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.

Check-Set® Thermometer Calibrator

Fast. Easy. Accurate.
The Smarter Way to Calibrate Thermometers.

The NEW Check-Set® Thermometer Calibrator Data Logger and the Check-Set® Thermometer Calibrator are built for today’s food safety, industrial processing, and temperature-sensitive industries—where accuracy, compliance, and traceability are non-negotiable. Unlike the old-fashioned boiling water and ice bath method, Check-Set takes the guesswork out of calibration. It delivers lab-grade accuracy to ±0.2°F (0.1°C) – and records results to support FDA, FSMA, HACCP, and GFSI compliance.
