Features/Benefits Designed for industrial spot checking and field calibration Օ hree models: accurate measurement ranges from -60 to +60 °C (-76 ... +140 °F) Vaisala DRYCAP® Sensor with patented autocalibration fonction Օ Low maintenance need due to superior long-term stability Sensor withstands condensation Օ Fast response, enhanced by Sensor Purge option Easy-to-use user interface Օ Data can be logged and transferred to a PC via MI70 Link software Compact, small and light Օ NIST traceable (certificate included) he Vaisala DRYCAP® Hand-Held Dewpoint Meter DM70 measures dewpoint 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. Three DMP74 probe models Tree probe models, all with auto-calibration, are available. Te A and B models are both general purpose probes. Te A model is for dewpoint range from -40 to +60 °C Td, and the B model for -60 to +20 °C T. he C model d is specifically developed for SF6 gas with a dewpoint range down to -50 °C Td. he B and C probe models have an additional Sensor Purge feature. he Sensor Purge heats and dries the sensor, making the response from ambient to dry conditions exceptionally fast. his facilitates rapid spot checking measurements in low dewpoints. Low maintenance due to innovative autocalibration he DM70 is itted with the Vaisala DRYCAP® Sensor. he sensor provides reliable and high-performance dewpoint measurement with revolutionary long-term stability. he patented autocalibration procedure detects on-line possible measurement inaccuracies and automatically corrects dry-end drift in the calibration curve. hese advanced features provide a long calibration interval and low maintenance cost. he meter is calibrated in the factory against internationally traceable standards and delivered with a calibration certiicate. he DM70 can also be sent to a Vaisala Service Center for a traceable recalibration. Easy-to-use user interface he DM70 has a versatile and easy-to-use, menu-based user interface and a clear graphical LCD display with data-logger function. It can also be used as a tool for reading the output of ixed Vaisala dewpoint transmitters, like the DMT242, DMT142 and DMT340. Various display variables he DM70 displays one to three parameters at a time, either numerically or graphically. Several humidity units can be selected. In addition, the DM70 includes conversion from gas pressure dewpoint to ambient pressure dewpoint. An analog output is also available. he graphical display helps the user to know when the dewpoint plateau is reached. 70 Vaisala Instruments Catalog 2009 Ref. B210768EN rev. A

e 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. > e DSS70A is designed to provide dewpoint sampling exibility. 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 lter to remove particulate...
