SRT-6223HandheldRoughness measuring instrument

■Product Introduction:accord withASTM D4417methodCandNACERP0287-95Testing method that can directly measure the peak of the surface-The height of the valley floor is suitable for industries with surface roughness requirements such as shot blasting, printing, and spray anti-corrosion industries. Based on the selected measurement conditions, the corresponding parameters are calculated and displayed clearly on the LCD monitor. When measuring the surface roughness of a workpiece, the instrument sensor is placed on the measured surface of the workpiece, and the sharp stylus embedded in the instrument senses the roughness of the measured surface. At this time, the roughness of the measured surface of the workpiece causes displacement of the stylus, which changes the inductance of the sensor inductance coil. As a result, an analog signal proportional to the roughness of the measured surface is generated at the output terminal of the phase sensitive rectifier. After amplification and level conversion, the signal enters the data acquisition system,DSPThe chip will perform digital filtering and parameter calculation on the collected data, and the measurement results will be displayed on the LCD screen, which can also be integrated withPCMachine communication enables data analysis, statistics, and printing.

◆ High precision inductive sensor;

◆ Integrated design, small size, light weight, easy to use

◆ It has an automatic shutdown function.

This instrument has two shutdown modes, namely manual shutdown and automatic shutdown. At any time, simply press the multifunction button lightly Key, wait for it to appear on the monitorOFFRelease your hand to manually turn off the power of the entire machine; on the other hand,If in1If no button is pressed or any measurement is taken within minutes, it will automatically shut down to achieve power-saving function.
