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.

Chemical purge minimizes effects of contaminants

In environments with high concentrations of chemicals and cleaning agents, the chemical purge option helps to maintain measurement accuracy between calibration intervals.

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.
