Metal Surface Roughness Test Equipment Machine with Ra, Rz, Rq, Rt Main feature:
*Pocket-size & economically price
*Large measuring range suitable for most materials' the surface roughness of metal and non-metallic.
*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.
*Automatic shutdown function and low power design of software and hardware of the instrument with long working hours, suitable for field use.
*Optimized electric circuit design with transducer structure-design, high integrate power.
*It could test ex-circle, flat surface, conical surface and also test groove larger than 80*30mm.
