The 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 back light brightens the display.
A hold button allows the user to freeze temperature data displayed. Minimum and
maximum readings can be recorded over a set time period. Model 472A-1 includes a
hard carrying case, battery, and one K type thermocouple.
