how does a digital thermometer works without mercury

Answer 1 of 7. Mercury thermometers are based upon the practical phenomena that mercury expands with temperature.

Temperature Digital And Glass Thermometers

Digital thermometers contain a device called a thermoresistor.

. Accuracy is typically 1 - 2 C. The thermoresistor has an electrical current running through it and the resistance or how freely the current can flow changes with temperature. Digital thermometers contain a device called.

How does a digital thermometer work without mercury. Resistance Temperature Detectors RTD or PT100 Thermistors. The thermoresistor has an electrical current running through it and the resistance or how freely the current can flow changes with temperature.

How does a digital thermometer work without mercury. 50 out of 5 stars Works great and very simple to use. A heavy silvery d-block element mercury is the only.

A small computer or other circuit measures the resistance and converts it to a. Most range from 05 to 1 C. It is not possible to measure the room temperature with a thermometer.

Whereas a food digital thermometer possesses a probe that is inserted in the thickest part of the food to get the most precise results. Thats the technique that mercury alcohol and gas-expansion thermometers use. Digital thermometers work by using heat sensors that determine body temperature.

They can be used to take temperature. 4 How does a digital thermometer work without mercury. How does a digital thermometer work without mercury.

Take a system that is tied to. How does a digital thermometer work without mercury. The food digital thermometers and body digital temperature are different.

Digital thermometers contain a device called a thermoresistor. Answer 1 of 6. Accuracy limits for non-mercury thermometers below 150 C are also compatible with mercury thermometers.

Digital thermometers contain a device called a thermoresistor. They work in similar ways but the one for the body is often inserted in your mouth to get the most accurate body temperature. Like liquid mercury the alcohol expands in volume as it gets warmer causing the liquid to move up the thin tube inside the glass thermometer.

Pick some physical parameter that varies with temperature and calibrate it by exposing it to known temperatures. Digital thermometers contain a device called a thermoresistor. Digital thermometers work by using heat sensors that determine body temperatureThey can be used to take temperature readings.
