidifiers and meteorological measurements where measurement performance and chemical tolterance are essential. The design of the probe head is pressure and vapor proof and suitable for continuous temperatures in -40..+180 °C (-40..+356 °F)

The HMP7 can be used as stand-alone Modbus RTU digital transmitter, or used together with INDIGO200 series of transmitters. The high-temperature tolerant cable in the probe is 2 meters. The probe can be connected directly to the Indigo201 or with M12/5M extension cables up to 30 m

The probe is equipped with HUMICAPR2 composite sensor. Sensor purge functionality improves measurement performance under applications where the probe is exposed to high chemical concentrations

Probe warming function helps avoiding condensation under high humidity by heating the probe and sensor element above the dew point temperature. When probe warming is enabled, the device outputs dew point temperature and other humidity parameters which are not temperature dependant. If true ambient temperature is measured with e.g. TMP1 temperature probe, the compensation value can be written to the HMP7 over the Modbus and true relative humidity in the ambient temperature can be obtained.
