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.
