Characteristics of Electrical resistance type thickness tester RST-231

High precision measurement is possible in a short time(0.7 seconds)

measure meal film on insulator(Copper foil of printed board・plating etc.) in a short time It is not layer of double sided board or multilayer board

Easy-to-see screen configuration

Easy to see the screen bigger, brighter with personal computer specification

Easy calibration and measurement

Easy calibration and measurementTwo measurement ranges can be selected, 2 to 200 micron of metal coating can be measured2

Various figures can be seen immediately

After statistical processing, histograms, profiles and x-R charts can be viewed immediately.

Abnormal value detection function

If the upper and lower limits of the film thickness are set, an abnormal value is notified.

We cope with exchange every one probe

If the probe tip is damaged, it can be replaced for each tip and repair can be done at low cost.

Easy statistical processing

Measurement data can be stored for each channel,you can set statistical items later on the measurement data and perform statistical processing.

Up to 40 channels can be registered

Up to 40 channels can be registered and By user name or part number etc. Register separately,you can manage channels.

We cope with exchange every one probe

4 probe (Kelvin type) is adopted,Double-sided and multi-layered substrates can be measured with high accuracy without being affected by the back surface or internal layers.

Measurement principle

Measurement principle   The probe has four metal pins (probes) standing on a straight line.
Contact the metal foil or metal plating surface on the insulator to measure these four probes.Apply a constant current (I) to the two outer probes,Measure the voltage (V).Under certain conditions, the thickness (T) of the metal foil or metal plating in contact with the probe can be calculated by the following equation.
T = K × I ÷ V
Here, K is a constant
Therefore, the thickness of metal foil and metal plating can be measured by measuring the voltage between the two inner probes.
