Newton Hardness Test Pen, Surfaces Scratch Test Pen, with 3 Ranges - Blue Mark 0-3N/red Mark 0-10N/yellow Mark 0-20N, 3 Probes To Choose From, for Coatings Plastics Wood Metal Materials ( 0.5mm)

Uniform hardness and good coating quality are conducive to smooth production. This instrument is specially used to measure the hardness of protective coatings. Specifications: Material: Stainless steel Test range: Blue markings 0-3N, red markings 0-10N, yellow markings 0-20N Test probes: 0.75mm, 0.5mm, 1.0mm Packaging: Plastic box Product List: 1*Hardness Test Pen

• 【Newton Hardness Tester Pen】Available with three optional pen tips (0.5mm, 0.75mm, and 1mm), it accurately measures and records various hardness levels. It can be used on flat or curved surfaces, regardless of size.
• 【Hardness Measurement】Draw a 10-20mm vertical line on the sample at a speed of 10mm/s. This method determines if the surfaces hardness is less than the Newton scale of the current hardness tester.
• 【Accuracy Test Range】After entering different accuracy test ranges, the hardness tester will display an accuracy scale (force value in Newtons). Different color ranges correspond to different accuracy ranges. Blue mark: 0-3N, red mark: 0-10N, yellow mark: 0-20N.
• 【Hardness Tester】After entering different accuracy ranges, place the probe in the middle of the cap end of the tester. The cap screws onto the tester to form an integral unit.
• 【Applications】Hardness testing provides engineers, plumbers, surveyors, and other personnel with a testing instrument that meets the requirements for smooth production opera
