In the process of observing metal materials and metallographic structure, Metallographic Microscope often encounters three common problems: glare on the surface of the sample, dark field of view, and imaging color distortion, which not only affect the observation effect, but also easily lead to misjudgment of metallographic structure. The following compiles practical fault causes and original solutions based on practical experience.

Manual Rockwell Hardness Tester is a commonly used device for metal hardness testing. The hardness is determined by applying Test Force and MeasurementIndentation residual depth in two steps, as follows:

Description of the phenomenon: nThe surface of the specimen presents a multi-layer plane feeling, imaging is blurred, Profile is unclear, and ghost virtual images appear. nCause: nThe stress of the specimen during manual grinding is uneven, and the local pressure deviation causes the surface grinding flatness to be inconsistent, forming Height low staggered multi-plane structure, which eventually causes microscopic imaging virtual images.

1. Daily maintenance (after each test/daily) n n1. Clean (must do) n nWipe the rack, table, fixture, and sensor surfaces with a dry soft cloth to remove specimen debris, dust, and grease.

What is the main purpose of the Constant Temp & Humidity Test Machine? n WanveiWV-HH SeriesConstant Temp & Humidity Test Machine can simulate climatic environments such as High Temperature, Low Temperature, Humidity, Humidity Cycle, and Alternating Humidity and Heat. Testing products are resistant to temperature, humidity, aging, and environmental adaptability, and are suitable for reliability testing in industries such as Electronics, Automotive, Plastics, New Energy, and Building Materials.

The instrument should be placed in a clean, dry indoor environment. Recommended temperature: 20°C ±5°C, humidity below 60%, to avoid optical element contamination, metal part rust, or dust entering motion guide rails affecting instrument precision.
