​The Vaisala DRYCAP® Hand-Held Dewpoint Meter DM70 measures dew point temperature accurately over a wide measurement range. The probe may be inserted directly into pressurized processes, and it responds rapidly from ambient to process conditions. The sensor withstands condensation and fully recovers from getting wet. The DM70 can also be used as a tool for reading the output of fixed Vaisala dew point transmitters, like the DMT132, DMT143, DMT152, and DMT340.

Where direct measurement is difficult, the DM70 can be used with Vaisala's sampling cells, or with Vaisala DRYCAP Portable Sampling System DSS70A.
