The Thomas Traceable Kangaroo thermometer is a dual-range digital thermometer used for measuring temperature in test-tubes, beakers, and other laboratory equipment. The thermometer measures temperature from -50 to 300 degrees C (-58 to 572 degrees F), with an accuracy of + or - 1 degree C between -30 and 250 degrees C. The 7.5"stainless-steel probe has a diameter of 0.125" and is resistant to most chemicals. It is attached to the base by a 42" cable. The unit has a built-in compartment to hold the cable when not in use. The LCD display has 0.75"-high digits for increased visibility. A built-in stand is included for hands-free viewing. 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 temperature in scientific laboratories.
|Temperature range /TD>||-50 to 300 degrees C (-58 to 572 degrees F)|
|Accuracy between -30 and 250 C||+ or - 1 degree C|
|Accuracy below -30 and above 250 C||+ or - 2 degrees C|
|Resolution||0.1 degree C (from -19.9 to 199.9 degrees C), 1 degree outside this range|
|Standard met||International Organization for Standardization (ISO) 17025|
|Dimensions (H x W x D)||4.75 x 2.5 x 0.5 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.
