RHL60 Portable Hardness Tester with Integrated Printer

RHL60 Leeb Hardness Tester with Integrated Printer OLED display of 128×64 matrix is used., highlight display; no viewing angle Converts to all common hardness scales(HV ,HB,HRC,HRB,HRA,HS). English displaying and menu operating, the operation is easy and convenient. With USB2.0 interface, multiple communication modes are adopted to meet customized requirements of various users. 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. Auto power off to save energy.. 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. Thermal printer integrated, convenient for in field printing. NI-MH rechargeable battery as the power source. Charge circuit integrated inside the instrument. Continuous working period of no less than 150 hours 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.  Main Application l  The assembled machinery and permanently installed parts l  Die cavity of molds l  Heavy work piece l  Failure analysis of pressure vessel, steam turbo-generator set and other equipment l  Narrow testing space where work piece installed l  Bearings and other parts l  Cases which require the test result with normalized original recording l  Material identification of the metal material warehouse l  Quick tests of large range and multipoint measuring positions for heavy workpiece Testing range see table 1 and table 2.
