WH91 Digital LCD Coating Thickness Gauge With External Probe Ferrous Type WH91

Coating Thickness Gauge WH91 (Split Fe Type)

______________________________________________________________________

1.Application

 Fe Type (WH91): Measure non-magnetic coating thickness(Such as enamel, rubber, paint etc.)on the magnetic base(such as steel , iron , nickel, cobalt , alloy and hard magnetic steel etc.)

Special Application (WH91): Split Type can test corner and Groove etc.

Paint                                                                   Plastic film 

Powder coating                                                             Paper 

2.Introduction

This device is a portable meter. It is capable of measuring coating thickness quickly, precisely and without injury, both for the laboratory and engineering environment.

Principle of Magnetic Method (F-type probe)

When the probe contacts the cover layer, the probe and magnetic substrate forms a closed magnetic circuit; Due to the presence of non-magnetic coating, magnetic resistance changes. The thickness of the cover layer can be derived by measuring the change.

3.Features

——Thickness measurement using both Magnetic Method to measure the non-magnetic coating on a magnetic metal substrate .

——Single-point or two-point method could be used to correct probe system deviation, in order to ensure the accuracy of the device in the process of measuring.

——Automatic identify ferrous and non-ferrous substrate quickly.

——Power voltage indicator.

——Speaker beep while operating.

——Power-off automatically when idle; manually power-off available.

——Negative display function to ensure the accuracy of zero point calibration.
