The performance advantage
Ø The roughness of metal and non-metallic surface
Ø Pocket-size & economically price
Ø Large measuring range suitable for most materials
Ø Features external calibration at keyboard
Ø Optimized electric circuit design with transducer structure-design,high integrate power, driver and display. 
Ø Select freely with Ra,Rz, Rq, Rt parameters.
Ø It could test ex-circle, flat surface, conical surface and also test groove with length and width larger than 80*30mm.
Main Function:
v Shape used to pull aluminum mold design, durable, anti-electromagnetic interference ability significantly, in line with the design of the new trend.
v Using high-speed DSP processor for data processing and calculation, measurement and computation speed is greatly improved.
v Liquid crystal display wide temperature using OLED color display, popular high brightness, no visual angle,, is suitable for various occasions.
v The lithium ion rechargeable battery, can work for a long time, no memory effect, can while charging, charging time is short, long battery life.
v Charging and communication using the common USB interface. Using a dedicated charger or computer USB port for charging, convenient and quick.
v Dot matrix liquid crystal display, interface prompt information rich.
v Real-time monitoring of lithium battery power and display, and to remind users to charge with charging progress indication.
v Automatic shutdown function and low power design of software and hardware of the instrument with long working hours, suitable for field use.
