e Vaisala DRYCAP®

Hand-Held Dewpoint Meter

DM70 oers accurate

and fast measurement

for industrial dewpoint

applications, such as

compressed air, metal

treatment and plastics

drying.

DM70 Hand-Held Dewpoint Meter

for Spot-Checking Applications

e Vaisala DRYCAP® Hand-Held

Dewpoint Meter DM70 measures

dewpoint temperature accurately

over a wide measurement range. e

probe may be inserted directly into

pressurized processes, and it responds

rapidly from ambient to process

conditions. e sensor withstands

condensation and fully recovers from

getting wet.

Three DMP74 probe models

ree probe models, all with auto-

calibration, are available. e A and

B models are both general purpose

probes. e A model is for dewpoint

range from -40 to +60 °C T

, and the B

model for -60 to +20 °C T

. e C model

is specically developed for SF

gas with

a dewpoint range down to -50 °C T

e B and C probe models have an

additional Sensor Purge feature. e

Sensor Purge heats and dries the sensor,

making the response from ambient

to dry conditions exceptionally fast.

is facilitates rapid spot checking

measurements in low dewpoints.

Low maintenance due to

innovative autocalibration

e DM70 is tted with the Vaisala

DRYCAP® Sensor. e sensor provides

reliable and high-performance

dewpoint measurement with

revolutionary long-term stability. e

patented autocalibration procedure

detects on-line possible measurement

inaccuracies and automatically

corrects dry-end drift in the calibration

curve. ese advanced features provide

a long calibration interval and low

maintenance cost.

e meter is calibrated in the factory

against internationally traceable

standards and delivered with a

calibration certicate. e DM70 can

also be sent to a Vaisala Service Center

for a traceable recalibration.

Easy-to-use user interface

e 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 xed

Features/Beneﬁts

• Designed for industrial spot

checking and eld calibration

• ree models: accurate

measurement ranges from -60 to

+60 °C (-76 ... +140 °F)

• Vaisala DRYCAP® Sensor with

patented autocalibration function

• Low maintenance need due to

superior long-term stability

• Sensor withstands condensation

• Fast response, enhanced by Sensor

Purge option

• Easy-to-use user interface

• Data can be logged and transferred

to a PC via MI70 Link software

• Compact, small and light

• NIST traceable (certicate

included)

Vaisala dewpoint transmitters, like the

DMT242, DMT142 and DMT340.

Various display variables

e 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.

e graphical display helps the user to know

when the dewpoint plateau is reached.
