Vaisala DM70 Portable Dewpoint Meter

The Vaisala DRYCAP® Hand-Held, Portable Dewpoint meter DM70 is designed for demanding spot-checking applications of dewpoint.  The DM70 consists of an MI70 Vaisala indicator and is supplied with one of three probe options:

 

– DMP74A -40…+60°C Td
– DMP74B -60…+20°C Td
– DMP74C -50…+20°C Td (for SF6 gas)

 

Dewpoint measurement is particularly common in compressed air measurement to monitor the efficiency of driers.  The Vaisala DM70 unit maybe supplied with a sampling cell for this purpose.  Additionally, Fluidic offer a range of fixed Dewpoint instrumentation from Vaisala for continuous measurement.  The DM70 is commonly used as a calibration reference for fixed devices: connection cables are available for most Vaisala transmitters

Product Description

The Vaisala DRYCAP® Hand-Held, Portable Dewpoint meter DM70 is designed for demanding spot-checking applications of dewpoint.  The DM70 consists of an MI70 Vaisala indicator and is supplied with one of three probe options:

  • DMP74A -40…+60°C Td
  • DMP74B -60…+20°C Td
  • DMP74C -50…+20°C Td (for SF6 gas)

 

The MI70 indicator will accept 2x probes to run simultaneously, including a range of RH&T probes (from the HM70 range) and carbon dioxide probes (from the GM70) range.  The MI70 indicator includes a datalogging facility (2700 datapoints memory) and can be supplied with Windows® Software MI70LINK with USB interface for graphing of collected information.
