The performance advantage

• 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 excircle, 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.
