Product Feature：
lPortability and environmental adaptability are strong: The handheld design is small in size (141×55×40mm) and weighs approximately 400g. It is suitable for various scenari- os such as workshops and laboratories, and can operate stably in an environment ranging from -20℃ to 40℃.
lExcellent measurement performance: 160 μm large range, maximum resolution of Z-axis 0.001 μm, indication error ±(5 nm + 0.1 A), indication variation ≤ 3%, reliable accuracy;
lWide compatibility with parameters and standards: Includes basic parameters such as Ra and Rz, as well as advanced parameters like RPc and Rk. Compatible with multiple na- tional standards including ISO, ANSI, DIN, and JIS, meeting diverse measurement requirements.
lEasy operation and display: 128×64 OLED screen shows all parameters and graphics. The key definitions are clear. It supports switching between Chinese and English. It can au- tomatically enter sleep mode and shut down for power saving.
lLong battery life and storage capacity are excellent: The built-in lithium battery can provide up to 20 hours of power, supports USB charging, and can store 100 sets of raw data and waveforms, with real-time clock recording.
lExtensive functionality and durability: The all-metal housing is sturdy and can be connected to computers / printers. Op- tional curved surfaces, small holes, and other specialized sensors and measurement platforms are available, making it suitable for complex measurement scenarios.
Product Application：
