The Concrete Moisture Probe - a.k.a. “The Determinator”, measures the in-situ moisture content within a concrete floor or slab.


This Concrete Moisture Probe is used with a concrete moisture meter from the Tramex Concrete Moisture Encounter range, the CME5, CMEX5 as well as previous versions of Tramex Concrete Moisture Meters, the CME4 and CMEX2. 

The Concrete Moisture Probe provides in-situ Moisture Content readings in a Tramex Unified Concrete Moisture Test Method - quantitative Moisture Content measurements are taken in both the top ¾ inch layer and within the body of concrete floors and slabs down to an extendable depth of up to 4" (100mm) and a Diameter 3/4” (19mm).

The Determinator helps determine if moisture within the concrete slab is originating from below, within or above the slab. This information can be essential in establishing the next step in fixing moisture problems in a concrete slab.

The Concrete Moisture Probe can only be used with a Tramex Concrete Moisture Meters. It does not work alone. The Determinator is supplied in a Tramex hard case with allocated space for your Concrete Moisture Meter.


The Determinator is also available as part of the following kits:

  • The  Concrete Determinator Tech Kit, which includes the CMEX5 Concrete Moisture Meter for non-destructive quantitative testing of concrete and comparative testing per ASTM F2659.  
  • The Concrete Determinator Inspector Kit is the complete kit for instant and precise testing of both Surface and In-Body Concrete Moisture Content in floors and slabs using a unified gravimetric-based testing method. It includes the CMEX5 digital concrete moisture meter, the reusable Concrete Moisture Probe, a reusable plug-in Hygro-i2 ® RH probe for in-situ testing of concrete as per ASTM F2170, an infrared surface thermometer for surface temperature and dew point conditions when used in conjunction with the CMEX5 hygrometer and the CMEX5 extension handle.


Concrete Moisture Probe Features

  • Instant and Accurate
  • Designed to work in the same drill-hole made for the F2170 test.
  • Eliminate confusion between in-situ Relative Humidity tests and surface Moisture Content tests.
  • Determine if moisture is coming from below or above the concrete slab surface.
  • 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, (CME4 and CMEX2)


Concrete Moisture Probe Design

The Concrete Moisture Probe when used with Tramex Concrete Moisture Encounter 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" (19mm) 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” (10cm). This field penetrates the material under test. The very small alternating current flowing through the field is inversely proportional to the impedance of the material. The instrument detects this current, determines its amplitude and thus derives the moisture value.


Tramex Concrete Moisture Probe - Operating Procedure

The Determinator cradle should be 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.
