The newly designed frame provides maximum clearance for positioning the workpiece.  
A flat table is all that is needed for mounting these testing machines.
Simple to operate
The Dial Model HR-210 features an automatic preset 
function on the indicator to set the initial (Minor) test 
force to zero.
Motorized application of the total (Major) 
test force improves accuracy and repeatability 
and eliminates the problems of an oil dashpot 
controlled system.
Rockwell Hardness Testing Machine
Order No. 963-220-10A
Manually handles test force and preliminary 
test force selection. Motor drive controls 
loading sequence.
