## What is VacPuc?

VacPuc is a wireless, batteryless pressure sensor for measuring vacuum bag pressure in composite manufacturing processes – resin infusion/VARTM, and both OoA and autoclave prepreg.
VacPuc is powered by inductive power transfer from a standard mobile phone and data is displayed and logged on an easy-to-use mobile app.

A vacuum leak check is one of the fundamental quality assurance checks in composite manufacturing, yet the industry-standard method requires a bag penetration, which itself is a high-probability leak point. VacPuc removes the requirement for a bag penetration to measure the vacuum and perform a vacuum leak check.
