The egg shape index meter is Bulader-3A used to determine the egg shape index of eggs. The use of this instrument can be deduced whether the shape of the egg is oval, or partial round like spherical, or slender cylindrical.

Parameters:

■ egg shape index=Egg longitudinal diameter (long diameter)/Egg transverse diameter (short diameter)

■ The egg shape tester shows the egg shape number (60-100) and the numbering of the egg-shaped number (0-8) two methods.

egg-shaped number=Egg transverse diameter (short diameter)/Egg longitudinal diameter (long diameter)X100

egg shape index=1/egg-shaped numberX100

egg shape index normal range:1.24—1.37(If the measured egg shape index is within this range, it means it is a normal egg shape)
