FAQ
1. What is the measurement accuracy and which scenarios is it suitable for?
Answer: The standard model offers a measurement accuracy of ±0.2° and a resolution of 0.05°. It is suitable for woodworking cutting, construction leveling, machinery calibration, outdoor engineering slope measurement, home crafts, and other scenarios, meeting both professional and daily use needs.
2. What are the dimensions and weight of the device? Is it easy to carry?
Answer: The mini version typically measures 56 x 54.6 x 27.5mm (similar in size to a phone charm) and weighs only 40-60g. It can be easily placed in a pocket or toolbag, making it hassle-free for high-altitude operations, narrow-space work, or outdoor mobile measurements. Its portability far exceeds that of traditional angle gauges.
3. Does it have a magnetic function? Which surfaces can it attach to?
Answer: It can firmly attach to ferromagnetic metal surfaces such as iron and steel, freeing up your hands during measurement. It is particularly suitable for angle detection of metal workpieces like mechanical parts, steel structures, and pipelines.
4. Can the display be clearly seen in strong light or dim environments?
Answer: Equipped with a high-brightness LCD display, some models feature a backlight function that can be activated with a button press. In strong light, readings can be taken by adjusting the device angle; in dim environments (such as tunnels or indoor corners), the backlight ensures clear visibility, avoiding parallax errors.
