The Fluke 52 Digital Thermometer is a dual-input instrument for precise temperature measurement across laboratory, quality assurance, process calibration, food safety, and HVAC/R applications. It simultaneously measures and displays temperatures from two independent sources with laboratory-grade accuracy and fast response times in a compact, rugged package.
Technical Specifications
Thermocouple Types: J, K, T, and E-type supported.
