Pressure probe HUMICAP®

temperatureambient aircalibration

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 Indigo500 and Indigo200 series transmitters and free Insight PC Software. Features RH accuracy up to 0.8 %RH, Temperature accuracy up to 0.1 °C (0.18 °F) Temperature measurement range -70 ... +180 °C (-94 ... +356 °F) Sensor purge provides superior chemical resistance Modbus RTU over RS-485 Plug & play compatible with Indigo™ series of transmitters Traceable calibration certificate: 5 points for humidity, 1 point for temperature 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 series transmitters, can be used as a standalone digital Modbus RTU transmitter, or connected to Vaisala Insight™ PC Software.
