Overview:

     Portable roughness tester is a pocket-sized portable surface roughness instrument. It has high accuracy, wide measuring range, easy to operate, portable, stable, etc., can be widely used in various metal and nonmetal surface finish testing, the instrument is a sensor host integration pocket instrument, with handheld, it is more suitable for use in the production site.
Characteristics:                   
*Shell used to pull aluminum mold design, durable, anti-electromagnetic interference ability significantly, in line with the design of the new trend.
*Using high-speed DSP processor for data processing and calculation, measurement and computation speed is greatly improved.
*Liquid crystal display wide temperature using OLED color display, popular high brightness, no visual angle, is suitable for various occasions.
*The lithium ion rechargeable battery, can work for a long time, no memory effect, can while charging, charging time is short, long battery life.
* Using a dedicated charger or computer USB port for charging, convenient and quick.
*Real-time monitoring of lithium battery power and display, and to remind users to charge with charging progress indication.
