The Thomas Traceable Ultra Full-Scale Thermometer measures temperature in water baths, incubators, freezers, and other laboratory equipment. The thermometer measures temperature from -50 to 250 degrees C (-58 to 500 degrees F), with an accuracy of + or - 0.5 degrees C between -20 and 100 degrees C. Its 5.75" stainless-steel probe is resistant to most laboratory chemicals. The probe is attached to the base by a 10-foot cable. The LCD display has 3/8" high digits. The base has a magnetic back for mounting on a metal surface, a flip-open stand, and a spring fastener for clipping on any edge. 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. This Thomas thermometer is used to monitor temperature in liquids and semisolids in laboratories and industrial settings.

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.
