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.
