Thomas Traceable Temperature/Humidity Pen, 32 to 122 degree F, 0 to 50 degree C

The Thomas Traceable Temperature/Humidity Pen measures air temperature and humidity in freezers, refrigerators, storage rooms, and laboratories. The thermometer measures temperature from 0 to 50 degrees C (32 to 122 degrees F), with an accuracy of + or - 1 degree C. The humidity gauge measures humidity from 20 to 95 percent relative humidity (RH), with an accuracy of + or - 3.5 percent. The thermometer has minimum/maximum temperature memory for monitoring the temperature consistency. 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 measure air temperature and humidity in restaurants, laboratories, and offices.

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.
