Digi-Tru Digital Thermometers for Industrial/Sanitary Applications


Rugged yet affordable temperature instruments, the Digi-Tru Thermometer Series is designed for precise temperature monitoring in demanding industrial process applications.


Thermometers are fitted with a digital sensor that provides quick readings on a high-visibility LCD display, and an impressive accuracy of ±0.4°F (max) from -67 to 302°F (-55 to 150°C). These units feature a compact 3-in. (77 mm) round heavy-duty stainless steel case, and are available in back, bottom or adjustable angle configurations with industrial process or Tri-Clamp 3-A sanitary flange connections.


Each thermometer is calibrated and tested with instrumentation that is fully NIST traceable. A Certificate of Calibration is available for a nominal fee. Digi-Tru models meet FDA Rule 21 CFR 113.40 requirements for temperature indicators used in retorts and the requirements of the Pasteurized Milk Ordinance for dairy applications. Digital panels are available in standard white, as well as red or blue. Custom colors/imprints are available upon request.


All units are backed by a 2-year warranty from the date of shipment.
