DM70 Handheld Dew Point Meter

For spot-checking applications

Features

• Designed for industrial spot-

checking and field calibration

• Three models: accurate

measurement ranges from

−60 to +60 °C (−76 ... +140 °F)

• Vaisala DRYCAPâ sensor with

unique autocalibration function

• Sensor withstands condensation

• Data can be logged and

transferred to a PC via MI70 Link

software

• Traceable calibration (certificate

included)

• Fast response, enhanced by

sensor purge option

• Variety of sampling cell options

for connection to pressurized

processes

Vaisala DRYCAPâ Handheld Dew Point Meter DM70 offers accurate and fast

measurement for industrial dew point applications, such as compressed air, metal

treatment, and plastics drying.

Benefits

• Compact, small and light

• Intuitive user interface

• Low maintenance need due to

superior long-term stability

• Sensor withstands condensation

and fully recovers from getting

wet

DM70 measures dew point 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 DM70 meter is

suitable for direct process dew point

measurement in a wide temperature and

pressure range. For more demanding

applications, DM70 can be used with

Vaisala sampling cells or with Vaisala

DRYCAPâ Sampling System DSS70A.

Vaisala DRYCAPâ technology

DM70 is fitted with the Vaisala DRYCAPâ

sensor. The sensor provides reliable,

stable and high-performance dew point

measurement. Autocalibration detects

on-line possible measurement

inaccuracies and automatically corrects

dry-end drift in the calibration curve.

Three probes to choose from

Three probe models, all with

autocalibration, are available. The

DMP74A and DMP74B models are both

general purpose probes. The DMP74C

model is specifically developed for SF6

gas. The B and C probe models have an

additional sensor purge feature that

heats and dries the sensor, making the

response from ambient to dry conditions

exceptionally fast.

Intuitive user interface

DM70 has a versatile and easy-to-use,

menu-based user interface, a clear

graphical LCD display, and datalogging

capability. It can also be used as a tool

for reading the output of fixed Vaisala

dew point transmitters, such as DMT242,

DMT132, DMT143, DMT152, and DMT340.

DM70 displays one to three parameters

at a time, either numerically or

graphically. Several humidity units can be

selected. In addition, DM70 includes

conversion from gas pressure dew point

to ambient pressure dew point. An

analog output is also available.

MI70 Link Windowsâ software

The optional Vaisala MI70 Link Windowsâ

software and the USB connection cable

form a practical tool for transferring

logged data and real time measurement

data from DM70 to a PC.
