surface roughness tester

roughness tester was widely used at inspecting the processing surface of many kinds of metals and non-metal

Feature:

1 High accuracy sensor

2 Segment code LCD display, backlight function

3 using DSP chip to control and deal data, quick speed, low power consumption

4 Built-in lithium ion rechargeable batteries, high capacity, no memory effect, charging time is very short, continuous working time more than 20 hours

5 Electromechanical integration, small volume, light weight, convenient to use

6 With storage and data query function

7 standard RS232 interface can be connected with TA220s printers, can print all parameters

8 standard RS232 interface can be connected with TA220s printers, can print all parameters

9 automatic shutdown, instructions for information
