Detection equipment can measure various product performance, and quality is crucial for such equipment. However, when users are purchasing detection equipment, they often struggle to differentiate between good and bad instruments. Below, we provide some methods to help distinguish between high-quality and subpar detection instruments, hoping they will be helpful to everyone.

Poor quality testing equipment manifests as:

1. Various labels on the testing machine are not clear. The labels are not fixed in a prominent location. The fixed position of the labels is incorrect, uneven, unstable, and crooked.

2. Surface spots on electroplated parts, uneven coating, and peeling issues are observed.

3. The testing machine's surface features protrusions, indentations, uneven textures, and other damages not specified by the patterns.

4. The surface finish of black parts is uneven, exhibiting spots, rust, and other phenomena.

5. There is a noticeable misalignment at the edge of the mating surfaces of the machine's components. It is not convenient to load or unload the doors and covers.

6. The trial paint and varnish colors are unattractive and lack elegance; the color tones are not soft, the color matching is inconsistent, the boundaries between different colors are not clear, and there is mutual contamination.

7. The埋头 screw protrudes from the outer surface of the part, with a distinct eccentricity between its head and the countersink.

The paint and putty on the testing machine lack sufficient strength, failing to resist oil and corrosion, with peeling and flaking occurring.

The processed surfaces of the test machine parts show rust, burrs, dings, scratches, and other defects.

10. All unprocessed surfaces of the test machine's parts and accessories were not primed with paint. Prior to priming, rust, sand, oil, and other contaminants were not thoroughly removed. The painted surfaces were incomplete, uneven, and not smooth, with inconsistencies in color, spots, creases, bubbles, and adhesives.
