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