overview
Portable roughness Tester is a portable stylus surface roughness shape measuring instrument, which is suitable for the detection of workshop verification stations, laboratories, measurement rooms and other environments. The measurement parameters are in line with international standards and compatible with the standards of some industrially developed countries such as the United States, Germany, Japan, and the United Kingdom. Measurement results can be displayed numerically and graphically
It is displayed on the LCD display and can also be output to the printer.
The upgrade has been improved in the following areas:
Using lithium-ion rechargeable battery, it can work for a long time, no memory effect, can work while charging, short charging time, and long battery life.
The working performance of the circuit is improved, the operating Voltage is reduced, and the power consumption and circuit noise are reduced accordingly.
The driving mechanism, materials and processing technology of the sensor have been improved, and the assembly is more accurate and the measurement is more stable.
The newly designed display interface adds some necessary measurement hints and low Voltage hints.
The sensor interface has been improved to make the sensor more accurate and tightly inserted into the main unit to ensure the accuracy of the measurement process.
The LCD backlight function is added, which is convenient for users to use in dark places.
Smaller size and lighter weight.
