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.

During grape growing and harvesting, temperature affects the development and ripening of grapes, influencing crucial factors such as sugar content, acidity, and flavor profile. Tel-Tru’s temperature monitoring instruments help vineyard managers track temperature fluctuations, ensuring grapes are harvested at the perfect ripeness for the desired wine style.
Tel-Tru’s equipment allows winemakers to maintain precise temperatures during crushing and pressing, preventing oxidation and microbial growth, while preserving the delicate aromas and flavors present and purity of the juice
Tel-Tru’s temperature monitoring devices enable winemakers to monitor fermentation temperatures closely, ensuring optimal conditions for yeast metabolism and flavor development and aromas from the grape skins.
In the aging and storage phase, temperature stability is essential to ensure consistent maturation and prevent spoilage. Tel-Tru’s instruments help wineries maintain precise temperatures in tanks, barrels, and bottles, allowing wines to develop complexity and character without the risk of oxidation or microbial contamination.
During bottling and storage, temperature control maintains wine quality and stability. Tel-Tru’s temperature monitoring equipment ensures that wines are bottled and stored at the correct temperatures, preserving their freshness and preventing premature aging.
