Concrete Encounter CME4

for measuring moisture content … instantly… in concrete floors and floor screeds without the need to drill or damage the surface.   SCREEDS AND CONCRETE FLOORS MUST BE DRY BEFORE THE FLOOR COVERING IS INSTALLED

Regular checking of moisture content during the drying out period of a new concrete floor or floor screed is important to ensure it has reached sufficient dryness to accept the floor covering.
Excess moisture in the concrete could cause latent problems such as condensation or failure of the adhesive under the floor covering.
The Concrete Encounter 4 will give you an instant reading of moisture content up to 6% concrete; up to 0 – 10 comparative on gypsum screed enabling you to make an informed decisions on when to install the floor covering.
To use, simply switch on and hold the instrument firmly against the surface. As many non-destructive tests as you need can be carried out in seconds without the need to drill or damage the concrete.

If you are interested in the Flooring Inspection Kit, please note that it includes both the Concrete Moisture Encounter 4 and the Professional Moisture Meter.


The Skipper Plus

The SKIPPER Plus non-destructive moisture meter provides a complete, safe method for detecting excess moisture in GRP and wooden boats. Three scales of sensitivity allow moisture detection in salt or fresh water.

How it works:
The Skipper Plus moisture meter detects moisture in wood or GRP (Glass Reinforced Plastic) by measuring the resistance between two low frequency AC signals transmitted from the soft rubber electrodes on the base of the instrument.
Because salt water is more conductive than fresh water, the Skipper is fitted with different ranges of sensitivity to allow testing of wood or GRP in either fresh or salt water environments.
Simply select the correct scale:
Scale 1: Moisture content in hardwood for fresh water (%H20))
Scale 2: Moisture in GRP (Comparative)
Scale 3: Surface Moisture(Comparative)
