Bench hardness tester NR3D
Rockwell hardness tester with reading also in the Brinell scale (HB 30 for steel and HB 10 / HB 5 for aluminum and light alloys) precise and reliable, for items of small and medium dimensions. ASTM E 18, EN ISO 6506.
Product advantages
Available in Rockwell and Super Rockwell version
Optimal for the control of plastics
Absence of penetrator and penetrator shroud
Allows the measurement of small parts and is ideal for the control of spheres or composite materials
Brinell loads
Allows Brinell measurements to be made using the available Brinell penetrators
Measuring head removable from the stand
Faster overhauls and calibrations
Robustness and ease of use
Ideal for the use in schools
Low investment
The low price allows the amortization of the expense in a short time
