About Thomas 4040 Traceable Thermometer/Clock, +/- 1

The Thomas Thermometer/Clock auis a digital thermometer and humidity meter with clock used for monitoring the temperature and humidity in hoods, store rooms, clean rooms, incubators, drying chambers, and environmental cabinets. The thermometer measures temperature 0 to 50 degrees C (32 to 122 degrees F), with an accuracy of + or -1 degree C. The thermometer has internal sensors for ease of use. The thermometer memory stores minimum/maximum values. The thermometer, hygrometer, and clock are individually traceable to National Institute of Standards and Technology standards, indicating that it is calibrated to International Organization for Standardization (ISO) 17025 levels. The Thomas Thermometer/Clock is used in food storage, scientific laboratories, and other industries that require temperature monitoring. Specifications Power source (1) AAA battery Temperature range 0 to 50 degrees C (22 to 122 degrees F) Accuracy + or - 1 degree C Resolution 0.1 degree C/0.1 degree F Standard met International Organization for Standardization (ISO) 17025 Weight 2.5oz. Dimensions (H x W x D) 4.25 x 2.25 x 0.55 inches H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back. 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.
