The Vaisala HMP5 relative humidity and temperature probe is designed for high-temperature applications, up to 356°F (180°C), such as baking ovens, pasta dryers and industrial drying kilns, where measurement performance and chemical tolerance are essential. The HMP5's IP66-rated housing makes it suitable for indoor or outdoor use.
With a HUMICAP R2 composite sensor, the HMP5 offers measurement ranges of 0 to 100% relative humidity and temperature from -94 to +356°F (-70 to 180°C). Vaisala's thin-film capacitive technology allows for RH accuracy up to 0.8% and the Pt100 RTD Class F0.1 IEC 60751 temperature sensor provides accuracy up to 0.18°F (0.1°C).
The Vaisala HMP5 is also part of the Indigo product family and compatible with Indigo 201 and 202 transmitters. The HMP5 is plug and play compatible with Vaisala's Indigo series of transmitters, or it can be used as a standalone digital Modbus RTU transmitter over RS-485 serial bus. If analog output is required the probe must be paired with an Indigo 201 transmitter.
