The new Vaisala Humicap humidity and temperature probes HMP4, HMP5, HMP7, HMP8 and the Vaisala temperature probe TMP1 are part of Vaisala's Indigo product family and will complement the Indigo family members GMP250 series and the HPP272.
The newly launched probes share also functionalities like chemical purge and sensor heating. The HMP7 features also warmed probe technology, which enables accurate measurements highly condensing environments. All the HMP probes are equipped with the new Vaisala Humicap R2 composite sensor. It gives corrosion resistance to the sensor particularly in acidic environments. All of the probes are also resistant to dust and most chemicals, and their smooth surface is easy to clean.
The new Indigo family members are compatible with the free Vaisala Insight PC software, which allows convenient setup, diagnostics and field calibration. The probes can also be used without Indigo host device through Modbus protocol.
The first shipments of the probes are scheduled to start in December.
