Introduce:

Model HR-150DT  Rockwell Hardness Tester automatic unloading mechanism with adjustable total test force dwell time potentiometer, rotary converters test force transformation by the Dutch handwheel obtained, so the operation easily and quickly , in addition to dial zero, there is no human operator error, high sensitivity, stability, suitable for workshops and laboratories.
Rockwell hardness measurement applies to all kinds of metal materials.Its principle is at the beginning of trial test force and total test force has the role of the indenter into the surface of the sample, removable main test force, measuring the depth of the indentation residual reserves at the beginning of the test force.

Features:
Optional with Rockwell hardness scale; having hardness scale conversion option; hardness test hold time can be selected from between0~ 99s; having reset function; hardness test results printout; hasRS-232Cserial communication port for user extensions
