Thomas 4048 ABS Plastic Memory Thermometer -58 to 158°F, -50 to 70°C

The Thomas Memory Monitor thermometer is a digital thermometer for monitoring the temperature in liquids, gases, water baths, freezers, and refrigerators. The thermometer measures temperatures from -50 to 70 degrees Celsius (-58 to 158 degrees Fahrenheit) with an accuracy of + or -1 degrees Celsius. The 0.75-inch probe includes a small 10-foot cable that seals in the refrigerator door without leaving a gap. The thermometer's memory stores minimum/maximum readings and has a temperature alarm that can be programmed to sound an audible signal if the temperature exceeds the maximum or minimum reading. Even if the temperature returns to the set range, the alarm will continue until it is turned off. This thermometer can be traced back to the National Institute of Standards and Technology and indicates that it is calibrated in accordance with the International Organization for Standardization (ISO) 17025. Thomas Memory Monitor thermometers are used in food storage, scientific laboratories, and other locations where temperature monitoring is required.

Temperature range -50 to 70°C (-58 to 158°F) Accuracy + or -1°C Accuracy 0.1°C / 0.1°F Probe length 0.75" probe diameter 0.31" cable length 10 feet ISO standard measurements 17025 Weight: 4 oz Dimensions (L x W x D) 4.25 x 2.75 x 0.75 inches

H is the height, the vertical distance from the lowest point to the highest point; W is the width and the horizontal distance from left to right; D is the depth, the horizontal distance from front to back.

A digital thermometer is an instrument used to electronically measure the temperature of air, liquid, or surfaces. You can measure temperatures in Celsius, Fahrenheit, or both. Most digital thermometers use thermistors, which are small electronic resistors. The thermistor is made of metal that conducts electricity in a specific area and becomes more conductive as the temperature increases. The microcontroller of this thermometer measures the conductivity and converts it into a temperature that is displayed on the LCD screen. Digital thermometers are used in a variety of applications including laboratory environments, food service, warehousing, doctor's offices, and hospitals.
