CP-D4
Concrete Moisture Meter
INTRODUCTION
CP-D4 meter was designed in order to measure concrete
humidity. Its unquestionable advantage is nondestructive
method of measurement with simultaneous high accuracy
and easiness of use.

1. General function
CP-D4 meter calculates humidity of analyzed material by measuring its electrical impedance. The relation
between humidity of certain material and its impedance is directly proportional. Impedance is measured
through generating low frequency electric field between electrodes. The meter measures low intensity alter
-
nating current flowing through electric field and on that basis calculates moisture of tested material.
