Advantages
►The roughness of metal and non-metallic surface
►Pocket-size & economically price
►Large measuring range suitable for most materials
►Features external calibration at keyboard
►Optimized electric circuit design with transducer structure-design,high integrate power, driver and display.
►Select freely with Ra,Rz, Rq, Rt parameters.
►It could test ex-circle, flat surface, conical surface and also test
groove with length and width larger than 80*30mm
Main Function:
►Shape 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.
►Charging and communication using the common USB interface. Using a dedicated charger or computer USB port for charging, convenient and quick.
►Dot matrix liquid crystal display, interface prompt information rich.
►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.
