The Supco DDT2 dual-input K-type thermocouple digital differential thermometer with probes is for use in applications requiring a broad range of temperature measurements, including superheat measurements, food service applications, and heating, ventilation, and air-conditioning system maintenance. It measures temperature from -200 to 1370 degrees C (-328 to 2498 degrees F), with a best accuracy of + or - 0.3% of reading plus 1 degree C (2 degrees F). The K-type thermocouple sensor has a broader temperature measurement range than a thermistor sensor but provides lower accuracy. This dual-channel thermometer has two inputs for connecting K-type temperature probes (included), allowing the operator to measure the temperature of two samples at one time. The LCD screen can display the current temperature measurement for either input channel as well as the difference between the two channels. It can also display the highest or lowest temperature reading for a session, the difference between two successive measurements, and the average temperature recorded in a session. The operator can choose to display readings in degrees Fahrenheit or Celsius. The thermometer's internal memory can record up to eight sets of minimum, maximum, and average temperature data for future recall. The hold function keeps a measurement on the display so it can be recorded. An RS-232 serial port on the body of the thermometer allows measurement data to be transferred to a computer (data cable not included). The thermometer operates on one 9V battery (included), and the thermometer will automatically turn off after 30 minutes of non-use to conserve battery life. A low-battery indicator alerts the operator when the batteries need to be replaced. Two K-type bead probes are included with the thermometer, and the thermometer will accept other styles of K-type thermocouple probes. A vinyl carrying case is included to help protect the thermometer during transport and storage.

Digital thermocouple thermometers measure the temperature of air, liquids, or surfaces. They may measure temperature in Celsius, Fahrenheit, or both. Thermocouple thermometers are composed of two conductors of different metals, usually alloys of the same metal, which touch at the sensor end of the thermometer. The difference in conductivity between the two metal pieces produces a voltage flow between the sensor end and the open end of each conductor, which can be used to determine the temperature. Different alloys are used for different temperature ranges. Thermocouple thermometers are used in applications that require a large temperature range and do not require a high degree of accuracy. These thermometers are used in kilns, turbine exhaust systems, and furnaces.
