Description
Product Details
Miniature Probe Head
The 5 mm diameter probe head contains a new-generation HUMICAP® sensor that provides industry-standard humidity measurement performance. The HMP9 is a stable instrument with a fast response time and low hysteresis in a wide range of applications.
Minimized Effects of Contaminants
In environments with high concentrations of chemicals and cleaning agents, the chemical purge option heats the sensor to remove harmful chemicals, helping to maintain measurement accuracy between calibration intervals. The chemical purge process can be initiated manually or programmed to take place at set intervals.
Flexible Connectivity
The probe is plug-and-play compatible with the Vaisala Indigo series transmitters, which offers a variety of connectivity options through analog signals or digital outputs, configurable relays, and a wireless (WLAN) configuration interface. It can also be used as a standalone digital Modbus RTU transmitter over RS-485 serial bus. For easy-to-use access to field calibration, device analytics, and configuration functionality, the probe can be connected to Vaisala Insight software (for Windows® 7, 8.1, and 10).
