The Hanna Instruments HI98501 Checktemp C Thermometer is used for monitoring temperature in liquids, gases, and semisolids. The thermometer measures temperature from -50 to 150 degrees C, with an accuracy of + or -0.3 degrees C from -20 to 90 degrees C and + or - 0.5 degrees C outside this range. The 105mm/4.1" stainless steel stem probe has a penetration tip and is resistant to most laboratory chemicals. The thermometer has a Cal Check calibration function for increased accuracy. The thermometer includes a plastic cap for safety and protection. The HI98501 is used to measure temperature in restaurants, food storage facilities, and scientific laboratories.
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.
