Polarimeter KERN OAB 10LN

Application: This ultrasound hardness testing device is ideally suited for mobile hardness testing, where the main emphasis is on obtaining rapid and precise results Principle: The SAUTER HO measures by using a vibrating rod which vibrates at ultrasonic frequency and is pressed onto the sample at a defined test force. At the lower end there is a Vickers indenter. Its resonant frequency increases, as soon as an indentation is created when it comes into contact with the sample. Through appropriate adjustment of the device, the resulting change in resonant frequency is matched with the corresponding Vickers hardness Examples: The SAUTER HO ultrasound hardness testing system is primarily used for measuring small forgings, castings, welding points, punched parts, casting tools, ball bearings and the flanks of gear wheels as well as for measuring the influence of warmth or heat Advantages compared with Rockwell and Brinell: Almost nondestructive testing by smaller test force and thus only microscopic indentation craters Advantages compared with Vickers: Demanding optical measuring is not required. You can therefore carry out measurements directly onsite, for example, on a permanently installed workpiece Advantages compared with Leeb: The high requirements concerning the proper weight of the test object can be widely omitted Standards: The device meets following technical standards: DIN 501591 ASTMA10382005 JB/T93772013 Measurement data memory saves up to 1000 measurement groups each with 20 individual values Mini statistics function: Display of the measuring result, the number of measurements, the maximum and minimum value as well as the average value and the standard deviation Calibration: The device can be set to both standard hardness test blocks as well as to up to 20 reference calibration values. When doing this it is possible to measure different materials quickly, without having to readjust the device to the individual materials Scope of delivery: Standard block for calibration (approx. 61 HRC), USB cable, Display unit, UCI sensor unit, transport case, software to transfer the saved data to the PC, protective case (turquoise), further accessories ,Optical rotation -180° – +180° Division 1° Nonius 0,05° Wellenlänge 589 nm Lupenvergrößerung 3 x Plug-in power supply type Built-in power supply Net weight approx. 3,6 kg Dimension (W×D×H) 500×130×330 mm Product family OAB-L
