Humimeter GF2 Building Moisture Meter

 

 

humimeter GF2

Professional non-destructive moisture meter for concrete, screed, bricks, plasterboard, wood, air humidity, temperature (Infrared) and many other materials and application areas.  

 

Applications

The Humimeter GF2 building moisture meter is a professional and versatile building moisture meter which can be extended with various sensors to match your individual needs. As the GF2 offers such a wide variety of functions we recommend some well proven configurations for popular tasks in the building industry. Especially notable is the blazingly fast nondestructive measurement of floor screed without using the tedious CM method.

The GF2 building moisture meter is able to perform lots of measurements relevant for the building industry including: building moisture, air humidity, indoor climate, dew point, equilibrium moisture content, air and surface temperature as well as long-term recording of climate data, incl. material moisture sensor. Optionally available external air humidity and infrared temperature sensors, PC software for data archiving and graphic display of climate data.

Handling / measuring procedure

After switching on the unit, select the characteristic curve corresponding to the material to be measured on the measuring unit (for example screed).
Make sure that the surface of the screed is smooth (no protruding parts or impurities) so that the sensor surface of the measuring device can rest flat on the screed. Otherwise, the surface can be scraped off with a spatula or clean chisel and then swept with a broom.
Now the measuring device can be placed on the screed and pressed onto the surface with moderate pressure. The water content is immediately shown on the display. 

By effecting various measurements in different areas of the screed, the average water content can be determined immediately. It is also possible to detect moist spots. 

The measuring values can be stored on the device, further information like batch number can be added. Via the optional USB interface, the measuring values can be transferred to a PC, and via LogMemorizer ® PC software the data can be archived, exported, processed or printed out.

CM measurement

Many people still use a CM measurement when they want to measure the screed moisture. However, this method of determining the moisture content of the screed offers hardly any advantages and mainly has major disadvantages.  On the one hand, CM measurement is expensive and impractical to use, which does not simplify the daily routine on construction sites. On the other hand, only a small area can be investigated with CM measurement, which requires a lot of work. Another factor is the inaccuracy of CM measurement, because who can confirm that the conversion from CM measurement to water content is correct?

To avoid all these problems, the humimeter GF2 moisture meter was developed to determine screed moisture without CM measurement. The fast and non-destructive measurement allows a large area to be tested in a short time by placing the moisture meter on the floor and reading the water content from the display. Therefore, you can use the GF2 moisture meter to determine the moisture content of your screed without the need for expensive CM measurements.
