Video Hardness Measurement System

The Boeckeler VIA 110 provides the capability to measure an indentation and to determine a Knoop, Vickers or Brinell hardness value. Approximate conversions to Rockwell B or C are automatically determined. The VIA110, combined with a hardness tester, standard video camera, and monitor becomes a state-of-the-art video hardness system. For maximum accuracy, use a CID or CCD camera. The VIA-110 is compatible with monochrome and color NTSC composite cameras and monitors. With an optional VIA-RGB or VIA-Y/C interface, the VIA-110 is compatible with RGB or Y/C cameras and monitors. The VIA-110C is compatible with CCIR/PAL standards. The VIA-110 is used in microhardness testing to measure the size of the indentation and to automatically determine the hardness value. Knoop, Vickers, and Brinell hardness values are calculated using the appropriate ASTM formulas. Approximate conversions to Rockwell B and C are established using tables consistent with ASTM E 140 Tables 1 and 2 and ASTM A 370 Tables 3A and 3B, where applicable.

→ Knoop-X measurement is obtained by adjusting two vertical lines to the left and right edges of the → Knoop-Y measurement is obtained by adjusting two horizontal lines above and below the indentation.
→ Vickers measurement is achieved when two vertical and two horizontal measurement lines are used to → Brinell measurement is achieved when two vertical and two horizontal measurement lines are used to → The Knoop, Vickers, or Brinell reading with the load used to obtain calculations is displayed on screen. For → Approximate Rockwell conversions displayed on screen, if selected.
→ A labelling function features date, operator ID, lot number, sample size, load utilized, dwell time, and → A statistics table displays the count, mean, standard deviation, range, and high and low hardness values for → Nonvolatile memory stores and recalls setup information after powered down.
→ Ten scale factors are available for calibrating multiple objective magnifications.
→ RS-232 output allows users to transmit ASCII data of measurements and statistics to printers or computers. → Special RS-232 for output to Mitutoyo SPC products is accommodated, as well. Easy adjustment of the gray
