Main Advantages:

Proven Vaisala HUMICAP performance

Vaisala has thin-film capacitive humidity measurement technology, which is widely accepted and commonly used in the field of humidity measurement, and is also widely followed in the field of humidity measurement standards.

There is no condensation under severe humidity conditions

The probe heating function increases the temperature of the entire probe. When the probe temperature is higher than the dew point temperature, condensation on the probe can be avoided.

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.
