Relative Humidity and Temperature Probe HMP4
Relative Humidity and Temperature Probe HMP4
Vaisala HUMICAP® Humidity and Temperature Probe HMP4 is designed for high-pressure applications such as compressed air systems in maritime, breathing air, and industrial applications, where measurement performance and chemical tolerance are essential. The HMP4 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.
Chemical Purge Minimizes Effects of Contaminants
In environments with high concentrations of chemicals and cleaning agents, the chemical purge option helps to maintain measurement accuracy between calibration intervals.
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.
