For cost considerations, some manufacturers choose more cost-effective Thickness Gauges for film thickness measurement. The GM200 and GM210 coating Thickness Gauges represented by domestic Biaozhi are among the most discussed topics.
In this issue, NBCHAO provides you with a comparison of these two Thickness Gauges, and provides systematic comparison opinions for customers to choose GM200 or GM210.
Product Image Comparison
It can be seen from the picture that GM200 is orange, and GM210 is beige. They are the same in size and shape, and they belong to the same series of coating Thickness Gauges. Please see Table 1:

technical comparison
The GM210 coating Thickness Gauge can measure the minimum diameter of the substrate up to 12mm, while the GM200 can only measure the minimum diameter of the substrate at 50mm. The minimum thickness requirement of both substrates is 0.5mm. For other parameters, please refer to the following table 2:
