Back Connect Large Industrial Thermometer 3″ dial, Material 304 Stainless Steel. Various stem lengths available.
The Tel-Tru GT300R is a 3″ dial back-connected industrial bi-metal thermometer built for robust process measurement in demanding environments. With a 304 stainless steel construction, ½″ NPT connection, and pointed tip stem, the GT300R delivers accurate temperature readings with the reliability Tel-Tru has maintained since 1916.
The back connection makes the GT300R well suited to panel mounting and installations where the instrument faces directly outward from the process connection point. Field recalibration is straightforward via the built-in recal feature. NSF certified and NIST traceable.
