Dew Point and Temperature Meter Series DMT340

for demanding low humidity conditions

Note that the DMT340 series is being discontinued. It is replaced by Indigo family products. Do not specify DMT340 for new projects, instead view Indigo transmitters and probes that are also designed for use in demanding applications.

Condensation-resistant DMT340 is designed for industrial low-humidity applications such as industrial drying, compressed air systems, semiconductor industry, dry rooms, baking ovens, and metal heat treatment to provide accurate and reliable measurement.

DMT340 is compatible with the Vaisala DRYCAP® Handheld Dew Point Meter DM70.

Key benefits

Choose the probe suitable for your needs

Five different probe types designed to meet various requirements.

Easy maintenance

The Vaisala DRYCAP® sensor is immune to particulate contamination, water condensation, oil vapor, and most chemicals.

Stable measurement

The auto-calibration feature allows the transmitter to perform calibration and adjustment by itself while the measured process is running.

Customer case

Optimized drying process helps Isolava cut energy consumption and improve end-product quality

Isolava began a project to optimize the drying process, led by Project Engineer Peter Vaneyghen. The first step was to install humidity sensors in the dryer in order to get a better understanding of the dynamics of the drying process. The consumption of natural gas alone has decreased by some 20% and the annual savings across all ten dryers add up to hundreds of thousands of euros.
