LBXH-M Paint and Varnish Pull-Off Adhesion Tester

The XH‑M pull‑off adhesion tester can measure the adhesion of coatings on metal, concrete, and other substrates—its self‑positioning feature has brought a revolutionary change to adhesion measurement. The instrument operates by using a hydraulic system to detach a coated area of specified diameter from the substrate, thereby determining the coating’s adhesion. Its multifunctional digital display shows the adhesion value in either MPa or kN. ① ISO 4624 “Paints and varnishes—Pull‑off test for adhesion” ② ASTM D 4541 “Standard test method for pull‑off strength of coatings using portable adhesion testers” ③ ASTM D7234 “Standard test method for pull‑off adhesion strength of coatings on concrete using portable pull‑off adhesion testers” ④ GB/T 5210‑2006 “Paints and varnishes—Adhesion test by pull‑off method”

LBXH-M Paint and Varnish Pull-Off Adhesion Tester

Description

Product Introduction:

The XH‑M pull‑off adhesion tester can measure the adhesion of coatings on metal, concrete, and other substrates—its self‑positioning feature has ushered in a new era in adhesion measurement. The instrument operates by using a hydraulic system to detach a coated area of specified diameter from the substrate, thereby quantifying coating adhesion. Its multifunctional digital display shows the adhesion value in either MPa or kN.

① ISO 4624 “Paints and varnishes—Pull-off test for adhesion”

② ASTM D 4541 “Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers”

③ ASTM D7234 “Standard Test Method for Pull-Off Adhesion Strength of Coatings on Concrete Using Portable Pull-Off Adhesion Testers”

④ GB/T 5210-2006 “Paints and Varnishes — Pull-off Adhesion Test”

Product Features:

1. A portable, handheld instrument that can be used in any setting without an external power source—suitable for both laboratory and field applications.

2. Large, easy-to-read LCD digital display.

3. Use the buttons to select the spindle size, measurement units, and data storage; the results are calculated automatically based on the selected spindle size.

4. The portable instrument case features an alloy and stainless steel body, offering protection against rain, dust, and impacts.

5. High-quality hydraulic pumps are suitable for any application and come with a three-year warranty.

6. Both the pressure and display systems have been calibrated using a standard dynamometer, with accuracy maintained within ±1% of full scale.

7. The self‑positioning spindle has no effect on the measurement results, regardless of whether the surface is smooth or rough.

8. High‑grade industrial pressure sensors ensure sustained high accuracy.

9. Optional spindles of 10 mm, 14 mm, 20 mm, and 50 mm.

10. LCD display; allows selection of either MPa or kN units via button press.
