A digital thermometer uses internal sensors that produce resistance, voltage or current change when there is a change in temperature. There are 3 main types which are RTD, thermistor or thermocouple.
A digital thermometer is a scientific instrument used to measure temperature. Digital thermometers use a probe to take the temperature and a numerical reading is clearly displayed on an LCD screen. They produce accurate readings and usually display the results in one decimal place. This makes them a popular choice as they tend to be more precise than liquid type thermometers.
Hand-Held thermometers are portable battery-operated devices with additional plugin probes. Probes can vary in type depending on the application. Popular probe types for handheld thermometers include insertion, surface or air probes.
