Tramex CMEX II Digital Concrete Moisture Encounter

Tramex's CMEXpert II Concrete Moisture Encounter provides instant non-destructive measurement of moisture content in concrete and othe floors and screed. With a concrete moisture scale of up to 6.9%, CMEXII is suitable for testing new hardened slab as well as older concrete slab. Like the analogue model CME4, CMEX II operates by electrical impedence; 8 co-planar electrodes on the base of the unit transmit signals into the concrete to measure moisture non-invasively, to a depth of about 1/2" (12.5 mm).

Additionally, CMExpertII incorporates plug-in ports to use Tramex's Hygro-I® relative humidity probe for in-situ and hood-type RH testing in compliance with ASTM F2170* for the flooring industry, as well as their pin-type wood moisture probe, making the CMEII an ideal instrument for use in the flooring industry, flood and water damage, restoration, and indoor air quality industries. Hygro-I probes are available individually, and in packs of 2, 6, 12, 25, 50, and 100 probes.
