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.

Compliance with standards such as the Food Safety Modernization Act (FSMA) is mandatory. Tel-Tru provides indispensable temperature measurement instruments tailored for the unique demands of the food safety industry. Our commitment extends from seamless installation to meticulous calibration, verification, and validation, meeting FDA hygienic food safety and engineering design standards with precision.
The Hazard Analysis Critical Control Point (HACCP) framework requires precise measurements across critical control points (CCPs), including temperature. Tel-Tru’s instruments provide the accuracy and reliability necessary to meet HACCP’s standards. Proper calibration of temperature measurement instruments is imperative, and Tel-Tru offers the Check-Set Calibrators to streamline verification, ensuring compliance with HACCP mandates.
Tel-Tru’s commitment to food safety extends beyond industrial settings. NSF® approved Food Service Thermometers cater to the needs of food and beverage processing, food service, barbecue, cooking, OEM equipment, and retail. From meat and poultry testing to gourmet cooking and quality control, Tel-Tru’s thermometers uphold the highest standards of food safety and quality.
Understanding the distinction between safety and “doneness” is pivotal. While visual cues may help gauge the desired state of food, only a food thermometer can ensure safety. Adhering to recommended internal temperatures—verified with a food thermometer—mitigates the risk of foodborne illness.
Proper temperature management includes food storage. Cold foods must be maintained at 40°F or below, while hot foods should remain above 140°F to prevent bacterial proliferation. By using food thermometers at every stage of food handling, from preparation to serving, to storage, consumers can safeguard against potential health risks and uphold food safety standards.
Temperature measurement is essential in the food safety industry, supporting regulatory compliance, brand integrity, and consumer well-being. As the food industry continues to evolve, prioritizing temperature measurement remains crucial for safeguarding consumer health and trust. Tel-Tru’s precision instruments offer food safety professionals confidence and peace of mind.
