Note that the HMT330 series is being discontinued. It is replaced by Indigo family products. Do not specify HMT330 for new projects, instead view Indigo transmitters and probes that are also designed for use in demanding applications.
Measure humidity in harsh environments with the instrument you can depend on. The Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMT330 is designed for demanding industrial applications where stable measurements and extensive customization are essential.
Looking for HMT330 performance with interchangeable probes and a transmitter supporting two probes? View Indigo family. To learn more about the differences between HMT330 and the Indigo platform, view this comparison sheet for details.
Interchangeable smart probes, robust transmitters, and Vaisala Insight software create a strong ecosystem to ensure energy efficiency, safety, and end-product quality in your operations. The modular plug-and-play design makes Indigo family probes and transmitters easy to install, use, and maintain.
HMT331 for wall mounting is now HMP1 probe + INDIGO500 transmitter
HMT333 for duct mounting and tight spaces is now HMP3 and HMP9 probes + INDIGO500 transmitter
HMT334 for high pressures up to 100 bar and vacuum conditions is now HMP4 + INDIGO500 transmitter
HMT335 for high temperatures is now HMP5 + INDIGO500 transmitter
HMT337 for high humidity and meteorological applications is now HMP7 + INDIGO500 transmitter
HMT338 for pressurized pipelines up to 40 bar is now HMP8 + INDIGO500 transmitter

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.
