Destructive Method
In early 80's PARA Electronics added another group of products to cater the Surface
Finishing Industry. Destructive & Non-Destructive Coating/Plating thickness measuring
instruments - GEDET, Delta Meter were introduced first. More additions followed
upon successful acceptance by the Indian Industry. State of Art technology lead
to introduction of microprocessor based 'Smart' Instruments like Smart GEDET, Smart
Step etc. Recently SmartStep is replaced by 'Graphic Step' and SmartGedet is replaced
by 'Graphic Gedet'

GEDET is a versatile and sophisticated instrument for measurement of coatings of
metal or alloy on substrates by electroplating or other methods. It is simple enough
to be welcomed by operator of average skill when a large number of routine measurements
on standard metallic coating are to be made. At the same time, it is sophisticated
enough to be employed by a scientist for his investigation purposes on metallic
and alloy coatings. It works on Coulometric principle. It has a very high accuracy
and repeatability. It can measure thickness on flat or curved surfaces. GEDET also
measures coating on known length of wire or pins using Acrylic cell which is supplied
as an accessory.

Smart Sidet is a smart, versatile and sophisticated instrument for measurement of coatings of metals as well as alloys applied on substrate by electroplating or other methods. It fulfills a long standing need on the Indian market for a smart, reliable and accurate coating thickness measuring instrument.
Smart Sidet has facility to store and transfer the results to PC via USB. It also provides various built-in plate / base combinations.
|
|
|
|
Smart Sidet works on Coulometric principle. Smart Sidet is a microcontroller based system hence it is more flexible in design. Menu driven software enables user to select the desired plate / base combination. Once this is selected through Menu, Smart Sidet carries out thickness measurement without manual intervention. It has high accuracy & repeatability. It can measure thickness on thick and flat surfaces as well as plating on wire.
Smart Sidet can be supplied either 3.5 mm dia or 2.5 mm dia or 1.5 mm dia gaskets. User can decide about the gasket diameter depending upon the available flat surface on the plated sample and inform us about his choice of gasket at the time of ordering.

Graphic Step is an advanced version of our earlier Smart Step. It works on
Coulometric Principle. It measures plating thickness of various metallic coatings
on variety of base materials. Step measurement of Duplex and Triplex Nickel is also
possible in this instrument. In Duplex Nickel on Steel / Copper combination, it
measures thickness of bright and semi-bright nickel and measures electrochemical
potential between these two layers. In Triplex Nickel on Steel / Copper combination,
instrument measures the thickness of bright nickel, active layer and semi-bright
nickel and measures electrochemical potential between two layers. Graphic Gedet
is similar to Graphic Step except can not perform Step Measurement
|
|
|
Graphic Gedet Mode: Thickness Measurement
More than 20 plate/base combinations can be tested on Graphic Step. Combinations
are listed on next page. Instrument is very easy to operate. It has a setup mode
to select the plate—base combination. Using UP/Down/Scroll keys, required plate-base
combination can be selected. After selection, instrument goes into measurement mode.
Air agitation is necessary to maintain proper electrochemical contact and to maintain
constant rate of de-plating. After setting up the sample, just press the Start key.
Measurement will start.
No further adjustment of any kind is necessary. Constant current passes through
the cell and etching takes place. Instrument stops automatically whenever base material
is reached. During measurement cycle, instrument displays the thickness in microns
as well as mils. Also displays the cell voltage. Operator can selectively store
the reading which can be used for generating statistical information. Statistics
like MIN, MAX, AVG and Standard Deviation will be done automatically and displayed
on LCD screen.

Graphic Step : Duplex / Triplex Step Measurement
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.
|
|
Precautions :
Silver/Silver Chloride Electrode and the Gasket are the key components in step measurement.
Periodic reconditioning of electrode is necessary for accurate measurement. Instrument
has a facility to recondition the electrode. Care should taken while handing the
rubber gasket. SS cell should be cleaned after every measurement. Conditioning of
Silver/Silver Chloride Electrode, cleaning of cell and gasket and proper setup of
sample will lead to successful step measurement.
|
|
Software :
|
|
Graphic Step stores data in a non-volatile memory. Even after switching off the
instrument, the data array is preserved. Data can be transferred to PC via USB port.
Data retrieval software will be supplied for data storage and transfer. All the
calculations for determination of step(s) or layer thickness are done automatically
at the end of the measurement. Instrument determines the points (thresholds) at
which change in layer takes place. Due to non-uniform coating, sometimes the instrument
may show wrong results. In such cases, transfer the data to PC and run the software.
In the software, user can change the thresholds by looking at the graph displayed
on screen. This helps to get the proper and more accurate results.
