The Thomas Workstation Traceable Radio-Signal Remote Humidity Meter/Thermometer measures air temperature and humidity in ducts, laboratories, storage rooms, and outside. The thermometer measures temperature from -20 to 60 degrees C (-4 to 140 degrees F), with an accuracy of + or - 1 degree C. The humidity meter measures humidity from 25 to 90% relative humidity (RH), with an accuracy of + or - 2% RH. Remote sensor modules transmit measurements on a 433Hz signal up to 100 feet to the base module. Up to three remote sensors may be used with a single base station. Unit comes with one remote sensor. The LCD display has 1.375" high digits that can be read up to 25 ft. away. The thermometer has minimum/maximum temperature and humidity memory and a programmable temperature and humidity alarm for 24-hour monitoring. 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 air temperature and humidity in heating ducts, storage rooms, and other places where temperature consistency is important.

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.
