TAIJIN / ELECTROLYTIC COATING THICKNESS GAUGES
NEW VERSION · 8-INCH TOUCH SCREEN
ET-3CNew-Version Touch Screen Electrolytic Coating Thickness Gauge
An 8-inch touch-screen coulometric gauge for single-layer and multilayer coating measurement, including nickel-layer thickness and potential-difference analysis.
The ET-3C uses the anodic dissolution (coulometric) method to determine the thickness of metallic coatings. Its 8-inch resistive touch screen supports one-touch testing, thickness and curve review, multilayer measurement sequences and on-instrument nickel potential-difference analysis. PC software connectivity and integrated thermal printing provide additional analysis and reporting options.
