Split Type Surface Roughness Tester KR310
Split Type Surface Roughness Tester KR310 is a handy mobile surface roughness tester with external drive unit, to which the stylus drive unit can be stored within its main unit for standard measurement, or separated from the display unit by using the supplied cable which allows more flexible measurement in any orientation. The driver can be separated and reattached in one simple step. It uses DSP chip control and data processing, features high speed, low power consumption.
Split Type Surface Roughness Tester KR310 include height support feet, adapts measuring height and guarantees stable and flexible. KR310 can show stylus position on testing page for convenience to check and adapt stylus according to it.
