The tester is mainly used to measure the surface flatness of furniture components, including panels, visible surfaces, doors, tabletops, and drawer fronts. It is an essential quality inspection instrument for evaluating the manufacturing accuracy and surface quality of wooden furniture, metal furniture, and bathroom furniture.

Furniture Surface Flatness Tester

Model:TD3324-P

I. Product Introduction

The Furniture Surface Flatness Tester is designed according to GB/T 3324-2017, GB/T 3325-2017, and GB 24977-2010. The tester can also be used as a reference instrument for furniture quality inspection related to ISO, EN, and ANSI/BIFMA furniture testing requirements.

With high measurement accuracy, stable structure, and easy operation, the Furniture Surface Flatness Tester is widely used in furniture manufacturers, quality inspection laboratories, research institutions, and third-party testing organizations.

II. Main Features

1. Stable Three-Leg Measuring Structure

The tester adopts a three-point support structure, which provides excellent stability during measurement and prevents shaking that may cause measurement errors.

2. High-Precision Digital Gauge

Equipped with a high-quality digital measuring gauge, the instrument provides clear readings, easy zero adjustment, and reliable measurement performance. The digital display improves testing efficiency and reduces operator errors.

3. Durable Stainless Steel Frame

The main frame is made of stainless steel, offering excellent corrosion resistance, structural stability, and long-term durability. It maintains accuracy even after extended use.

4. Portable and Easy Operation

The compact design allows convenient transportation and operation. It is suitable for laboratory testing, production line inspection, and quality control applications.

IV. Flatness Evaluation Criteria

According to relevant furniture testing standards, the allowable flatness deviation values are as follows:

V. Test Method

A flatness measuring instrument with an accuracy of not less than 0.01 mm shall be used. Select the three panels with the most severe surface unevenness and measure the distance between the tested surface and the reference straight line within a length range of 0 mm to 150 mm. The maximum measured distance is taken as the flatness deviation value.

VI. Working Principle

The Furniture Surface Flatness Tester measures the height difference between the reference support surface and the tested furniture surface.

During testing, the instrument is placed on the furniture surface, and the digital gauge measures the deviation caused by surface unevenness. The displayed value represents the flatness deviation of the tested area.

The three-point support design ensures stable positioning, while the high-precision digital indicator provides accurate and repeatable measurement results.
