What is a bimetallic stemmed thermometer and how does you use it?
What is a bimetallic stemmed thermometer? It’s a thermometer that can check temperatures from 0 degrees Fahrenheit to 220 degrees Fahrenheit. It’s useful for checking temperature during the flow of food. It measures temperature through its metal stem.
What temperature should a bimetallic stemmed thermometer?
0°F to 220°F
A common type of thermometer, bimetallic stemmed thermometers can check temperatures from 0°F to 220°F, making it a great tool to check products throughout the flow of food process, from receiving to periodic monitoring while serving in a hot or cold holding unit.
How accurate are bimetallic stemmed thermometers?
It’s the only thermometer that can be calibrated, has a dimple to mark the end of the sensing area, and needs accuracy within 2 degrees.
What is a stem thermometer used for?
A dial stem thermometer can easily be used in roasts, casseroles, and soups. It must be inserted sideways into thin foods like burgers, steaks, or chops. Use a thermometer to check the internal temperature of a food at, or near, the end of cooking time.
How do you treat a bimetallic stemmed thermometer?
Bimetallic Stemmed Thermometers: Calibrate on a regular basis and after using the thermometer with very hot or very cold foods, or after dropping or jarring it. In a clean styrofoam cup, make an ice water slush by filling the cup halfway with ice cubes and the rest with water.
Where do you place a bimetallic stemmed thermometer in food?
When measuring the temperature of food with a bi-metallic thermometer, it must be inserted into the product up to the dimple mark in the stem. You should insert the thermometer into the thickest part of the food and check in two locations to make sure the proper temperature has been reached.
What are the components of a bimetallic stemmed thermometer?
* Bi-metallic stemmed thermometers: It measures temperature through a metal stem with a sensor in the lower end. The sensing area is from the tip to a half-inch past the dimple. The temperature is read on the dial face.
What is the first steps for calibrating a bimetallic stemmed thermometer?
PUT THE THERMOMETER STEM OR PROBE INTO THE ICE WATER. Make sure the sensing area is under water and not touching the sides of the container. Wait 30 seconds or until the reading stays steady. ADJUST THE THERMOMETER SO IT READS 32°F (0°C).
What is the principle of bimetallic thermometer?
Bimetal thermometers work on the principle that different metals expand at different rates as they are heated. By using two strips of different metals in a thermometer, the movement of the strips correlates to temperature and can be indicated along a scale.
What is a safe temperature?
Normal body temperature varies by person, age, activity, and time of day. The average normal body temperature is generally accepted as 98.6°F (37°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.
What is the function of bimetallic thermometer?
The thermometer gives the less accurate result while measuring the low temperature. The bimetallic thermometer is used in household devices likes oven, air conditioner, and in industrial apparatus like refineries, hot wires, heater, tempering tanks etc. for measuring the temperature.
What does bimetallic mean?
Definition of bimetallic. 1 : relating to, based on, or using bimetallism. 2 : composed of two different metals —often used of devices having a part in which two metals that expand differently are bonded together.
What is the use of a bimetallic thermometer?
The bimetallic thermometer is used in household devices likes oven, air conditioner, and in industrial apparatus like refineries, hot wires, heater, tempering tanks etc. for measuring the temperature.
What does a bimetal thermometer consist of?
The bimetal thermometer is made up of two metals moulded together to form a coil. As the temperature changes, the bimetallic coil contracts or expands, causing the pointer to move up or down the scale.
