## Description

ApplicationsMeasurable workpiece range: plane, cylindrical surface, cone, bore, groove, surface, etc. (special surface to be equipped with a sensor for measurement).Working PrincipleWhen measuring the surface roughness, the sensor slides along the straight line at a constant velocity along the measured surface. The stylus touches the measured surface to generate displacement. The data is collected by the filter. The DSP calculates the output and displays the measurement result.Features●Electromechanical integration design, small size, light weight, easy to operation;●DSP chip control and data processing, high speed, low power consumption;●128×64 OLED dot matrix display, digital or graphic highlight display; no viewing angle;●Display full information, intuitive and graphical displays all parameters;●Built-in lithium-ion rechargeable battery and control circuit, high capacity, no memory effect;●Can work more than 20 hours while the power is enough;●Large capacity data storage, can store 100 item of raw data and waveforms;●Real-time clock setting and display for easy data recording and storage;●With automatic sleep, automatic shutdown power-saving features;●Reliable circuit and software design of prevent the motor stuck;●Can connected to the computer and printer；●All parameters can be printed or print any of the parameters which set by the user；●Optional curved surface pickup sensor, holes sensors, measurement stand, Sheath of sensor,extension rod,printer and analysis softwareTechnical SpecificationRoughness Parameters20 kinds(Ra,Rz,Rq,Rt,Rp,Rv,R3z,R3y,Rz(JIS),Rs,Rsk,Rsm,Rku,Rmr;Ry(JIS);Rmax)Measurement RangeThe Z axis (vertical) :160μmThe X axis (horizontal) :17.5mmResolution RatioThe Z axis0.01μm/ ±20μm0.02μm/ ±40μm

## Features

- Surface Roughness Gauge is suitable for production site, it can measure Rpk, Ra, Rz... 20 roughness parameters.
- Measures variety of surface roughness of machined parts, according to the measurement conditions and the corresponding parameters of selected, shows clearly the measurement results and graphics in liquid crystal screen , and can output on a printer, can also communication with PC.
- It is especially suitable for field inspection of large workpieces and production lines, as well as outside verification of inspection, measurement and commodity inspection departments.
- The roughness measuring head uses high precision inductance sensor, and the measurement value is stable and accurate.
- The curved surface sensor can be selected to measure the roughness of concave and convex surfaces, and the inner hole roughness can be measured by the small hole sensor.
