Guangzhou _ Leeb hardness durometer factory direct wholesale _ Leeb hardness Nanchang Xing Feng Instrument Co., Ltd. (http://www.xingfengyiqi.com) 2013 upgrade been newly introduced Model: HLJ-3200 Product Name: HLJ -3200 Leeb hardness tester Price: 0 Brand: Domestic Product categories: physical properties testing equipment HLJ-3200 Leeb hardness tester, direct measurements show that the HRC, HB, HRB, HV, HS, HL σb, widely used in machinery, metallurgy, automobile, petrochemical, aerospace pressure vessels and power industries metal hardness field testing HLJ-3200 Leeb hardness tester, direct measurements show that the HRC, HB, HRB, HV, HS, HL σb Leeb hardness using methods Widely used in machinery, metallurgy, automobile, petrochemical, aerospace pressure vessels and power industries metal hardness testing site HLJ-3200 Leeb hardness tester Details Model: 318 Name: 318 hardness test rod Price: 0 Brand: Germany ERICHSEN Category: German 318 physical properties testing equipment to test the hardness test stick principle: You can set the slider or known estimate by spring pressure. The instrument is placed vertically on the test surface to 10 mm / sec speeds draw a straight line 5 ~ 10 mm of. Test head just visible to the naked eye will produce a scratch. If the spring pressure is too high, the scratches will be very clear, if the spring pressure is too low, there will be no scratches appear. Hardness provider Newtons pressure can be controlled by locking slider required in each. This instrument is designed to measure the hardness of the protective coating. Paint, plastic coating hardness can be accurately measured by 318 hardness test stick and record the measurement surface may be flat or curved Leeb hardness brand, and regardless of size. Engraved on the pen scale includes three pressure ranges: 0-3 N (blue mark) 0-10 N (red mark) 0-20 N (yellow marker) and pressure range corresponding to the root of each spring and scale with the corresponding color code. Maintenance and repair of a clean instrument can produce a clean test results. To clean, loosen the nut hardness, remove the tick pen. Use a soft cloth to clean the rods and holes. In addition the instrument without further maintenance. Despite the solid structure hardness test rod 318, but can not stand the test head great momentum. Packing boxes with the instrument provides such a protection. When not in use, the slider should be set at zero in order to protect the accuracy of the spring. Technical data compression spring: spring steel test head: WC test head diameter: 0.5 mm (Opel) 0.75 mm (Bosch) 1.0 mm (in line with ISO 1518 and DEF) Length: 160 mm Diameter: 16 mm Weight, Weight: about 250 g
