Bottle Wall Thickness and Material Distribution Tester

Non-contact thickness gauge with a magnetic ball probe that scans blown PET bottles for sidewall, shoulder and base thickness. Used by bottle blowers to optimise material distribution and cut resin weight without losing strength.

Specification

A steel ball on the inside of the bottle and a Hall-effect probe outside measure the gap, which equals wall thickness. Readings are taken at various heights to build a thickness profile. The profile guides adjustments to preform design and blowing parameters.

Features

• Hall effect probe with magnetic ball target
• Measures from 0.05 to 3.0 mm wall
• Multiple point profile storage and print
• Fits bottle neck diameters from 22 mm
• Sub-micron resolution display
