The main function
The pocket surface roughness meter is a new intelligent instrument specially used to measure the surface roughness of processed parts. This instrument integrates today's microprocessor technology and sensing technology. It uses a professional microprocessor and optimized highly integrated circuit design to form an ultra-small architecture that adapts to the development trend of today's instruments. It can complete the measurement of roughness parameters. Acquisition, processing and display work. It is suitable for processing industry, manufacturing, testing, commodity inspection and other departments, especially for on-site inspection of large workpieces and production lines, as well as outbound verification of testing, measurement, commodity inspection and other departments. Not only can it measure outer circles, flat surfaces, and conical surfaces, it can also measure grooves whose length and width are greater than 80Ã30mm.
The main function
The shape is made of ABS engineering injection molding, which is sturdy and durable, has remarkable anti-electromagnetic interference ability, and is in line with today's new design trends. Compared with the previous metal shell painting process, ABS engineering plastics will not peel off the paint, and the appearance is better preserved.
Using a high-speed DSP processor for data processing and calculation, measurement and calculation speed are greatly improved.
The display LCD adopts the popular OLED display, with high brightness, no Viewing Angle, and wide temperature, suitable for various occasions.
Using lithium-ion rechargeable battery, it can work for a long time without memory effect. It can work while charging. The charging time is short and the battery life is long.
Dot matrix LCD display, rich interface prompt information.
Real-time monitoring and display of lithium battery power, promptly reminding users to charge and providing charging progress prompts.
The automatic shutdown function and low-power consumption software and hardware design make the instrument work for a long time and is suitable for various on-site uses.
The sensor probe has a protective door, which effectively protects the sensor probe and ensures measurement accuracy.
