Digital Rockwell Hardness Tester

HRS-150 Digital Rockwell hardness tester adopts the high resolution color touch screen, it can show and set the present scale, test force, test indenter, dwell time and hardness conversion. The instrument adopts the dead weight loading mechanism. During operation, do the manual pre-loading until it beeps, the instrument will automatically load, dwell, unload, and display the hardness value. The operation is convenient and the display is intuitive.

• The main body adopts cast iron structure which minimizes the deformation. The shell has undergone natural aging treatment for more than half a year, and its physical properties are stable.
• After heat treatment, the hardness of the lifting screw reaches 35~40HRC, which has stable structure and wear resistance.
• The weights and lever are manufactured and calibrated by classic techniques, with high accuracy and can be fine tuned through mechanical structures.
• 5.6 inch HD touch screen display and operation, dynamic image display of operation process and beeping prompts.
• It supports for Rockwell hardness scales, after selecting the scale it prompts the selection of corresponding indenter and test force, and the test force is switched by rotating the knob.
• It supports the conversion of various hardness scales in real time.
• It supports upper and lower limit settings and has the function of arc correction compensation.
• Real time saving of hardness test results, automatic calculation of maximum, minimum, mean, standard deviation, repeatability, etc., with multiple folder selection, optional deletion and printing output.
• Built in thermal printer with fast printing speed, and equipped with USB interface for users to output the data.

Suitable for quenched steel, tempered steel, annealed steel, cold and hard casting, malleable cast iron, hard alloy steel, aluminum alloy, copper alloy, bearing steel etc.
