Non Contact Thermometers For Humans (Top 5 Updated For 2020):
Understanding the difference between contact and non-contact temperature measurements is vital to addressing health, safety and quality issues in a wide range of industries.
Use of thermometers to measure temperature has been around for centuries and it is the second most frequently measured physical quantity after time. Various fields, including civil, mechanical, medical, manufacturing, quality control, and maintenance heavily depend on accurate temperature measurements.
They provide important information such as the condition of a machine, monitor the performance of a refrigerator or air conditioner, and help to determine if icing conditions exist in aircraft and agriculture.
Accurate temperature monitoring ensures that processes are operating consistently under optimum conditions resulting in improved product quality, increased safety, increased productivity, and reduced downtime. (source)
Type of thermometers
Thermometers are mainly classified into two major categories: contact and non-contact. In contact thermometers, contact sensors measure their own temperature.

Contact thermometers measure temperature using the heat transfer phenomenon known as “conduction.” They require physical contact with the measured object to bring the sensor body to the object’s temperature. While in non-contact measurements, an infrared sensor is used to measure the temperature of an object by reading the level of infrared emissions.
How Accurate Are Non Contact Thermometers For Humans?
Non contact infrared thermometers for humans are extremely accurate when being used correctly. Not all materials give off thermal radiation in the same way, and a material’s ability to give off this type of energy is known as its emissivity. Emissivity is measured on a scale from 0.00 – 1.00.
When accounting for emissivity and being aware of the nearby object that might interfere with a temperature reading, you can rely on the accuracy of a non-contact thermometer’s temperature reading. Thermometers that feature adjustable emissivity rather than fixed emissivity, are the most accurate and dependable option.

This feature allows the user to adjust the emissivity to account for whatever type of material they are trying to measure the temperature of. You will be able to use an adjustable thermometer on just about any surface material and know that your reading is precise.
How Do Non-Contact Thermometers For Humans Work?
Non-contact thermometers for humans contain a small lens that emits an infrared beam that bounces off the object and back to a detector that absorbs any radiation. This radiation is turned into heat and then into electricity. The thermometer can then convert this electricity into an accurate temperature reading.

The way non-contact thermometers work may sound complex but they basically detect a difference between the unit and the object that’s targeted. The way the electronics work allows the thermometers to give quick and accurate reading.
Some people may be daunted by using new technology when they’re accustomed to using glass thermometers or probes. Below is a link to a short video that shows you how to use a non-contact thermometer:
