A brief introduction of T&D

Company Profile

T&D History

Since our beginnings in 1986, T&D has been committed to being the most trusted name in the data logger industry. We remain at the forefront of innovation, which now includes meeting our customer’s demand for "anytime anywhere access" to data. Reflective of our commitment to customer support, data collected by our very first data logger can be read with T&D software today.

T&D's data logging systems based on wireless communication and LAN or mobile networking, coupled with the introduction of our free and unlimited cloud-based “T&D WebStorage Service,” are clear examples of our dedication to staying on the leading-edge. With a variety of models and connectivity options, our devices meet the measurement needs of just about everyone.

T&D currently has over 80 distributors over three continents worldwide and head offices in both North America and Europe. Our data loggers are used in almost every type of industry and are relied on by companies like Boeing, Sony, The Smithsonian Institute, Intel, Siemens, and Home Depot to name a few. There are numerous data logger suppliers in the world today, but none with the wealth of experience and dependable reputation that T&D has earned over two decades.
