MadgeTech data loggers are small, battery powered, electronic devices that record measurements of physical parameters such as temperature and humidity. This data is stored or transmitted for analysis to allow users to verify the environments being monitored. This process is vital for many applications such as cooking, storing, shipping or even sterilization. The recorded data, in many cases, is mandated by regulations for verification of product quality or consumer safety.

All MadgeTech data loggers are engineered, manufactured, and serviced in the Warner location.
