1. When using this product to measure temperature, consider the ratio between the distance (the length from the product to the measured object) and the size of the measurement area, referred to as the object distance ratio. When the distance between the product and the measured object increases, the measurement area will increase accordingly.

2. If you want to use boiled water to measure the quality of the product, please note that when measuring boiling liquids, do not allow smoke or water vapor to contact the temperature sensing area, and keep the measurement angle at 45 ~ 60 degrees.

Are infrared thermometers accurate?

Infrared thermometers have good accuracy when measuring most objects, but shiny, reflective surfaces can be a challenge. You should be especially wary when measuring the temperature of shiny metal objects, but even reflections off of glossy paint can affect accuracy

What do you use an infrared thermometer for?

Infrared thermometers are ideal for recording fryer oil temperature (350°F), giving you the ability to perfectly gauge when your batter-dipped chicken is ready to fry. Used properly, an infrared thermometer is the perfect tool for helping you shore up air leaks and address poorly insulated areas around the house.

Can you use an infrared thermometer for cooking?

Since infrared thermometers only measure surface temperatures, they are not very effective at gauging the doneness of foods. Only traditional probe thermometers can determine the internal temperature of solid foods

Can Infrared thermometers measure air temperature?

Laser IR Thermometers measure the surface temperature of an object by measuring the thermal energy emitted by the target. … To accurately measure the output temperature of an air heater you must measure air temperature and laser IR thermometers are incapable of doing so

How does an infrared thermometer work?

Infrared thermometers usually use a lens to focus infrared light from one object onto a detector called a thermopile. The thermopile absorbs the infrared radiation and turns it into heat. … The electricity is sent to a detector, which uses it to determine the temperature of whatever the thermometer is pointed at.

Do Infrared thermometers need to be calibrated?

Infrared thermometers cannot typically be calibrated at home, but they are known for their low drift. If the results of your ice bath test are within your unit’s manufacturer’s listed specification, you are good to go

Are infrared thermometers dangerous?

Infrared (IRthermometers are not harmful to kids as long as you don’t let your them play with it, they are not toys. IR thermometers do no emit radiation, only measuring it like a digital camera. Like all portable electronic equipment, they use batteries en these can be harmful when swallowed.

How does infrared detect temperature?

Infrared Temperature Sensors. Infrared temperature sensors sense electromagnetic waves in the 700 nm to 14,000 nm range. … Because the emitted infrared energy of any object is proportional to its temperature, the electrical signal provides an accurate reading of the temperature of the object that it is pointed at.
