The Indigo family of smart sensors and transmitters, from Vaisala, has been expanded with some newly released humidity probes. The five new probes can be used with an Indigo host device or another using Modbus protocol. Previously available sensors measured concentrations of gaseous carbon dioxide and hydrogen peroxide. The new offering expands the Indigo functionality into humidity measurement, a mainstay of Vaisala for many years. Humidity can now be measured in:

  • Pressurized or high pressure environments, up to 100 bars, with two probe offerings covering differing pressure ranges
  • High temperature ovens and similar applications
  • High humidity applications where probe heating is required
There is also a new version available for temperature measurement. 

The Indigo family of sensors and host devices are interchangeable, and all can interface with Vaisala's Insight PC software.
