Meet ISO, ANSI, DIN and JIS standards with RT 2200, a portable material surface roughness testing device with an easy-to-read LCD display, large internal memory and convenient USB port. Software is included to allow data transfer to a PC. Ideal for taking quick and accurate measurements of surface texture roughness, the RT 2200 roughness tester uses a digital signal processing (DSP) chip for high-speed data processing and control with low-power consumption.
