DM70 Hand-held Dewpoint and Temperature Meter set with carrying case for Desiccant Dryers, -60 to +20°C Dewpoint


The Vaisala DRYCAP® Hand-Held Dewpoint Meter DM70 measures dew point and temperature accurately over a wide measurement range. The probe may be inserted directly into pressurized processes up to 20 bar (290 psi), and it responds rapidly from ambient to process conditions. This DM70 model is especially suitable for checking the operation of desiccant dryers in compressed air systems.

With the DM70 you can also field check the DMT143 dewpoint tranmitters

The DM70 also supports the use of Vaisala's humidity, carbon dioxide and moisture in oil probes, making it a versatile investment applicable to several multi-parameter applications. Two probes can simultaneously be connected to the DM70.

The MI70 Link Windows® software and the USB connection cable form a practical mean for transferring logged and real time measurement data from the DM70 to a PC. Included in the package
