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.

What is a smart measurement probe and what makes it special?
Environmental measurement devices are also becoming smart. Unlike in the past when measurement probes could not be used on their own, the new wave of smart measurement probes can operate independently without additional transmitters.
