Surface Roughness Tester M/I

When measuring the roughness of a surface with the SHGLST022 Surface Roughness Tester 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 thenoutputs the measurement results on LCD.

features

• This instrument 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 condition and clearly display all measurement parameters.
• Multiple parameter measurement: Ra, Rz, Rq, Rt
• Highly sophisticated inductance sensor
• Four wave filtering methods : RC, PC-RC, GAUSS and D-P
• Built-in lithium ion rechargeable battery and control circuit with high capacity
• Can communicate with PC computer for statistics,printing and analysing by the optional cable and the software for RS232C interface.
• Manual or automatic shut down. The tester can be switched off by pressing the Power key at any time. On the other hand, the tester will power itself off about 5 minutes after the last key operation.
• The tester can memorize 7 groups of measurement results and measuring conditions for later use or download to PC for analyzing and printing.
• Metric /Imperial Conversion
