Tel-Tru’s Digital Thermometers are designed to deliver reliable accurate readings in the toughest industrial environments. All models are built to order using our wide range of configurations, delivering customers exactly what they need.

Dial Thermometers

Tel-Tru designs and manufactures industrial thermometers and other quality industrial temperature instruments to improve quality and operational performance.

RTD Sensors

Tel-Tru RTD thermometer probe assemblies and RTDs with integrated compact transmitter are designed for precision temperature measurement in demanding industrial or sanitary environments. All Tel-Tru RTD thermometers use high quality platinum RTD sensors, which are known for accuracy and reliability. Tel-Tru RTDs are configurable with numerous options to satisfy the needs of a broad range of applications.

Check-Set® Thermometer Calibrators

Check-Set Calibrator Data Logger for traceable digital record keeping.

Check-Set Calibrator for fast, easy, and accurate verification.

Remo-Tel®

The Remo-Tel Industrial Temperature Monitoring System automates temperature data logging and provides a 24/7 online monitoring dashboard for industrial and commercial operations to help mitigate risk for product loss and system failure and improve productivity. The Remo-Tel System is ideal for a wide variety of processes including Refrigeration, Molding, Brewing and other extremely time sensitive temperature monitoring applications.

Thermowells

Thermowells for sanitary applications as well as thermowells that can be treated and documented to NACE standards. Thermowells are recommended for pressure, corrosive fluid, or high velocity applications. Produced using highest quality material and machined from solid bar stock for standard or high velocity requirements in a large selection of materials and coatings. Designed and manufactured to assure perfect alignment with the thermometer stem.

Glass Industrial

Our glass industrial thermometers are versatile and adjust-angle, with a lens front and red liquid fill. They are NIST calibrated and guaranteed accurate to ± one scale division.

Selecting the Right Stem Length:

  • For accurate temperature readings, the length of the sensor must be fully immersed into the process equipment.
  • Tel-Tru bimetal thermometers have a groove that indicates the minimum depth that the thermometer stem needs to be inserted.
  • Stem lengths for thermometers with threaded connections are measured from the top of the thread to the tip of the stem. Non-threaded thermometers are measured from the back of the case to the tip of the stem.
  • Tel-Tru thermometer stems should never be modified. The bimetal coil assembly is in the lower 2″ of the stem, and if it is damaged, the thermometer is rendered unusable.
  • Tel-Tru can manufacture custom stem lengths from 2.5 to 120″ for bimetal thermometers, depending on the model.
  • We highly recommend the use of a thermowell in applications with flow or pressurization.
  • If you need help deciding which stem length is best for your industrial or sanitary application please contact us.

To ensure the longevity and accuracy of your Tel-Tru thermometer, please avoid placing the thermometer face inside or too close to a heat source, such as an oven, grill, or open flame. Excessive heat exposure may damage the thermometer’s internal components, leading to inaccurate readings or permanent failure.
