The Tramex Concrete Moisture Probe, The Determinator, provides in-situ moisture content readings in concrete. It extends the capabilities of the Tramex Concrete Moisture Encounter range (CME5, CMEX5, and the older CME4 and CMEX2 meters), providing in-situ moisture content readings as part of the Tramex Unified Moisture Content Test Method. This method delivers quantitative moisture content measurements in both the top 3/4 inch layer and within the body of concrete floors and slabs, down to an extendable depth of up to 4 inches (100 mm) using a 3/4 inch (19 mm) diameter probe.

The Determinator is supplied in a Tramex hard case with allocated space for your Tramex Concrete Moisture meter.

The probe, when used with Tramex CME instruments, operates on the principle that the electrical impedance of a material varies with its moisture content. The CME instrument is pressed onto the CMP cradle, which is pressed onto the material surface with the pins fully compressed and the probe inserted into the pre-drilled 3/4 inch (19 mm) hole to measure the moisture content. The electrical impedance is measured by creating a low frequency alternating electric field between the electrodes and the probe, to a depth of up to 4 inches (10 cm). The instrument detects the very small alternating current flowing through the field, determines its amplitude and thus derives the moisture value.

Operating procedure: the Determinator cradle should sit flat on the slab surface and the Tramex Concrete Moisture Meter placed and firmly pressed onto the cradle with the pins fully compressed. The probe reads from the bottom, within the body of the slab, up to the surface.

Features

• Instant and accurate
• Designed to work in the same drill hole made for the ASTM F2170 test
• Eliminates confusion between in-situ relative humidity tests and surface moisture content tests
• Determines whether moisture is coming from below or above the concrete slab surface
• Helps determine the type and extent of mitigation if needed
• Reusable, extendable, and requires no plastic hole liners
• Can be used in conjunction with Tramex Concrete Moisture Encounters CME5, CMEX5 (also CME4 and CMEX2)

Applications

1. In-situ (in-body) moisture content assessment of concrete floors and slabs
2. Concrete moisture testing before flooring or coating installation
3. Concrete inspection, flooring, concrete coating, water damage restoration and concrete surveying
