Trotec T250C

CODE: MOIS TROTEC T250C

The Trotec T250C is a high quality German manufactured handheld thermo-hygrometer capable of measuring the relative humidity content of a concrete slab.
It also includes a built-in laser pyrometer and a dew point alarm which allows the T250C to measure surface temperature of the concrete or surface.


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 Bulletins 330 and 515.

The only way to perform a humidity measurement is with a Hygrometer.
The T250C 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 1 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 2 left).

Note: For both methods, it is important to let the T250C aclimatise to the temperature inside the humidity box or sleeve to attain the correct values.

The T250C can also measure the surface temperature (IR laser mode) air temperature and dew point temperature.

A wide range of accessories including humidity sleeves, humidity boxes, soft and hard carry cases are available for the T250C.

This concrete-hygrometer is available for HIRE.

The T2000S can be used as a scanning non-invasive meter (see Image 1 left).
This function 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).

Note: For both methods, it is important to let the T2000S aclimatise to the temperature inside the humidity box or sleeve to attain the correct values.

With the correct sensors and probes, the T2000S can also measure timber moisture, air, liquid, surface & dew point temperature, air velocity etc.

A wide range of accessories including humidity sleeves, humidity boxes, temperature sensors and probes, sliding hammer electrodes, soft and hard carry cases are available for the T2000S.
