Very easy to operate
* Multiple parameter measurement: Ra, Rz
* Highly sophisticated inductance sensor
* 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 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.
