Main Advantages:

Proven Vaisala HUMICAP performance

Vaisala is the originator of thin film capacitive humidity measurement technology, which has become the industry standard in the field of humidity measurement.

Chemical removal greatly reduces the impact of contaminants

In environments with high concentrations of chemicals and cleaners, the chemical removal option helps maintain measurement accuracy between calibration cycles.

Flexible connection

The probe is plug and play compatible with the Vaisala Indigo host device and can be used as a standalone digital Modbus RTU transmitter or connected to the Vaisala Insight? PC software.
