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
