HMP9 Compact Humidity and Temperature Probe

HMP9 is a general purpose Relative Humidity and Temperature probe, with 5 mm (0.2 in) diameter miniature probe head. Despite the small footprint, the probe head contains a HUMICAP® sensor that provides its industry standard humidity measurement performance. HMP9 has great stability, fast response time, and low hysteresis in a wide range of applications, where accuracy and fast stabilization of the measurement are important.

In environments with high concentrations of chemicals and cleaning agents, the chemical purge option helps to maintain measurement accuracy between calibration intervals. The chemical purge involves heating the sensor to remove harmful chemicals. The function can be initiated manually or programmed to occur at set intervals.

The probe is compatible with INDIGO range transmitters, or can be used as a stand-alone Modbus RTU transmitter.

The probe can be installed in ducts or channels. Installation accessories for installing the probe through 0.5 .. 2mm sheet metal, or in M10x1.5 tapped hole are included.

The probe is suitable for continuous temperatures in range of -40..+120 °C.

Process connection: M12/5 (MA) connector.
