Vaisala Dew Point Transmitters for High Temperature Applications – DMT345 and DMT346


The Vaisala DRYCAP® Dewpoint Transmitters DMT345 and DMT346 are designed for humidity measurement in industrial drying applications with particularly high temperatures. The high temperature tolerance of the sensor allows direct measurement from hot process without the need for a sampling system and sample conditioning. The wide dynamic rage of the measurement in DMT345 and DMT346 is unique: Measurements can be made from -40 °C frost point up to +100 °C dew point, with dry-bulb temperatures ranging up to 350 °C.



Both transmitters incorporate the Vaisala DRYCAP® sensor, which is accurate, reliable, and stable. The sensor is condensation-resistant and is immune to particulate contamination, oil vapor, and most chemicals. The DRYCAP® sensor is notable for its swift response time and rapid recovery after getting wet.

Vaisala Indigo Family

Discover the modular Indigo

The Vaisala Indigo family is a customizable instrument platform designed to improve process measurements. The Indigo family’s key feature is modularity. It contains a selection of transmitters, interchangeable smart probes that measure various parameters, and software for easy interfacing and monitoring of data. Choose any probe and connect it with any of the transmitters, or integrate the probes into other systems. The Indigo platform is built on top of Vaisala’s self-produced, core sensor technologies.

Whether you measure humidity, temperature, dew point, moisture in oil, carbon dioxide, barometric pressure, or vaporized hydrogen peroxide, the accuracy and long-term stability of Indigo-compatible probes are in the class of their own. The probes deliver repeatable measurement with high resolution, providing you with data that you can rely on, which helps you to make better decisions – over the long term.


Indigo transmitters

Vaisala Indigo transmitters offer many features that complement Indigocompatible smart probes. They enable real-time data visualization and access to probe configurations. They also offer additional connectivity, supply voltage, and wiring options compared to using a stand-alone smart probe.

  • Indigo500 series – a robust transmitter with features including dual probe support, power over Ethernet, a robust metal enclosure, and touchscreen display.
  • Indigo200 series – a transmitter with single probe support, analog, digital, and relay outputs, a modern graphical or numeric display, and wireless access via a nearby smartphone or PC.
