เครื่องวัดค่าความขรุขระของผิว ความหยาบของผิว

(Surface Roughness Tester (Ra, Rz))

(Model: SRT-6200)

ราคาพิเศษ 30,000 บาท


This multi-parameter tester designed to measure 2 parameters (Ra, Rz) using the built-in Diamond pin probe. This terster is widely used in production site to measure surface roughness of various machinery-processed parts and calculate corresponding parameters according to selected measuring conditions and clearly display all measurement parameters in Metric or Imperial. It also have 4 wave filtering methods (RC, PC-RC, GAUSS & D-P). In addition, said parameters can be downloaded directly to PC as well via the optional RS-232 CD software & cable and passed ISO, DIN, ANSI and JIS international standards.

Easy measurement can be done by placing the sensor on the surface then uniformly slide the highly sensitive 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 then outputs the results clearly on LCD
