The Dwyer 472A-1 Dual Input Thermocouple Thermometer precisely measures up to two temperature inputs simultaneously. Its large triple LCD display can show both temperature inputs or one input and the differential temperature (T1-T2). Any J, K, or T type thermocouple with a mini-jack connector can be used as an input, providing flexibility for various applications.

Temperature ranges cover J-type (-328 to 1400°F), K-type (-328 to 2498°F), and T-type (-328 to 734°F), with accuracy of ±0.1% of reading plus 1.4°F (0.7°C). Resolution is 0.1°C up to 500°C, ensuring precise readings. For viewing in poorly lit environments, the built-in backlight brightens the display for easy reading.

A hold button allows the user to freeze temperature data displayed, while minimum and maximum readings can be recorded over a set time period. The 472A-1 is CE approved and operates on a standard 9V alkaline battery, which is user replaceable. Its dual-input capability and differential temperature display make it ideal for HVAC, industrial maintenance, and laboratory applications where comparing two temperatures or monitoring temperature differences is essential.
