SRT-6223 handheld roughness measuring instrument Introduction
SRT-6223 handheld roughness tester conforms to ASTM D4417 method C and NACERP0287-95 test method, can directly measure the peak-bottom height of the surface, suitable for: shot blasting industry, printing industry, spray anti-corrosion industry and other surfaces Used by industries that require roughness, the corresponding parameters are calculated according to the selected measurement conditions, and all measurement parameters are clearly displayed on the LCD. When measuring the surface roughness of the workpiece, the instrument sensor is placed on the surface of the workpiece to be measured, and the roughness of the measured surface is sensed by the sharp stylus built in the instrument. The inductance of the sensor inductor changes, so that an analog signal proportional to the measured surface roughness is generated at the output of the phase-sensitive rectifier. The signal is amplified and level-converted into the data acquisition system. The data is digitally filtered and the parameters are calculated. The measurement results are displayed on the liquid crystal display. At the same time, it can communicate with the PC to achieve data analysis statistics and printing.
Features
1.High-precision inductive sensor;
2.Integrated design, small size, light weight, use
3.With automatic shutdown function.
4.The instrument has two shutdown methods, namely manual shutdown and automatic shutdown. At any time, just press the multi-function key lightly, and when the display shows OFF, release the hand to manually turn off the power of the machine; on the other hand, if no key is pressed within 1 minute, If no measurement is taken, it will automatically shut down to achieve power saving.
5.With metric and inch conversion function.
6.With average value calculation function.
