The manually operated HR-150A Rockwell hard ness tester is highly appreciated for its perfection and very easy operation. This machine uses the standard preliminary test force of 10kgf and main –
loads of 60/100/150 kilograms conform the international
Rockwell standard. After each test the HR-150A shows the
Rockwell B or Rockwell C hardness value directly on the
dial indicator. The preliminary test force has to be applied
manually, followed by applying the main load by means of the
lever at the right side of the hardness tester. After unloading
the dial indicates the requested hardness value directly with high accuracy and
repeatability.
HR-150DT Motorized Rockwell Hard ness Tester features high measuring accuracy,reliable performance and appli cable to wide fields.By adopting the motor – –
driven automatic loading and unloading technique,that
thoroughly eliminates human error in thoes operations.
HR-150DT serves to measure the hardness of hard
metals,carburized steels, quenched steel,hardcast iron,
mild steels,Al-alloys,Cu-alloys and malleable irons.

The HRS-150 d Rockwell standard. It obseverd digital display device and micro computer control lifting and lowering screwied and automatic feedback lock among rotary wheels,connecting outside to the printer, full realizes the automatic.That completely eliminates error in those operations and reading. igital Rockwell hardness tester is an organic whole of mechanical and electrical hardness testing instrument,with its novel appearance,directly is designed for ease of use and safety in operation, and conforms with the international It
can used to measure the Rockwell hardness of ferrous,nonferrous metals and plastic materials.
