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

Rel

H2O/WME

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.

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.

Hygrostick part number POL4750, for high

moisture applications.
