The Thomas Traceable long stem digital thermometer is used for measuring the temperature of liquids in cuvettes, test tubes, flasks, and beakers. The thermometer measures temperature from -50 to 150 degrees C and -58 to 302 degrees F), with an accuracy of + or - 1 degree C. The stainless-steel stem of the thermometer is 8" long and has a diameter of 0.13". The handle of the thermometer is 3 inches long with a diameter of 0.5", with an LCD display with 0.4"-high digits for increased visibility. The thermometer is traceable to National Institute of Standards and Technology standards, indicating that it is calibrated to International Organization for Standardization (ISO) 17025 levels. The Thomas long stem thermometer is used in tissue culturing, chemical experiments, and other scientific functions.

Digital thermometers are instruments used to measure the temperature of air, liquids, or surfaces electronically. They may measure temperature in Celsius, Fahrenheit, or both. Most digital thermometers use thermistors, which are small electronic resistors. Thermistors are made out of metals that conduct electricity within a certain range and become more conductive the warmer they get. A microcontroller inside the thermometer measures this electrical conductivity and converts it to a temperature, which is displayed on an LCD. Digital thermometers are used in a wide range of applications, including in laboratory settings, food service and storage, and in doctors' offices and hospitals.
