multi-parameter testing machine / ballpoint pen / automatic / mechanical
This writing industry machine is capable of simultaneous testing of 10 refills in various writing angles that range from 90° to 60° under a 80 - 120 gr (0.176 - 0.265 lbs) load. It provides assistance in the investigation of affinity, wear rate, lay-down and flow character at various writing speeds. It also checks for the sphericity of balls, starting abilities as well as other parameters. Its registering mechanism allows the writing distance to be read in meters. The writing speed and paper feed can be adjusted, allowing a very efficient testing.
