• 【Newton Hardness Pen】The Newton Hardness Pen comes standard with three interchangeable tips: 0.5mm, 0.75mm, and 1mm. These varied tip sizes accommodate diverse testing requirements, enabling precise hardness measurements across materials while automatically recording data for reliable subsequent analysis. Suitable for both flat and curved surfaces, it operates without size restrictions.
• 【Hardness Measurement】During hardness testing, the device draws vertical lines of 10-20mm on the sample surface at a speed of 10mm/s. This standardized testing process quickly determines whether the sample's surface hardness falls within the measurement range of the current Newton scale on the hardness tester.
• 【Accuracy Test Range】After inputting different accuracy test ranges, the hardness tester displays precision scales (Newton force values). Different color zones correspond to distinct accuracy intervals: Blue Marker: 0-3N Red Marker: 0-10N Yellow Marker: 0-20N
• 【Hardness Tester Operation】Once the device enters the user-set accuracy range, first position the probe precisely at the center of the tester cap. Then, rotate the cap clockwise onto the main body until they form a seamless, integrated unit. The device is now ready for testing.
• 【Application Scenarios】Hardness testing provides engineers, plumbers, surveyors, and other professionals with inspection instruments that meet production efficiency requirements.
