Paul N. Gardner USA, described as worldwide distributors, producers, and designers of quality physical and inspection instruments for the paint, coatings, and related industries, is introducing the Depth Gauge as its latest product offering.: 

Used for measuring thickness of open and closed cell foam, the gage allows commercial roofing contractors and spray polyurethane foam (SPF) applicators to test the depth of the foam quickly and easily while applying to a roof substrate.

This gage is also designed for measuring the depth of spray fire resistive material (SFRM) fireproofing material to ensure consistent depth from one area to another.

Constructed of sturdy plastic and weighing in at only 1 lb (0.45 kg), this gage can read depths up to 5.75 in (14.60 cm).  It has an easily adjustable stainless-steel pin and easy to read numbers.

On July 1, 2019, the Paul N. Gardner Company became part of the Altana family after being acquired by the Byk-Gardner/Altana Group. Many GARDCO employees have been with the company for 20-30 years, and according to the company, they share the same key values of appreciation, openness, empowerment, and trust that are a major part of Altana’s vision. 

As such, GARDCO says Altana shares the core values and industry standards that have made its name synonymous with quality for physical testing equipment. “We are confident that our combined strengths will provide new and innovative solutions to improve quality testing worldwide,” the company said in a statement.
