1. The temperature gun displays E2
The heating rod displays the set target temperature instead of the current temperature.
2. What material is the backlight of the temperature gun made of
1. a. Optical grade material Polycarbonate (PC for short) polycarbonate: the temperature cannot exceed 80° (heat deformation temperature 92 degrees), commonly known as: acrylic). Plastic materials. Optical grade PMMA (polymethyl methacrylate; light transmittance Slightly lower (the penetration rate is about 89% when the thickness is 3mm)
2. b; The transmittance is high (the penetration rate is about 93% when the thickness is 3mm). ; Disadvantages, extrusion completed), advantages: high production efficiency (can be injection molded; disadvantages: temperature cannot exceed 110° (heat deformation temperature 135 degrees).
3. a. Advantages: high production efficiency (can be injected into the light guide plate. The commonly used material is optical grade PC
3. The temperature-sensing gun is accurate
1. It is not accurate enough. Use a temperature gun to measure the skin temperature of the wrist. This method of measuring body temperature is not accurate enough because the skin temperature of the wrist is affected by many external factors. It is affected by many factors, such as wearing clothes, wearing gloves, and the temperature of the surrounding environment. In addition, the temperature gun uses infrared rays to sense the body temperature, which is not as good as water.Silver thermometers measure accurate values. Therefore, using a body thermometer to measure wrist skin temperature is not accurate enough and cannot be used as medical evidence.
2. However, because the temperature gun is easy to use and detects quickly, it is suitable for census and screening of people with fever during the epidemic. There are three most medically accurate ways to measure human body temperature, including oral and sublingual temperature, axillary temperature, and rectal and anal temperature. The most commonly used way to detect human body temperature in medicine is to detect armpit temperature with a mercury thermometer.
4. How to cancel the sound of Braun ear thermometer
1. The design principle of the Braun ear thermometer is to use infrared rays to measure body temperature and calculate the body temperature value through temperature calculation. Therefore, it will have a measurement sound when it is used. However, this sound is to remind the user that the temperature measurement is in progress and also to facilitate the user to know that the measurement is completed. .
2. When using it, it is recommended to aim the thermometer into the ear for measurement, and measure quickly while keeping the child still.
3. In short, the Braun ear thermometer cannot completely cancel the sound, but it is very convenient and safe to use.
5. Braun ear thermometer anti-counterfeiting code query
Need to query The anti-counterfeiting code of the Braun ear thermometer can be checked through the following steps: 1. Find the packaging box or manual of the Braun ear thermometer, which will have the anti-counterfeiting code; 2. Open the official website of Braun and enter the \”Anti-Counterfeiting Query\” page; 3. Enter the anti-counterfeiting code found on this page, and the system will automatically query and verify the authenticity of the ear thermometer and give the corresponding query results; 4. If the displayed result is \”genuine\”, it means that the thermometer is The genuine Braun brand, otherwise it may be a fake or expired product.
Therefore, checking the anti-counterfeiting code is an important step that must be taken when purchasing a Braun ear thermometer.
