Digital Thermometers
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
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.
