Q1: What is the difference between an infrared thermal imager and an infrared thermometer?

De Tu:Infrared thermometer measures the average temperature of a circular area with the measured point as the radius. This type of product needs to consider the distance coefficient ratio of the product, so the measurement distance is short and the accuracy is related to the measurement distance, making it impossible to measure the temperature surface of the measured object over a large area. Commonly used for rapid detection of individual body temperature, the well-known thermometer is an infrared thermometer.

The working principle of an infrared thermal imager is that "any object above zero emits infrared radiation". Therefore, the detector of an infrared thermal imager can passively receive the infrared radiation of the object being measured, convert it into temperature values, and visually display the temperature distribution of the object being measured. itIt has the characteristics of non-contact measurement, temperature visualization, and large-area measurement, and is not harmful to the human body. This also means that using infrared thermal imagers for temperature screening can achieve greater safety, efficiency, and minimize missed detections.

Q2: How to avoid false positives during temperature screening?

De Tu:In daily life, we often have the experience that sometimes our body temperature is over 37 ° C or only below 36 ° C, but we feel quite healthy and there is no discomfort. So, what criteria does the thermal imager use to determine if there is a temperature difference during temperature screening? How can we avoid false positives? In fact, the normal body temperature of a person does fluctuate. When stimulated by the temperature of the internal and external environment, the body automatically adjusts its temperature to achieve a new body heat balance and adapt to the environment. The key to reducing false positives and false negatives caused by normal temperature regulation lies not in the measured temperature, but in identifying abnormal alarm temperatures. This alarm temperature should be a floating value.

Most thermal imaging devices currently available on the market require prior input of a temperature alarm value (i.e. average human body temperature). If the temperature exceeds this alarm value, the thermal imaging camera will sound an alarm. Entering a fixed value may cause errors and false positives.The epidemic prevention detection function of the Detu thermal imager automatically adjusts the temperature alarm value through a special algorithm, identifies "potential patients" with abnormal body temperature exceeding the crowd, and immediately alarms.

Q3: Is there an alarm prompt when the thermal imager detects abnormal body temperature?

De Tu:The Detu testo 885/890 infrared thermal imager has an alarm function, which can set dual sound/color alarm prompts to avoid omissions caused by personnel fatigue or unclear prompts.

Q4: What is the difference between a thermal imager with epidemic prevention detection function and other thermal imagers?

De Tu:The body surface temperature varies with different body parts, and the accuracy of temperature screening is also affected by which part of the body is measured. Generally speaking, the temperature at the eye socket is close to the core temperature of the human body, which is particularly suitable for representing the true body temperature of the human body. So, in addition to the special algorithm for automatically adjusting the alarm temperature value mentioned above,The thermal imager with epidemic prevention detection function has a facial recognition algorithm that automatically measures the temperature at the eye socket of the human body, and detects each subject in the crowd one by one, guiding users to quickly complete accurate temperature screening.Detu provides a thermal imaging camera for epidemic prevention testing and recommends that you remove your glasses when quickly detecting eye socket temperature, as glasses can block infrared radiation.

Q5: Why choose a thermal imager with screen mirroring function?

De Tu:The projection function of the thermal imager can output the images generated on the screen of the thermal imager to other display devices,By utilizing the non-contact measurement features of projection screens and thermal imagers, it is possible to ensure a safe distance between the testing personnel and the subject being tested, and prevent cross interference.The Detu testo 885/890 thermal imager has a projection function and uses an HDMI cable. It is suitable for most display devices and does not require any adapters.

Q6: How to choose portable, fixed, or semi fixed thermal imagers?

De Tu:Portable refers to direct handheld operation, suitable for inspection; Fixed type refers to the need to connect to a computer to display measurement images and control operations, suitable for long-term fixed-point detection; Semi fixed refers to the use of the Detu thermal imager even when there is insufficient or damaged online equipment, which is easy to fix and does not require special installation.

Q7: Do you have the DeTu infrared thermal imager in stock?

De Tu:The testo 882 infrared thermal imager is available in stock. Due to the special period of the epidemic, customers can confirm their orders through email first, and then complete the payment process such as the contract. The testo 885/890 thermal imaging camera with epidemic prevention detection function has been transferred from Germany and will soon be available for ordering.
