Part No: ROTE-3002

 

Surface roughness tester is the machine which used to measure the roughness of the surface using probes.

Features:   

 *    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.
