Dwyer Instruments” Model 472A-1 dual-input thermocouple thermometer precisely measures up to two temperature measurements simultaneously. The large LCD display shows both temperature inputs or one temperature input and the differential temperature. Any J, K or T type thermocouple with a mini-jack connector can be used as an input. For viewing in poorly lit environments, the built-in backlight brightens the display. A hold button allows the user to freeze temperature data displayed and minimum and maximum readings can be recorded over a set time period. The thermometer includes a hard carrying case, battery, and one K Type thermocouple.
