SHRS-450D Superficial Digital Rockwell Hardness Tester
Feature:
SHRS-450D Digital superficial Rockwell hardness tester is equipped with a newly-designed large displaying screen with good reliability, excellent operation and easy watching, thus it is a high-tech product combining the mechanic and electric features. It can show and set the present scale, test force, test indenter, dwell time and hardness conversion; the main function is as follows: Selection of all the superficial Rockwell scales; Conversion scales of different kinds of hardness; Test results can be saved and printed out, automatic calculation of maximum, minimum and average value; With RS232 interface for connecting to the computer.
Application:
Suitable for surface quenched steel, surface heat treating and chemical treating materials, copper alloy, aluminum alloy, sheet, zinc layers, chrome layers, tin layers, bearing steel and cold and hard casting etc.
Standard: ISO 6508，ASTM E-18，JIS Z2245，GB/T 230.2
