Vaisala HUMICAPâ Humidity and Temperature Probe HMP7 is designed for applications that involve constant high humidity or rapid changes in humidity such as drying and test chambers, combustion air and other humidifiers and meteorological measurements where measurement performance and chemical tolerance are essential. 

Vaisala is the original innovator of the thin-film capacitive humidity measurement technology, which has now become the industry standard in humidity measurement. HUMICAPâ technology results from Vaisala's 40-year experience in industrial humidity measurement, providing the best stability, fast response time, and low hysteresis in a wide range of applications.

Probe heating functionality heats up not only the sensor, but the whole probe head. When probe temperature is heated above dew point temperature, condensation on the probe can be avoided while measuring the dew point temperature of the process. By setting the temperature compensation value obtained, for example, with the TMP1 temperature probe, true relative humidity at process temperature can be measured while avoiding condensation by elevated probe temperature.

Indigo transmitters o„er a variety of connectivity options through analog signals or digital outputs, configurable relays, and wireless (WLAN) configuration interface, providing a suitable solution for all industrial humidity measurements. The cable length between the probe and transmitter can be extended to up to 30 meters.

The probe is plug and play compatible with Vaisala Indigo™ series of transmitters, or it can be used as a standalone digital Modbus RTU transmitter over RS-485 serial bus. For easy-to-use access to field calibration, device analytics, and configuration functionality, the probe can be connected to Vaisala Insight™ Software.

Each probe is manufactured and individually calibrated in Vaisala's worldclass facility in Finland. The traceable factory calibration certificate is included also in electronic format in the probe. Validate and maintain the accuracy by calibrating the instrument on the field, or use Vaisala's easy and thorough calibration services.
