• LH-330J

(Eddy Current measurement method: For measuring
the thickness of insulating coatings on non-magnetic
metal substrates)

An eddy current is produced in the surface of a metal when
a coil through which a current of fixed frequency is brought
near the metal. This eddy current and the voltage at the
ends of the coil change in proportion to the distance be-
tween the coil and the metal surface. This change can be
determined from the current value and this is used to cal-
culate the thickness of the coating.

• LE-330J

(Electromagnetic measurement method : For measur-
ing the thickness of non-magnetic coatings on mag-
netic metal substrates)

When an alternating current electromagnet is brought near
iron (or other magnetic metal) the number of magnetic
flux lines passing through the coil changes in proportion
to the distance, thereby causing a change in the voltage
at the ends of the coil. This change in voltage is deter-
mined from the current value and this is used to compute
the thickness of the coating.

• LZ-330J(Dual Electromagnetic and Eddy Current Type)

The model LZ-330J is a dual type coating thickness tester which features both the electromagnetic and Eddy Current
measurement methods.
