MM70 Hand-Held Moisture and Temperature
Meter for Spot-Checking in Oil
The Vaisala HUMICAP
®
Hand-held
Moisture Meter for Oil MM70 enables
reliable detection of moisture in oil.
In-Line Process Checking
Through Ball Valve
The probe can be inserted directly
into the process pipe through a ball
valve without draining the oil in the
system.
Water Activity
Measurement
The MM70 measures moisture in oil
in terms of the water activity (aw)
and temperature (T). Water activity
directly indicates whether there is
a risk of free water formation. The
measurement is independent of oil
type, age and temperature.
PPM Calculation Included
The MM70 has an embedded model
for expressing moisture as ppm in
mineral transformer oil. The customer
can enter up to three other oil models
into the meter’s memory.
The MM70 is an ideal
tool for the preventive
maintenance of oil-filled
systems. The water
activity measurement
indicates the margin to
free water formation,
which causes severe
problems in lubrication
systems.
Numerical and
Graphical Display
The MM70 features a multilingual,
menu-based user interface and a
backlit LCD display. The measurement
parameters can be numerically and
graphically displayed and logged
into the meter's memory at the same
time. An analog output option is also
available.
Connection to PC
The optional MI70 Link Windows
®
software in combination with a
USB connection cable is used to
transfer logged data and real time
measurement data from the MM70
to a PC.
Proven Vaisala HUMICAP®
Technology
The MM70 incorporates the latest
generation of the Vaisala HUMICAP
®
Sensor, developed for demanding
moisture measurements in liquid
hydrocarbons. The sensor’s excellent
chemical tolerance provides accurate
and reliable measurement over the
measurement range.
Speedy Service -
Once a Year
The meter can be recalibrated
by sending the probe to Vaisala
Service, or customers can calibrate
the instrument themselves using a
standard relative humidity calibration.
Multi-Probe Operation
One or two probes can be connected
simultaneously. Maintenance teams
can use additional Vaisala dew point
or relative humidity probes for other
tasks. For example, a dew point probe
is ideal for checking the moisture
inside washed and dried oil tanks.
