The egg shape index meter FHK NFN385 Japan Fuji is mainly composed of two parts: an egg fixing frame and an egg shape measuring rod. The egg shape index is automatically calculated according to the calculation formula while measuring the length of the longitudinal diameter and transverse diameter of the egg.

Purpose: 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.

Technical parameters:
■ egg shape index = egg longitudinal diameter (long diameter)/egg transverse diameter (short diameter)
■ The results of this egg shape tester are shown to have two methods: egg shape number (60-100) and number (0-8). egg-shaped number
Egg shape number = egg transverse diameter (short diameter)/egg longitudinal diameter (long diameter) X100
Egg shape index = 1/egg shape number X100
