Modular TC thermometer, US style

TH51 Modular TC thermometer, US style ©Endress+Hauser

Best in class temperature measurement technology for general applications

The high modular thermometer is used for several applications in almost all industries. Examples are heat exchangers, furnaces, dryers, process reactors, etc. With different head transmitter it's a complete unit ready for use with enhanced measurement accuracy and reliability. It also enables very fast response times, due to direct contact measurement without thermowell. A variety of process connections and dimensions offer flexible application possibilities.
