Eggshell Thickness Gauge


The Egg Shell Thickness Gauge (ESTG) is an extremely precise high-resolution non-destructive device for measuring egg shell thickness. It measures the thickness of an egg shell without breaking the egg using precision ultrasound.

The gauge has a sturdy extruded aluminum housing which is sealed for excellent environmental protection, ensuring trouble-free use even in the toughest field and production environments.
