Click for Spec Sheet

Improve your quality control without hurting your bottom line.  Scienscope's    CO-VM-S20 is an affordable, yet highly accurate measurement system. 


 AVM20 software is a PC-based field of view dimensional measurement software that turns a conventional microscope into a powerful measurement station. The software uses the latest digital image processing technology to analyze video images for dimensional measurement. It then compares the measurement to nominal values and tolerances to identify conditions of non-conformance. The software can also be integrated to your application.

The software is for Windows 95, Windows 98 and Windows NT 4.0. It takes advantage of the latest operating systems and provides you a familiar, graphical environment to complete your measurement. The software can be easily linked to other Windows applications, such as spreadsheets and SPC packages. The AVM20 tolerance functions conform to ASME Y14.5M 1994.

The software is designed for image documentation, product inspection and quality control. The software provides a full range of functions for image capture, measurement, archival, image comparison, image and result output. The software is easy to use and it will deliver reliable and repeatable precision measurement results on the hardware of your choice.

Video Card

A video card is used to transfer the image to the PC monitor, where an accurate measurement can be achieved using the AVM20 Software.  The Video Card incorporates an on-board 3D accelerator and 8 MB of fast SGRAM. Its 128-bit memory interface is capable of running at speeds up to 125 MHz, allowing for display resolutions up to 1600x1200 at 85 Hz.
