The TC-20M Manual Adhesion Tester is an intelligent adhesion testing instrument newly developed by our company with reference to similar foreign products. It performs pull-off tests on coatings of specific areas through hydraulic pressure. The pull-off force is accurately displayed via a digital display and offers two different unit options: MPa and psi. This instrument features simple operation, precise data, low maintenance costs, and affordable consumables. It is widely used for adhesion testing of coatings on concrete substrates, anti-corrosion coatings, or between different layers in multi-coat systems.

Product Features:
■ Equipped with a standard Micro-USB interface. When connected to a computer, the instrument functions like a USB drive, allowing direct copying of stored experimental data without the need for any software installation, making it simple and convenient to use;

■ Complies with GB/T 5210, ASTM D4541/D7234, ISO 4624/16276-1, and other standards;

■ Built-in real-time clock ensures all saved data includes corresponding test dates and times, facilitating user management and summarization of experimental data;

■ Offers pull-off spindle sizes of 10, 14, 20, and 50mm for products with varying bonding strengths, expanding the instrument’s functionality and resolution;

■ Internally stores pull-off data, including maximum pull-off force, pull-off rate, test time, and spindle size. The pull-off rate display allows operators to easily observe and adjust the pull-off rate, complying with international standard testing methods;

■ Simply press a button to select the pull-off unit size, change the measurement unit, or store readings.
