Description Overview GAOTek automatic digital micro hardness tester is a system if press the eyepiece button after measuring the indentation length, it can automatically get the hardness value and shows on the screen. With the up and down limit alarm function, test results can be saved for checking or be printed out by the built-in printer, and with RS232 interface for connecting to the computer. It can be equipped with LCD video measuring device and CCD image automatic measuring system. Features Utilizes a unique precision design combining optics, mechanics, and electronics Enhances clarity of the indentation image, resulting in clearer observations Provides more precise measurements compared to traditional methods Incorporates a digital measuring eyepiece, eliminating the need to check tables or input indentation diagonals Displays important information directly, including test mode, applied test force, indentation length, dwell time, test numbers, conversion scale, date, and time Technical Specifications Exchange Scales HRA, HRB, HRC, HRD, HRF, HV, HK, HBW, HR15N, HR30N, HR45N, HR15T, HR30T, HR45T Test force 10 gf (0.098 N),25 gf (0.245 N),50 gf (0.49 N),100 gf (0.98 N),200 gf (1.96 N),300 gf (2.94 N),500 gf (4.9 N),1 kgf (9.8 N) Turret Type Manual Loading and unloading mode Automatic Dwell Time Adjustable 0 s to 60 s Micrometer eyepiece multiple 10 x (optional 15 x) Me measurement resolution 9.84 in (0.25 µm) (drum reading) Objective magnification 10 x, 40 x Total, magnification 100 x (objective) 400 x (measurement) measurement range 5.90 in (150 µm) light source Halogen lamp (brightness adjustable) Hardness conversation Brinell, rockwell, surface rockwell Max.
