TEL-TRU

TEL-TRU is a manufacturer of temperature measurement instruments and pressure gauge accessories, headquartered in Rochester, New York, USA. The company has been in operation since 1917, producing dial thermometers, digital thermometers, RTD sensors, and related components for industrial, commercial, and laboratory applications. TEL-TRU’s product line includes general-purpose dial pocket thermometers, back-mount fixed-angle thread-mount dial thermometers, clip-on vat and pan thermometers, digital thermometers with NPT thread connections, and temperature calibrator accessories such as the Check-Set® series. The brand also supplies pressure gauge snubbers, like filter-type snubbers in 303 stainless steel with NPT connections, designed to dampen pressure spikes in fluid systems. TEL-TRU instruments are built to meet various industry standards, including NSF ratings for food-service applications, and offer accuracy specifications of ±1% for dial models and ±0.5°F/0.3°C for digital models. Stem lengths range from 4 inches to 18 inches, dial diameters from 1 inch to 3 inches, and temperature spans from -40°F to 750°F (-40°C to 250°C). The company’s products are used in process control, HVAC, food processing, pharmaceutical manufacturing, and laboratory settings. 3G Electric stocks over 460 SKUs of TEL-TRU thermometers and accessories, covering dial, digital, and RTD types, as well as snubbers and calibrator peripherals. This inventory supports global procurement for plant engineers and maintenance managers who require reliable temperature sensing with documented accuracy and material specifications. 3G Electric provides logistics support for these items, enabling consistent supply for ongoing operations without reliance on local distributors.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang TEL-TRU dari 3G Electric.

What accuracy specifications are available for TEL-TRU dial thermometers?

TEL-TRU dial thermometers typically offer an accuracy of ±1% of the full-scale range. This applies to models such as the GT500R-1514 (0°F to 250°F) and the BC550R-0402 (-40°F to 160°F). The accuracy is specified across the entire temperature span, making these instruments suitable for general-purpose industrial monitoring where moderate precision is required.

Are TEL-TRU digital thermometers available with NPT thread connections?

Yes, TEL-TRU digital thermometers, such as the ND5BB09111-P22046, feature a 1/2-inch NPT thread type. These fixed-angle general-purpose digital thermometers provide an accuracy of ±0.5°F/0.3°C and are designed for direct installation into process piping or tanks. The NPT connection allows for secure, leak-resistant mounting in industrial systems.

What materials are used in TEL-TRU pressure gauge snubbers?

TEL-TRU pressure gauge snubbers, like the model 723SG, are constructed from 303 stainless steel. This material offers corrosion resistance and durability in air and water/oil applications. The snubber uses a filter-type design to dampen pressure fluctuations, protecting gauges from damage. Connection type is NPT, and the snubber has zero pistons.

Does TEL-TRU offer NSF-rated thermometers for food service?

Yes, TEL-TRU produces NSF-rated laboratory dial thermometers, such as the GT100R-12/16121253, which are designed for vat and pan clip-on applications. These thermometers have a temperature range of -40°F to 160°F with ±1% accuracy and a 12-inch stem length. The NSF rating indicates compliance with sanitation standards for food-contact surfaces.

What stem lengths are available for TEL-TRU general-purpose dial thermometers?

TEL-TRU general-purpose dial pocket thermometers are available with stem lengths ranging from 4 inches to 18 inches. For example, the BC550R-0402 has a 4-inch stem, while the LT330R-1809 has an 18-inch stem. This range allows selection based on immersion depth requirements in pipes, tanks, or ovens.

Can TEL-TRU thermometers be used for both Fahrenheit and Celsius readings?

Many TEL-TRU dial thermometers display both Fahrenheit and Celsius scales. For instance, the GT500R-1514 covers 0°F to 250°F and -20°C to 120°C, and the BC550R-0402 covers -40°F to 160°F and -40°C to 70°C. Digital models typically offer switchable units or display both scales depending on the configuration.
