Overview
CTM-208STEP Electrolytic Thickness Gauge is a professional instrument launched by COATTEST INSTRUMENT for accurate measurement of platings thickness and multi-layer nickel potential difference. It is suitable for a variety of metal platings, composite platings and alloy platings, supports single-layer and composite multi-layer measurement, and has data processing and report generation functions.
Features
1. Wide range of measurement plating: can measure Cr, Ni, Cu, Zn, Sn, Ag, Au, Cd, Co, In, Pb and other single metal platings, as well as composite platings (such as Cr/Ni/Cu) and alloy platings (such as NiP, ZnNi) about 20 combinations.
2. Strong substrate compatibility: support metal, Non-metallic, NdFeB and other substrates, basically unrestricted.
3. The test size is optional: standard φ 2.4mm, φ 1.7mm test head, optional φ 1.2, φ 1.0, φ 0.8mm.
4. Flexible data processing: Connectivity can display thickness and potential changes in real time Linear dispersion, the results can be saved and printed; stand-alone can display values and print statistical reports.
5. Excellent measurement performance: Measurement range 0~ 300μm, Indication Error ≤ +/- 10%, reproducibility ≤ 5%, thickness resolution 0.01μm, potential accuracy 0.01mv.
Principle
The instrument uses the principle of electrolysis method (Coulometry) for measurement. Through electrolysis liquid and specific current, the platings to be measured are used as anodes for electrolysis dissolving. The thickness of platings is accurately calculated according to the Basis Weight relationship between the amount of electricity consumed in the electrolysis process (Coulometry) and the thickness of platings. At the same time, in the multi-layer nickel measurement process, by monitoring the change of potential, the thickness of different nickel layers and their potential difference can be distinguished and measured.
Applications
Automobile Motorcycle Industry, Aerospace and Marine Industry, Bicycle Industry, Electronics Industry, Daily Hardware Industry, Sanitary Ware Industry, Plastic Eletroplating Industry, Neodymium-Iron-Boron Industry, Standard Parts Industry, Technical Supervision Department, Scientific Research Institutions
Steps
1. Preparation: Select the appropriate electrolysis solution and test head size according to the platings and matrix to be tested, and install it.
2. Sample preparation: Clean the surface of the sample to be tested to ensure that the test area is smooth and free of oil stains.
3. Instrument settings: Connect the instrument to the computer (if Connectivity is required), select or set the corresponding platings/matrix combination parameters in the software.
4. Start the test: Press the test head vertically and tightly on the sample to be tested area to start the test procedure. The instrument will automatically perform electrolysis and record data.
5. Data reading and analysis: During the test, the thickness and potential changes are observed in real time. Linear dispersion (Connectivity) or numerical value (stand-alone). After the test, the instrument automatically calculates and displays the platings thickness results.
6. Result processing: Save the test data and print a single test report or a statistical report of multiple data as needed.
Notice
* Measurement range is preferably 0.03~ 75μm, the error will gradually increase when exceeding 75μm, please pay attention when using.
* Be sure to select the matching electrolysis solution according to different platings and matrix materials before testing, otherwise it may affect the measurement accuracy or damage the sample.
Make sure that the test head is in good contact with the sample surface, sealing, and preventing electrolysis leakage, which will affect the test results and instruments.
* For nonconductive substrates (e.g. plastic Eletroplating), ensure that the test area is well conductive.
When the instrument is used alone, the test results cannot be stored. Please record or print the required data in time.
Regularly calibrate and maintain instruments to ensure Measurement accuracy and Stability.
