Pull-Off Adhesion Tester | Automatic Digital Coating Bond Strength Meter – BGD500S

Product Description:

The BGD500S Automatic Digital Pull-Off Adhesion Tester is a precision tool designed to quantitatively measure the bond strength between coatings and substrates. Unlike traditional cross-hatch or tape tests, this device uses a fully automatic hydraulic pull-off method, providing accurate and repeatable results.

With selectable measurement units (MPa or psi), adjustable pressurization limits, and dwell time settings, the BGD500S ensures controlled testing conditions for reliable evaluations. It supports multiple dolly sizes, making it suitable for a wide range of coating systems and substrates—from concrete to metal and multi-layer protection systems.

Built to meet GB/T 5210, ASTM D4541/D7234, and ISO 4624/16276-1, the BGD500S is ideal for coating developers, QC labs, and field inspectors who need consistent, standards-compliant adhesion data. Lightweight and battery-powered, it offers portability and low operating costs, with minimal maintenance.
