RHL50 LCD Display Backlight Portable Rockwell Hardness Tester

Portable Hardness Tester RHL50 rockwell hardness tester

Features

LCD display of 128×64 matrix with backlight, showing all functions and parameters. Converts to all common hardness scales (HV,HB,HRC,HRB,HRA,HS). English displaying and easy and convenient menu operation. Powerful PC Software available and USB 2.0 interface. 7 types of Impact Device optional, which don't need to be recalibrated when changing them. Memory of 600 groups data(impact times:32～1). Lower limit setting and sound alarm. 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. In-built Smart Li lon rechargeable battery while USB connected and charging controlling circuit. Inbuilt function of Software Calibration. Two ways of switching off by key and automatically
