Features
- Ra, Rz, Rq, Rt 4 testing parameters.
- Large measuring range suitable for most materials, both metal and non-metallic surface;
- Using high-speed DSP processor for data processing and calculation, quick measurement and computation speed;
- Shell used to pull aluminum mold design, durable, anti-electromagnetic interference ability significantly;
- Liquid crystal display wide temperature using OLED display, high brightness, suitable for various occasions;
- Using a dedicated charger or computer USB port for charging, can work during charging, quick and convenient;
- Real-time monitoring of lithium battery power and display, remind users to charge;
- Automatic shutdown function and low power design of software and hardware of the instrument with long working hours, suitable for field use;
- suitable for more applications, testing for metal and non-metal workpiece
- The probe assembly are built in the main unit, directly measure flat surface, in grooves of 80*30mm or more, can also measure the shaft that diameter more than 22mm.
HOW TO USE -- Step 1:
Slide the measuring area to the right to expose the sensor.
Note: The sensor is a precision instrument, so it should be carefully maintained.
Avoid exposure to expansion, moisture, oil, or strong magnetic fields. After each use, gently cover the instrument with the protective cap.
HOW TO USE -- Step 2:
Place the instrument steadily on the surface of the object to be measured and press the start measurement button.
After the measurement is complete, the results will be displayed on the screen.
Note: Do not touch the instrument or the object being measured during the measurement process to avoid affecting the measurement results.
