Protimeter MMS2 Moisture Meter

  • The latest Protimeter technology in one intuitive, robust, and fully efficient design
  • Comprehensive building moisture diagnostics on an easy-to-use instrument
  • Fast responding hygrometer speeds up building surveys
  • No need to plug in multiple accessories

The Protimeter MMS2 is a multi function temperature, humidity, moisture locating AND moisture measurement tool, used primarily in the flooring industry.

It can be used to scan and locate mositure related problems PLUS measure the moisture content of timber and concrete.

Following on from the original MMS, the new MMS2 now includes an infrared laser thermometer for measuring surface temperature as well as data logging functionality - both manual log and automatic.

Moisture Measurement of Concrete Floors New Zealand Flooring Standards require concrete floors to have a relative humidity level of no more than 75 % before floor coverings can be installed.

Simple non-invasive "scanning" capacitance meters either do not provide a humidity RH reading OR are simply not an accurate method of "measuring" concrete moisture. *More information can be found by referring to the NZ Flooring Industry Standards AS/NZS 2455 and AS/NZS 1884 and BRANZ Bulletin and 585.



The MMS2 has a scanning non-invasive mode (see Image 1 left). This mode is used for locating or testing the concrete for moisture. If a measurement or more accurate data is required, a measurement test must be performed (as described below).

The only way to perform a humidity measurement is with a Hygrometer. The MMS2 is a hygrometer.

For a non destructive method of measuring, the hygrometer can be used with a humidity box. This box (with a small cavity on the underneath side, and a plugged hole in the side) is sealed to the top of the concrete slab and left, typically, for a period of 24-36 hours. Because the cavity space on the underneth of box is less dense than the concrete, the movement of moisture occurs from the concrete into this space. After the alotted time period, the plug from the side is removed and the hygrometer is inserted into this hole to measure the RH inside the cavity within the humidity box (see Image 2 left).. Often 2 or 3 boxes are used across a whole slab. The average reading is then taken.

For an invasive deeper method of measuring, holes can be drilled into the concrete and plastic sleeves can be inserted into the slab. The sleeve, approx. 16mm in diameter, is inserted into the drilled hole, then capped and left, typically for a period of 24-36 hours. Several sleeves are inserted into the concrete to attain areas over a greater area on the concrete slab when compared to the humidity box option above. Because the sleeve is perforated and the space inside the sleeve is less dense than the surrounding concrete, the movement of moisture occurs from the concrete into this space. After the alotted time period, the cap is removed and the hygrometer is inserted into this sleeve to measure the RH within the concrete slab (see Image 3 left).

Note: For both methods, it is important to let the MMS2 aclimatise to the temperature inside the humidity box or sleeve to attain the correct values.

With the correct attachments, the MMS2 can also measure the % of wood moisture, air, surface and dew point temperature, grains per pound etc.

A wide range of accessories including humidity sleeves, humidity boxes, sliding hammer electrodes, hard carry cases are available for the MMS2.
