What started out as a one-man operation based on curiosity, has since evolved into MadgeTech, a leading manufacturer of data loggers worldwide. As MadgeTech has grown, we have never lost sight of President, Norm Carlson’s, original vision of a company that maintains meaningful customer relationships and manufactures the highest-quality data loggers on the market.

At MadgeTech, we take pride in maintaining our production process entirely out of our headquarters in Warner, New Hampshire. Our data loggers are designed, assembled and packaged under the same roof, guaranteeing the highest level of quality. MadgeTech is proudly known as an industry expert with our solutions sold in more than 100 countries around the world.

As MadgeTech looks to the future, we will continue to harness new technologies and rely on customer feedback to create the innovative data loggers and software we are known for. We are proud to remain ahead of the curve in the development of wireless technology, cloud services and real-time monitoring, all while providing customers with the tools needed to aid in regulatory compliance.
