Vaisala DM70 DRYCAP Hand-Held Dewpoint Meter

Vaisala DM70 DRYCAP® Hand-Held Dewpoint Meter

The Vaisala DRYCAP® Hand-Held Dewpoint Meter DM70 offers accurate and fast measurement for industrial dewpoint applications, such as compressed air, metal treatment and plastics drying.   

The probe has an additional Sensor Purge feature. The Sensor Purge heats and dries the sensor, making the response from ambient to dry conditions exceptionally fast.  This facilitates rapid spot checking measurements in low dewpoints.

                           

Features:

• Designed for industrial spot checking and field calibration
• Vaisala DRYCAP® Sensor with patented autocalibration function
• Low maintenance need due to superior long-term stability
• Sensor withstands condensation
• Fast response, enhanced by Sensor Purge option
• Easy-to-use user interface
• Data can be logged and transferred to a PC via MI70 Link software
• Compact, small and light

DSS70A Portable Sampling System

The DSS70A is designed to provide dewpoint sampling flexibility. For processes at atmospheric pressure, a battery powered pump is used to extract a gas sample. For pressurized processes up to 20 bar, the sample is measured at process pressure and then reduced to atmospheric pressure for venting or re-direction, bypassing the pump. In all cases, the sample gas passes through a filter to remove particulate contamination before measurement. Flow through the system is controlled and monitored with a needle valve and flow meter.  The DSS70A is easily connected to an appropriate sample point with tubing (typically 1/4" or 6 mm). The measured dewpoint must be below ambient temperature to avoid condensation in the system. Gas temperatures higher than +40 C (+104 F) should be cooled with a short PTFE or stainless steel tube prior to entering the DSS70A.
