What is the difference between a personal thermometer and an industrial thermometer?
human body thermometer
The human body thermometer is an instrument that measures the surface temperature of the human forehead, and then obtains the actual body temperature of the human body based on the relationship between the forehead temperature and the body temperature.
It is mainly used to detect human body temperature in public places such as entry and exit ports, airports, stations, docks, hospitals, agencies, factories, schools, hotels and office buildings to facilitate the screening of patients with fever symptoms to reduce infection and the spread of the epidemic.
Industrial thermometer
Industrial thermometers play an important role in product quality control and monitoring, equipment online fault diagnosis and safety protection, and energy conservation during the production process. In the past 20 years, non-contact infrared thermometers have developed rapidly in technology, their performance has been continuously improved, their functions have been continuously enhanced, their varieties have continued to increase, their scope of application has also continued to expand, and their market share has increased year by year. Compared with contact temperature measurement methods, infrared temperature measurement has the advantages of fast response time, non-contact, safe use and long service life.
What is the difference between a human body thermometer and an industrial thermometer?
Today we take a look at the two types of thermometers that everyone is most concerned about: industrial handheld thermometers and human body handheld thermometers. The two thermometers have the same principle, but they are used in different fields. Industrial thermometers use a wide emissivity range of 0.1-1, and can handle differentiated measurements of a variety of materials. The temperature ranges from tens of degrees below zero to thousands of degrees, and the accuracy error will be relatively large. Human body thermometers usually use an emissivity of 0.98. The measurable temperature range is relatively concentrated between 30-50°C. The accuracy error is generally between 0.1-0.5. A fever alarm is usually set.
We really need a thermometer to measure human body temperature in life. It is recommended to use human body temperature measurement first. It is simple, convenient and more accurate. If there is no human body to use, there happens to be an industrial thermometer. You can do this:
1. Set the emissivity of the thermometer to 0.98. If it cannot be set, just use the default 0.95. First, measure the temperature difference between yourself or someone whose body temperature is normal for three to no one to see.
2. When measuring the forehead, wipe away sweat, hats, scarves and other obstructions. If the temperature is found to be too high during the measurement, the person being measured can take a break or use the armpit clamping method of a mercury thermometer to measure.
3. Do not shine your glasses directly when using the thermometer.
