Data Storage Functions
When concise and accurate environmental readings
need to be reported, the MMS Plus gets the job
done. The ability to record readings instantly at the
push of a button, and to continuously log when
left on site, makes this instrument ideal for many
applications including:
• Building survey
• Fire and flood restoration
• Concrete floor moisture measurement
• Indoor air quality
• Environmental health

Concrete Floor Moisture
Measurement
MMS2 can be used for measuring equilibrium
relative humidity directly in concrete slabs.
Protimeter pioneered this more accurate method,
which includes drilling holes in the concrete,
inserting a humidity sleeve and measuring the
equilibrium humidity in the concrete. If excessive
moisture is found, simply replace the sleeve cap for
future retesting. This method also permits normal
construction without disturbing the test surface.
A small hole is drilled in the concrete. Next, a
humidity sleeve is inserted and capped flush with
the floor. The relative humidity of the air in the
test hole is now at the same moisture level as the
concrete around it. Flooring product manufacturers
normally recommend RH readings between 75%
and 85% depending on the permeability of the
product being installed.
Readings from multiple Hygrosticks can be taken
and recorded with ease. Humidity readings can be
taken with the use of humidity sleeves or humidity
box. Hygrosticks, not Humisticks, should be used
for this test.
Humidity Probe Options
The MMS Plus may be used with three styles of
interchangeable humidity probe, the Hygrostick,
the Quikstick and the Quikstick ST. The Hygrostick
(grey POL4750) can be used for high moisture
applications such as concrete measurement.
Quikstick (black POL8750) is a general purpose,
fast-responding full range sensor.
Quikstick ST POL78751, standard with all
MMS2 kits and with the same performance
as the standard Quikstick. A Quikstick ST can
remain connected to the MMS 2 while using
the pins.
Hygrostick part number POL4750, for high
moisture applications.
