H-B Frio-Temp B61000-0000 Calibrated Electronic Verification Thermometer for Freezers, Refrigerators, Incubators and Ovens; -50/200C (-58/392F)

The H-B Instrument Frio-Temp Ace verification thermometer is used for verifying temperatures in freezers, refrigerators, incubators, and ovens in laboratories and food service systems. The thermometer measures temperature from -50 to 200 degrees C (-58 to 392 degrees F). The measurement accuracy is + or - 1 degree C from -20 to -50 degrees C and from 70 to 120 degrees C, and + or - 2 degrees C from -20 to 70 and from 120 to 200 degrees C. The 23mL glass bottle probe is attached to the unit by a 1.5m/4.9 ft. stainless steel cable. The unit has a minimum/maximum temperature memory for monitoring consistency of measurements. This thermometer is traceable to National Institute of Standards and Technology, indicating that it is calibrated to International Organization for Standardization (ISO) 17025 levels. The Frio-Temp Ace thermometer is used by scientists and food-service workers.

H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right.

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.
