How to perform a test with the Concrete Moisture Encounter (CME5, CMEX5, CME4, CMEX2)

May 17th 2021

Remove any dust or foreign matter from the Concrete Moisture Meter electrodes before commencing tests. Make sure that the floor slab being tested is clean and bare and free from dust, dirt or standing water.
Push the ON button and press the instrument directly onto the surface of the material being tested ensuring that all of the electrode spring loaded pins are fully compressed. Read the moisture measurement from the appropriate scale of the display.
On a rough surface, take a number of readings in close proximity to one another such as 3 to 5 readings within an area of 1 ft2 (929cm2) at each location. If the readings vary, always use the one with the highest value.
Perform at least eight tests for the first 1000ft2 (100m2) and at least five additional tests for each additional 1000ft2 (100m2). Include test locations in the centre of the floor and within 3ft (1m) of each exterior wall.
