General Introduction

The product is a new portable Surface Roughness Tester developed by our company.Featuring high accuracy,wide range of application, simpleoperation and stable performance. It is widely applicable in testing surfaces of all kinds of metals and non-metals. Integrating pick up with the main unit, it is a hand-held set, especially suitable for use on production sites.


 1.   Appearance using pull aluminum mould design, durable,anti-electromagnetism interference ability significant, accord with current design new trend.

  2.   By using high-speed DSP processors for the data processing and calculation, measuring and calculation speed is greatly improved.

3.    Liquid crystal adopts popular OLED display, high brightness, no perspective, wide temperature.It is suitable for various applications.

4.    Using lithium ion rechargeable batteries, it can work long hours with no memory effect.It also can work with charging .Charging time is short,while the battery life is long.

5.     Use the common USB interface to charge and communication .Use special charger or the computer USB port of chargeIt’s convenient and quick.

6.     Dot matrix LCD display, interface message is rich.

7.      Real-time monitoring of lithium battery power and display, electric charge and timely remind users.

8.       Automatic shutdown function,low power consumption and hardware design make instrument working hours exceeds.It is suitable for all kinds of field use.

9.      The sensors head has the protect door,which protect the head of the sensors effectively. Guarantee the accuracy of measurement.
