Graphic Step: Duplex / Triplex Step Measurement

We have established a distinct position in the market by affianced in manufacturing and supplying a quality proven array of Graphic Step: Duplex / Triplex Step Measurement for our important clients in Mumbai, Maharashtra, India. Instrument goes into Step measurement mode whenever the user selects Duplex / Triplex Nickel plate - base combination. In Step measurement, setup the sample. Use reference electrode and SN-15 electrolytic solution for measurement of electrochemical potential between two layers. Press Start key to start measurement. Instrument shows graph of electrochemical potential versus thickness on LCD screen. Typical graph for Duplex Nickel is shown in the picture. Instrument passes constant current through cell and etching starts. First the bright Nickel layer gets removed. Then etching of the semi-bright nickel layer starts. Cell voltage rises at this time. Rise in cell voltage can be observed on LCD screen. After etching of semi-bright layer, base material is exposed to the solution. At this point, cell voltage rises for copper or drops for steel base material. Instrument detects this change and stops automatically. Step change in voltage is calculated automatically. Also the thickness of bright and semi-bright nickel layer is calculated and displayed on screen. For Triplex nickel layer, instrument measures the thickness of bright nickel, active layer and semi-bright nickel and measures electrochemical potential between two layers.
