Vaisala HUMICAP Humidity and Temperature Probe HMP5 is designed for high-temperature applications such as baking ovens, pasta dryers, ceramics, and industrial drying kilns where measurement performance and chemical tolerance are essential. The HMP5 is part of the Indigo product family and compatible with Indigo500 and Indigo200 series transmitters and free Insight PC Software.
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.
The probe is plug and play compatible with Vaisala Indigo series transmitters, can be used as a standalone digital Modbus RTU transmitter, or connected to Vaisala Insight™ PC Software.
