TJH200 Portable Hardness Tester

Features: LCD display of 128×64 matrix is used. Using the D high precision impact device Converts to all common hardness scales(HV ,HB,HRC,HRB,HRA,HS). English displaying and menu operating, the operation is easy and           convenient. Hermetically sealed metal shell, solid and durable, has excellent resistance to vibration, shock and electromagnetic interference ability. With USB2.0 interface, multiple communication modes are adopted to            meet customized requirements of various users. Equipped with a data processing software, through the USB interface, can exchange data with computer printing and parameter setting Equipped with 7 types of impact devices which need not to be           recalibrated when changing them, the system can identify the type of            impact device automatically. Max 600 groups（impact times:32～1）of data can be stored at internal            non volatile data storage. Upper and lower limit of hardness can be preset; When the tested value          exceeds the limits, alarm will send out automatically to make convenient          for the requirements of batch measurements.          Back light display has been used to make convenient for the use in poor          light. Test values software calibration function. Material of “cast steel” is added; HB values can be read out directly           when D/DC impact device is used to measure “cast steel” work piece. Printer be separated from main unit and copies of testing results can be           printed as required. Power is two of AA battery. Continuous working period: approx. 200 h           (no back light on). Software of PC can be installed according to the requirements of user,           the function will be more powerful to satisfy the more strict demands of           quality control and management. Failure analysis of pressure vessel, steam turbo-generator set and other           equipment Narrow testing space where work piece installed Technical Specifications: Measuring  Range HLD(170-960) (170-960)HLD，(19-651)HB，(13-100)HRB，(17-68.5)HRC，(59-85)HRA，(80-976)HV、（30~110）HS Impact  Directions Up, down, horizontal, slanting up, slanting down Tensile Strenght 374 to 2652 N/m 2 Measuring  Materials Steel and cast steel, alloy tool steel, stainless steel, gray cast iron, nodular cast iron, cast aluminum alloy, copper zinc alloys (brass), an alloy of copper and tin, copper (bronze), forged steel Hardness  Scales HL, HB, HRB, HRC, HRA, HV,HS.
