Biuged BGD 500/S Automatic Digital Pull‑Off Adhesion Tester

The Biuged BGD 500/S Automatic Digital Pull‑Off Adhesion Tester is an intelligent, fully automated instrument designed to measure the tensile force required to detach a coating from its substrate. Using an electronically controlled hydraulic system, it applies smooth, continuous pull‑off pressure with minimal operator influence. The digital LCD display and internal data storage make it ideal for laboratory, field, and production‑line adhesion testing. The tester evaluates pull‑off adhesion strength by bonding a metal dolly to the coated surface with a high‑strength adhesive. After curing, the instrument applies a steadily increasing tensile force perpendicular to the surface until the coating detaches or a specified limit is reached. The maximum pressure recorded represents the coating’s adhesion strength. The BGD 500/S automates the entire pull‑off process, ensuring consistent, repeatable results.

Key Features

Standards‑Aligned Automatic Operation

The BGD 500/S uses an electronically controlled hydraulic pump to apply smooth, continuous pull‑off pressure automatically. This greatly reduces operator effort and eliminates variability caused by manual pumping. The system stores maximum pressure, pull rate, test time, and dolly size for traceable reporting.

Portable, Self‑Contained Design

A compact body with a built‑in rechargeable lithium battery allows testing anywhere without external power. All tools required for testing are included.

Digital LCD Pressure Display

Pressure is displayed digitally with 0.01 MPa resolution and ±1% full‑scale accuracy, ensuring clear, precise readings.

Interchangeable Dollies for Multiple Ranges

Four dolly sizes support a wide range of coating strengths:

• 20 mm (standard)

• 10 mm, 14 mm, 50 mm (optional)

Each dolly size has its own maximum pressure range and pull‑rate settings, allowing accurate testing of both high‑strength and low‑strength coatings.

PID‑Controlled Pull Rate

A closed‑loop PID system ensures stable, adjustable pull‑off rates tailored to the dolly size, improving repeatability and compliance with test requirements.
