Relative Humidity and Temperature Probe HMP7 for high humidities Image 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 Indigo500 and Indigo200 series transmitters and free Insight PC Software. Click here to download bid specs for USA. Buy Now Datasheet Contact us 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) Vapor and pressure proof construction Probe and sensor warming functions minimize condensation on probe Sensor purge provides superior chemical resistance Plug & play compatible with Indigo™ series of transmitters Modbus RTU over RS-485 Traceable calibration certificate: 6 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. 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 series transmitters, can be used as a standalone digital Modbus RTU transmitter, or connected to Vaisala Insight™ PC Software.

What to take into account when adjusting process? Register to watch Customer case Malting process improved using Indigo500 with HMP7 and TMP1 probes As one of the world’s leading suppliers of high quality malt products, Viking Malt has investigated the advantages of continuous humidity monitoring inside the malting process at its facility using Vaisala’s Indigo520 and HMP7 and TMP1 probes. Learn more Customer case Optimized drying process helps Isolava cut energy consumption and improve end-product quality Isolava began a project to optimize the drying process, led by Project Engineer Peter Vaneyghen. The first step was to install humidity sensors in the dryer in order to get a better understanding of the dynamics of the drying process. The consumption of natural gas alone has decreased by some 20% and the annual savings across all ten dryers add up to hundreds of thousands of euros.

Unlike in the past when measurement probes could not be used on their own, the new wave of smart measurement probes can operate independently without additional transmitters. Learn more Blog Measuring humidity in condensing environments Taking measurements in environments with high relative humidity (over 90%) is always a challenge because the environment is so close to saturation.
