Indigo ecosystem features

The new Indigo platform is built on the same measurement technology as its predecessor, the HMT330 series. The most significant and widely desired feature of the Indigo platform is the interchangeability of the smart probes. Many functionalities that were traditionally located inside the transmitter are now built into the smart probe instead, allowing for field swapping and cross-functional configurations.

Comprehensive range of measurement parameters

  • humidity and temperature
  • dew point
  • moisture in oil
  • carbon dioxide (CO2)
  • vaporized hydrogen peroxide (H2O2)
  • barometric pressure
