Relative Humidity and Temperature Probe HMP7
Relative Humidity and Temperature Probe HMP7
Vaisala HUMICAP® Humidity and Temperature Probe HMP7 is designed for applications which 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. The HMP7 is part of the Indigo product family and compatible with Indigo 200 Series Host Devices and free Insight PC Software.
Key Benefits
Proven Vaisala HUMICAP performance
Vaisala is the original innovator of the thin-film capacitive humidity measurement technology, which has now become the industry standard in humidity measurement.
No condensation at extreme humidity
Probe heating functionality heats up the whole probe head. When probe temperature is heated above dew point temperature, condensation on the probe can be avoided.
Flexible connectivity
The probe is plug and play compatible with Vaisala Indigo host devices, can be used as a standalone digital Modbus RTU transmitter, or connected to Vaisala Insight™ PC Software.
