  • Vaisala DRYCAP Sensor
  • NIST traceable certificate
  • Sampling system compatible

The Vaisala DM70 DRYCAP hand-held dewpoint meter measures dewpoint temperature accurately over a wide measurement range. The probe may be inserted directly into pressurized processes, and it reponds rapidly from ambient to process conditions. The sensor withstands condensation and fully recovers from getting wet.

The Vaisala DM70 is calibrated in the factory against internationally traceable standards and delivered with a calibration certificate. The user interface is menu-based with a clear graphical LCD display with data logger function. IT can also be used as a tool for reading the output of fixed Vaisala dewpoint transmitters like the DMT242 and DMT340 series.

The Vaisala DM70 has a MI70 Link Windows software program. In combination with a USB connection cable it's an excellent tool for transferring logged and real time measurement data from the DM70 to a PC.
