TRAMEX THE DETERMINATOR CMP User manual
GENERAL
The Determinator and CME5, CMEX5 (or older
Tramex Concrete Meters CME4 and CMEX2)
allow for a unified gravimetric-based testing
method of moisture content (%MC) both on the
surface and within the body of the concrete.
%MC readings for both the in-situ and the
non-destructive surface tests eliminate
confusion between different testing method
data.
The Determinator conductive probes are
reusable, extendable, and require no plastic
hole liners.
The hole diameter required (¾”, 19mm) is the
same for the Hygro-i2 RH test as per F2170.
The Concrete Moisture Probe consists of a
cradle, a probe tip and two extension segments.
Choose to use the extension segment(s), or not,
depending on the depth of the slab. The probe
should be inserted to approximately 40% of
the depth of the slab.

ASSEMBLY
1¼” 2” 1”
Probe Testing:
Determine the approximate depth of the
concrete slab.
Connect extension segment(s) to appropriate
depth:
Concrete between 2" to 4" in depth shall
require approximately 1 1/4" of probe depth.
Concrete between 4” to 6” in depth shall
require approximately 2 1/4” of probe depth.
Concrete between 6” to 9” in depth shall
require approximately 3 1/4” of probe depth.
Concrete between 9" to 11" in depth shall
require approximately 4 1/4" of probe depth.
* The probe should be inserted to approxi-
mately 40% of the depth of the slab.
* Similar to ASTM F2170 Recommendations
for frequency of use: 3 Tests per 1,000
sq.ft. and 1 additional test for every addi-
tional 1,000 sq.ft. or partition thereof.
Insert the Concrete Moisture Probe into the
hole so that the cradle is flat on the surface.

OPERATION
•
•
•
Place yourTramex Concrete meter into the
cradle of the CMP and ensure that all of the
electrode spring-loaded pins are fully
compressed, both on the CMP and the CME.
Take 4 readings by turning the Concrete
Moisture Probe and CME meter from ‘12
o’clock’ to 3, 6 and 9 o’clock positions. Record
the highest reading, discarding any obvious
anomalies.
Record the readings using the Tramex Meters
App (when using the CME5 or CMEX5).
