Rich in high-quality protein and nutritious, eggs have become an essential food on our tables.

Eggshell is a perfect biological material. The quality of eggshell has an important impact on the hatching, storage and transportation, so it is particularly important to accurately evaluate the quality of eggshell.

Eggshell thickness is the earliest index used to evaluate eggshell quality and has always been one of the main indexes to evaluate eggshell quality.

However, the eggshell thickness is not uniform, the thickness of eggshell in different parts is not the same, so the eggshell thickness uniformity can be used as a property of the egg.

Eggshell thickness should be above 0.35mm generally, with good pressure resistance, long-distance transportation and easy storage.

Eggshell thickness has a great impact on the breakage rate. shell thickness 0.38mm~0.40mm breakage rate of 2%~3%. shell thickness 0.30mm~0.27mm breakage rate may be as high as 10%. shell thickness is less than 0.25mm breakage rate will be as high as 85%.

We use YUSHI PM5 Gen2 ultrasonic thickness gauge equip a special probe to measure the average thickness of the eggshell at both ends, the middle and the sharp end, accurate to 0.01mm. The measurement echo is clear, convenient and fast, and the measurement value is accurate.

Some glass workpiece including glass bottles, glass containers, glass tubes and light bulbs, as well as tubes or workpieces with small curvature can be measured by this method. If you want to learn more about using ultrasonic technology for measurement, please feel free to contact us.
