Model: 435 Name: 435 hardness tester Price: 0 Brand: Germany ERICHSEN Category: Physical properties of 435 hardness tester instrumentation design: pressure range between 0-20N. Equipment placed on the test surface. So that it can against the hardness of quality suppliers, marking wheel lock in a position where the two guide wheels to preset spring pressure on the surface pressure, spring strength range can be divided into three parts, each containing a Root replaceable spring. Range 1:0-3 N Sensitivity: 0.1 N Scale 2:0-10 N Sensitivity: 0.5 N Scale 3:0-20 N Sensitivity: 1.0 N Germany 435 hardness tester operation method: Scratch tool is circular, with lock tight means, made of a special plastic or metal. Mounted on the screw, get pressure from a coil spring, spring provides an adjustable first round choice test based on the test requirements, such as scratch-resistant plastic wheels for Leeb hardness testing professional agent, copper wheel or other special wheels for metal scratches. After tightening the screws, mark the wheel does not rotate, and then set the appropriate pressure springs provide a needed. The instrument is then pressed down on the test surface, the guide wheel contact with the surface. The instrument is moved a distance (a few centimeters), the rolling surface of the wheel, to produce a scratch hardness of the rapidly moving process, the test result is a spring force in Newtons. This force must be generated hardness industry-leading marks in a visible, but not cracks or scratches. If the purpose of the so-called metal marker effects, the results will be expressed as the surface of a black or gray print timing spring force. Note: Mark wheel will wear after use, after performing the test 100, their position must be changed. To move forward along the periphery of 2mm, previously used tags round the point should be added to a scratch mark.
