Features:
● 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.
● Small in size, light in weight and easy to use.
● Can communicate with PC computer for statistics, printing and analyzing 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.
● Metric / Imperial Conversion.( SRT-6210 )
