Professional moisture meter humimeter GF2
Thanks to a large number of sensors, the GF2 moisture meter enables many measurements: residual moisture and readiness for covering of concrete, moisture of building materials such as drywall, wood, concrete and bricks - as well as humidity and temperature.
Areas of application of the versatile moisture meter for buildings, walls and floors:
Since the humimeter GF2 is intended for professionals, the device covers many areas of application and is also the perfect alternative to the time-consuming CM measurement, because even large screed areas can be examined in just a few minutes:
- Determine the readiness for covering (degree of drying) of the screed (e.g. for parquet flooring).
- Inspection of damp spots, e.g. in masonry, insulation, wood, drywall, concrete
- Measurement of surface temperature (infrared)
- Measurement of humidity and temperature
- Measure wood moisture
Simply measure the readiness for covering and the moisture content of the screed:
The humimeter GF2 is an excellent moisture meter for screeds. It enables a quick and accurate check of the readiness for covering of screed and other building materials. With the capacitive moisture sensor built into the measuring device, a representative point for carrying out a CRH or CM measurement can be found in a very short time by means of a grid measurement, in order to then check the readiness for covering. The measuring device also uses the CRH method (CRH = corresponding relative humidity) to measure the dryness of the screed.
In addition to being able to measure the screed moisture, the measuring device is also suitable for determining the moisture in drywall and other building materials. On the underside of the device is a capacitive moisture sensor for non-destructive measurement of concrete, screed, plasterboard, aerated concrete (Ytong), concrete bricks, clinker bricks, insulating materials and much more. installed.
The capacitive sensor is ideally suited for monitoring drying processes in new buildings or during renovation work or for determining damp spots, e.g. leaks, wall or floor moisture.
GF2 offers a real alternative to CM measurement (calcium carbide method)
The CM measurement is still widely used in the construction industry. On the one hand, the CM measurement is expensive because it is time-consuming and impractical to use. On the other hand, only a small selective area can be examined with the CM measurement. Another factor is the inaccuracy of the CM measurement: different screed recipes, additives and chemicals sometimes have a strong influence on the CM measurement.
To avoid all these problems, the humimeter GF2 building moisture meter was developed to determine screed moisture. The fast and non-destructive measurement enables a large area to be examined in a short time. In this way, entire single-family houses can be measured non-destructively at many measuring points in just a few minutes - room by room.
If a CM measurement is nevertheless required, a combination of the two measurement methods can be used: using a grid measurement, the GF2 can be used to determine a representative point for carrying out the required CM measurement in a very short time.
The measuring device is adjusted after calibration to the reference method EN ISO 12570.
The humimeter GF2 supports numerous measurement statistics for building moisture, air humidity, room climate, dew point, equilibrium moisture, air and surface temperature as well as long-term climate data recording including material moisture sensor. This requires external humidity, temperature and IR temperature sensors as well as computer software for archiving the data and graphically displaying climate records.
Expandable with numerous sensors for humidity and temperature measurement:
In addition to the integrated capacitive sensor for non-destructive moisture measurement, a large number of sensors can be connected:
- Humidity and temperature sensor
- Humidity and temperature sensors
- Precision humidity & temperature probe
- IR temperature sensor: for measuring the surface temperature of various materials
- Hand electrode: a conductance sensor for measuring gypsum, plaster, lime plaster, lime-cement plaster, cork, cellulose insulation, fill and many other materials. Likewise, the moisture or wood moisture can be measured precisely. Possible applications are, for example, construction timber, split logs, chipboard or OSB panels.
- Plug-in pair of electrodes for determining the water content of hard, set building materials
- Ram electrode: Measurement to depths of 60mm.
- Flat electrodes: measure the moisture of the fill under the screed
FAQ:
What are the advantages of the KRL method?
Regardless of whether cement screed or calcium sulphate screed or anhydrite screed - with the KRL method or in other words by referring to the equilibrium moisture content between air and screed, the residual moisture in the screed can be measured most precisely and continuously. This saves time and costs.
How does capacitive humidity measurement work?
Capacitive humidity measurement is based on measuring the electrical capacity between two electrodes. When a material becomes wet, its capacitance changes because moisture has a higher dielectric constant than the material itself.
What is the advantage of capacitive measurement compared to CM measurement?
The moisture measurement is non-destructive, since no holes are necessary in the screed and underfloor heating is not endangered. Therefore, capacitive measurement is faster and cheaper. In addition, no chemicals such as calcium carbide are used.
How quickly can I get my result?
With the CM measurement, material must first be knocked out of the screed and it takes about 20 minutes for a measured value to be available.
With capacitive humidity measurement, the measuring device is positioned at the point to be measured Screed pressed and the measured value is displayed immediately.
With the KRL method, an adjustment period of approx. 5 minutes must be waited for in order to carry out a correct measurement.
