When choosing a flash meter, there are several factors to consider in order to pick the best device for your needs. Here's a quick one-minute guide to selecting a flash meter.

The size of the product determines the size of the flash meter's measuring platform

A. Smaller products may require a flash meter with a smaller measuring platform, such as a model suitable for measuring smaller products.

B. Larger products require a flash meter with a larger measurement platform to ensure that the product can be placed completely on the measurement platform for measurement.

Example: For small electronic components, a flash meter with a smaller platform (IMAGE 3) may be sufficient, whereas for large mechanical parts, a flash meter with a larger platform (IMAGE 3 plus/IMAGE 3 pro, etc.) may be required.

Measurement requirements, measurement of 2D flat dimensions / 3D contour measurement

A. If you need to measure the 2D flat dimensions of a product, then a flash meter that specializes in 2D measurements (IMAGE 3 plus/IMAGE 3 pro, etc.) is sufficient.

B. These flash meters are usually able to quickly and accurately measure the length, width, diameter and other flat dimensions of a product.

Example：if you need to measure the 3D contour of a product, you need to select a flash meter with 3D contour measurement capability (IMAGE 3 MAX, IMAGE 3 MAX2). This type of flash meter can obtain the 3D shape information of the product, which is very helpful for the measurement of products with complex shapes.

High-precision measuring lenses: telecentric lens / zoom lens

A. The telecentric lens is characterized by parallel light imaging, which can reduce the measurement errors caused by changes in the position of the object, and is suitable for measurement scenarios with high requirements for accuracy.

B. The zoom lens, on the other hand, can adjust the magnification according to different measurement needs, with higher flexibility. When choosing, you can decide whether to choose the telecentric lens or the zoom lens according to the specific measurement task and accuracy requirements.

When choosing a flash meter, it is important to consider factors such as product size, measurement needs, and measurement lenses in order to quickly select the most suitable flash meter for you and improve measurement efficiency and accuracy.
