Product Type: JZME-4100 Product Name: HLJ-4100 hardness tester pen Price: 0 Brand: Domestic Product Category: Physics Detector Product Description: Features a full measure (self-knowledge test direction), measure the vertical direction Jia. 2 can be based on the capacity of the SD card mass storage. Three original measurement is more narrow space eccentric design. 4 first release button pits more humane. 5 first loaded knurled sleeve appearance generally. 6 pioneered mass storage data storage SD timely delivery can be achieved. 7 for your safety and environmental considerations The machine adopts the 7th battery is more suitable for field work eight auto-correction feature nine adjustable built-in clock display year, month, day, hour, minute ﹑ seconds. Model: 435 Product Name: 435 hardness tester Price: 0 Brand: Germany ERICHSEN Category: Physics 435 hardness tester instrumentation design: 0-20N range between pressure. Instruments placed on the test surface. So that it can against the two guide wheels on the wheel lock in a location marker Leeb hardness prices to a preset pressure in the spring pressure on the surface of the spring strength range can be divided into three sections, each containing one to replacement springs. 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: scratches tools is circular, lockable gripping means, by a special plastic or metal. Mounted on the screws, obtained from a coil spring pressure in the hardness special offers, provide an adjustable spring first select the test wheel according to test requirements, such as plastic wheels for scratch resistance test, copper wheel or other special wheel for metal scratches. After tightening the screws, marking wheels can not rotate, and then set the spring to provide a suitable pressure required. Then test the instrument on press down on the surface, so that the guide wheel contact with the surface. Instrument moves some distance (about a few centimeters) high precision in the hardness, the wheel rolling on the surface, in the process of moving quickly produce a scratch test result is the spring force, the unit Newton. This force must generate a visible traces, but not cracks or scratches. If the aim 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, during a test 100, to change their position. To move forward along the periphery of 2mm, the previously used marker wheel should be added that a scratch mark point.
