Concrete Moisture Encounter

This concrete moisture encounter provides an instantaneous, nondestructive moisture measurement on concrete floors. Simply brush away any dust or debris, switch on the concrete encounter, hold it against the concrete, and take the reading from the clear analog dial. The unit transmits a low-frequency signal calibrated to give average moisture content to 100 mm depth in 0-6% H20 range. A 9 V PP3 battery powers the unit.
