The B&K Precision BE 9 AC power adapter for digital thermometers is rated for 9VDC/200mA output, and UL listed. This power adapter is an accessory for dual input digital thermometers. It is rated for 9VDC and 200mA (milliamperes) output. It is listed to applicable UL Standards and requirements by UL (Underwriters Laboratories). Its barrel jack measures 11mm long, 3mm in diameter, with a 1mm internal diameter.
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 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.
