Overview
Adhesion Tester is an intelligent adhesion testing instrument that performs hydraulic pull-off testing on coatings of a specific area. The whole process of pull-off is automatically completed, and the speed is stable and controllable to avoid human errors. The pull-off force is accurately displayed through the digital display, and MPa, psi and KN units can be selected. The upper limit of pressurization and holding time can be set to evaluate the durability of the sample.
Features
1. Portable design, built-in rechargeable lithium battery, no external power supply required, suitable for construction, production site and laboratory use;
2. U-disk storage technology, equipped with Type-c interface, connects to a computer to directly copy data without installing a driver;
3. Built-in real-time clock, saving data with experimental date and time for easy management.
4. Available in 10, 14, 20 and 50mm pull-off kit sizes with expanded functionality and resolution;
5. Before leaving the factory, it is calibrated by CMA traceable pressure sensor, and the accuracy is +/- 1% of full scale;
6. Internal storage of pull-off data, including maximum pull-off force, pull-out rate, test time and kit size;
7. Press the button to select the pull-off unit size, Measurement unit or storage reading;
8. Automatically calculate the pull-off force according to the kit size, without the need to convert the table.
9. Use cheap and high-quality aluminum kits that meet international standards;
10. Aluminum automatic middle pull-off unit to ensure uniform pull-off force and prevent unilateral pull-off.
11. Liquid crystal display, with MPa, psi, and KN units.
12. With drawing force Linear dispersion display function, observe the change of drawing force;
13. Data can be stored to 200,000;
14. The Bluetooth printer can print directly on site (optional);
15. Full Touchscreen design, one-click switch between Chinese and English, easy to operate.
Principle
The instrument is hydraulically tested on a specific area of coating, and the pulling process is completed automatically, the speed is stable and controllable, and human errors are avoided. The pulling force is accurately displayed through the digital display, and the upper limit of pressurization and the holding time can be set to evaluate the durability of the sample under pressure.
Standards
ISO 4624 "Paints and varnishes-Pull-offtest for adhesion", ASTM D4541 "StandardTest Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers", ASTM D7234 "Standard Test Method for Pull-OffAdhesion Strength of Coatings on Concrete Using Portable Pull-OffAdhesion Testers", GB/T 5210-2006 "Paints and varnish adhesion test", TB-T2965-2011 "Railway concrete bridge deck waterproof layer technical conditions" ISO 4624/16276-1
Steps
1. Select the size of the pull-off unit;
2. Set the upper limit of pressurization and the holding time.
3. Press the button to start the automatic pull-off test;
4. Observe the drawing force Linear dispersion and digital display;
5. Store or print test data.
Notice
Make sure the instrument has sufficient power before use.
• Choose the right size pull-off kit;
Avoid operating in extreme environments;
• Regularly calibrate instruments to ensure accuracy;
• Data storage attention backup;
• Bluetooth printer is optional and requires additional configuration.
