Tel-Tru

Tel-Tru Manufacturing Company is a leading manufacturer of bimetal thermometers, temperature instruments, and pressure gauges. For over 75 years Tel-Tru has been producing world-class thermometers and related instrumentation.

Serving industrial, laboratory, and the food service markets Tel-Tru offers a variety of thermometers to meet any needs. Styles include bimetal, gas actuated, vapor tension, surface, mercury in glass industrial, and non-contact infrared. Tel-Tru's bimetal thermometers are available in head sizes ranging from 1 ¾" to 5" in either bottom connected, back connected, or adjustable angle designs. With all 304SS construction the adjustable angle design allows for 360° rotation of the head as well as tilting on a 180° arc.

For both direct and remote mount applications, the gas actuated thermometers offer high accuracy with low ambient error. Tel-Tru's molecular sieve design, utilizing inert gas and activated carbon, produces much lower internal pressures than conventional gas thermometers. This contributes to their extreme overrange capabilities.

Tel-Tru's other offerings include the vapor tension design for remote reading applications. These thermometers offer excellent accuracy both above and below ambient. Also available are the surface mount thermometers for measuring surface temperature and the Tel-Fast hand-held, battery operated, non-contact thermometers.

Additionally, Tel-Tru also offers a wide variety of thermometer accessories. Thermowells are available for pressure, corrosive fluids, and high velocity applications. These are available in brass, carbon steel, both 304 and 316SS, and Monel with threaded, flanged, sanitary, and socket weld connections. And for calibrating Tel-Tru's thermometers, the NIST traceable Check-Temp calibrators offer accuracy to +/- 0.2°F.

For pressure applications Tel-Tru offers a wide variety of gauges for almost any application. With pressure ranges up to 20,000PSI these gauges are available in plastic, steel, and stainless steel both filled and non-filled. High accuracy applications are no problem with the 42S series, offering +/- 0.25% full-scale accuracy. A full line of accessories is available including diaphragm seal protectors, pressure snubbers, mini needle valves, steam gauge siphons, and gauge cocks.
