Origin	Hong Kong
Model Number	SRT-6200

SRT-6200 multi-parameter tester designed to measure 2 parameters (Ra & Rz) and is compatible with four standards of ISO, DIN, ANSI and JIS and is widely used in production site to measure surface roughness of various machinery-processed parts, calculate corresponding parameters according to selected measuring conditions and clearly display all measurement parameters. It has a measuring range of 0.05-10.00um / 1.000-400.0uinch for Ra and 0.020-100.0um / 0.780-4000uinch for Rz and calculates results according to the parameter you select. When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism inside the tester. The sensor gets the surface roughness by the sharp built-in probe. This roughness causes displacement of the probe which results in change of inductive amount of induction coils so as to generate analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier. The exclusive DSP processes and calculates and then outputs the measurement results on LCD. The large LCD shows roughness in either Ra or Rz at the touch of a button.
