Overview
RJ-M type pull-out Adhesion Tester is a portable instrument for measurement of metal, concrete and Miscellaneous material coating adhesion. Its self-positioning characteristics bring changes to the adhesion measurement method. The hydraulic system makes the coating of a certain diameter on the surface of the tested substrate detach to measure adhesion. The multi-function digital display shows the measurement results in MPa or KN units. The product is designed and manufactured according to international and national relevant standards. The technology is advanced and the performance is stable.
Features
1. Portable handheld instruments can be used anywhere, without the need for an external power supply. They can be used in both laboratories and on-site
2. Large and easy-to-read LCD digital display
3. Press the button to select the spindle size, Measurement unit and storage data, and automatically calculate the result according to the spindle size
4. Portable instrument case with alloy and stainless steel body, rainproof, dustproof and impact-proof
5, high quality hydraulic pump can be applied to any occasion, quality assurance for three years
6, Pressure and display system are standard Force Gauge calibrated, accuracy control within +/- 1% (full scale)
7. Self-positioning spindle has no effect on measurement results on smooth and rough surfaces
8. High-grade industrial pressure sensors ensure High Accuracy
9. Optional 10mm, 14mm, 20mm and 50mm spindles
10. LCD liquid crystal display, MPa or KN unit can be selected by pressing the button
Principle
The working principle of this instrument is to use the hydraulic system to make the coating of a certain diameter on the surface of the tested substrate to measure the adhesion of the coating.
Applications
Metal coating adhesion test, concrete coating adhesion test, Miscellaneous material coating adhesion test
Standards
ISO 4624、ASTM D 4541、ASTM D7234、GB/T 5210-2006
Steps
1. Choose the right size spindle
2. Press the button to select the spindle size and Measurement unit
3. Place the instrument on the surface of the coating to be tested
4, start the hydraulic system to remove the coating
5. Read the adhesion value on the display screen
6. Store test data as required
Notice
• Make sure the instrument is fully charged before use
• Select the spindle size that matches the test requirements
• When using on smooth and rough surfaces, ensure that the self-positioning spindle is placed correctly
• Avoid severe impact on the instrument
• Periodically calibrated for Measurement accuracy
• Hydraulic pump quality assurance for three years, pay attention to normal use and maintenance
