  • 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.
