General Description
The RH-45AUTO (superficial) Modular Rockwell hardness testers are accurate advanced instruments distinguished by their friendly operation, high accuracy, repeatability, reliability, and versatility. They are used for testing the hardnesses of a variety of metals in different locations. They are automatic test machines built with precise force sensors, force monitoring electronics systems, and depth measurement systems. The RH-45AUTO are made up of a main unit and a set of frames. Each frame is specialized for holding a certain test specimen shape or size. By switching frames on the main unit, you can easily form specialized testers.
The RH-45AUTO can directly measure and produce 15N, 30N, 45N, 15T, 30T, and 45T readings, and can convert to HV and HB scales. The hardness tester has Bluetooth and USB capabilities for sending test results to a Bluetooth printer or PC.
1. The RH-45AUTO are automated testers. Do not touch any movable parts of the tester, such as the indenter, when the tester is operating or injury may occur.
2. Before beginning a test, ensure the indenter is placed in the position sleeve. Otherwise the displacement sensor will be damaged. The tester has a safety feature to detect if the indenter is missing. If so, the presshead will automatically move backwards, and “No Indenter” will FLASH on the display.
3. The presshead and indenter cannot move forward more than 25mm. Any attempt to advance the presshead forward more than 25mm or retract the pressback backward before the starting position will turn off the motor. Use a smaller retaining frame or reposition the tester on the column stand if the test specimen is too small.
