Tramex are International Leaders in the Design and Production of Moisture Meters, with a reputation for the highest standards in quality and innovation. Our heritage in innovation began with our foundation in 1974. Inspired by our experience and knowledge of building moisture inspection, and working closely with Trinity College Dublin, one of the world’s leading research-intensive universities, we invented, patented and developed the first ever non-destructive moisture meters.

These award-winning products gave professionals unique and advanced ways to inspect the entire building envelope. In addition to delivering deeper and more accurate readings than any other product available, these meters also made it possible to detect and trace the source and extent of moisture problems without causing any damage to the material being tested.

Today Tramex continues to innovate, design and manufacture moisture meters for building inspection to the highest standards of precision and durability in a variety of industries such as Flooring, Walls & Roofing, Water Damage Restoration, Indoor Air Quality, as well as for material specific industries related to Wood and Concrete. We have the most advanced range of instruments for detecting, tracing and measuring moisture in the building envelope, and are market leaders in the many industries we serve.

Designed with the professional in mind, each instrument is manufactured in Ireland and is individually tested with exacting precision for accuracy and durability. Every Tramex Meter is then individually calibrated ahead of shipping.

With in-built quality you can trust, we know that each investment in a Tramex Meter is an investment in quality and peace of mind for years of trouble-free use.
