    Laser Diameter Gauge, Single Axis, 1-100mm

    Cost-effective laser diameter gauge with a measurement range of 1mm to 100mm is a single-axis device designed for determining the diameter of cylindrical objects such as wires, cables, tubes, and rods. Utilizing laser technology, it precisely measures the diameter by assessing the shadow cast by the object as it passes through the laser beam.

    Tips: How to choose a suitable laser diameter gauge?

    There are several key factors to consider when choosing a suitable laser diameter gauge:

    1. Measuring range: Make sure the measuring range of the instrument covers your actual needs, including both the minimum and maximum diameters.
    2. Measuring accuracy: Choose a laser diameter measuring instrument with suitable measuring accuracy based on the specific requirements of the application. High-precision measuring instruments are usually more expensive, but they are necessary in demanding applications.
    3. Response speed: In dynamic measurements, the response speed is an important factor to ensure that the instrument can capture rapidly changing diameters in real time.
    4. Environmental adaptability: Consider the adaptability of the instrument in different working environments, such as temperature, humidity, vibration, etc.
    5. Data output and processing: Check the data output options and interfaces of the instrument to ensure that it is compatible with your data acquisition and processing system.
