8.1.4 Field Check Using DM70 Handheld Dew Point Meter
Vaisala recommends the following equipment for field checking:
• A fully charged MI70 indicator (the measurement display that is included in the DM70
package).
• A calibrated reference probe that is suitable for the intended measurement environment
and dew point range. The DMP74B probe is recommended for checking the dew point
temperature measurement accuracy.
• You also need a connection cable (Vaisala order code 219980SP) to connect the DMT143
to the MI70 indicator.
