Recently, I am writing a consulting articles. Considering the recent popularity of infrared thermometer, I would like to write an article on infrared thermometer testing consultation for readers’ reference.
The infrared thermometer consists of an infrared sensor, a Bluetooth module, a circuit component, an operation key, a plastic shell and a probe protection cover (if any). The working principle of the infrared thermometer is to compare the reflected infrared radiation on the skin surface with the spectral temperature correspondence table to obtain the accurate temperature value. Therefore, infrared thermometer can measure ear temperature, forehead temperature and dual-function mode, which is suitable for measurement in different situations. It is convenient, simple and fast, takes only a few seconds, and is quite accurate. During the outbreak of COVID-19, many countries and regions adopted isolation measures, and measuring body temperature was the first step to detect whether the virus was infected, so the sales of infrared thermometers soared.
The sensitivity and accuracy of measurement and display is the key to the performance of thermometers. Therefore, as an import purchaser, it is very important to know about the relevant tests of infrared thermometers before shipment. This paper discusses the appearance and function test of infrared thermometer from three aspects: structural composition, performance requirements and test methods. However, due to the limitation of the length of the article, some specific test standards cannot be listed one by one, and the test price and the time required for the test also vary according to the test items. if you need it, you are welcome to know about our inferior instrument testing consultation service and laboratory testing service. Inferred Thermometer Testing Consultation can save time and cost for purchasers, because we have many years of experience and are willing to share all the information we know with you.
1.Normal working conditions
A) ambient temperature: 16℃-40℃ (60.8 ℉-104 ℉);
B) relative humidity: ≤ 85%;
C) atmospheric pressure: 700 HPA-1060 HPA;
D) internal DC power supply d.c.3v has relative errors of+5% and-10%.
2.Appearance and structure
A) thermometer products shall have correct appearance, bright and clean surface, free from sharp edges, burrs, damages and deformation.
B) the characters and marks on the thermometer control panel shall be accurate, clear and firm.
C) the handwriting displayed on the display screen shall be free of random codes, wrong codes and missing strokes.
D) the top of the thermometer detector should be smooth and the edge should be free of burrs.
E) thermometer control mechanism should be flexible and reliable, fasteners without looseness.
8.Low voltage prompt function
For thermometers powered by internal DC source, when the voltage is lower than 2.4V 0 0.4V, the thermometer shall provide recognizable indication or stop displaying temperature readings.
9.Normal working condition
Place the infrared thermometer probe in the ear cavity or in front of the forehead, and press the scan measurement key to display the body temperature normally.
Thermometers shall have an automatic self-test program, and relevant information such as how to operate the self-test program shall be provided in relevant materials. Normal operation should be shown through correct display.
11.Automatic shutdown function
Thermometers with internal DC power supply shall have automatic shutdown function.
12.Bluetooth function: The infrared thermometer shall be able to connect with the designated equipment via Bluetooth and transmit the infrared thermometer data to the designated equipment.
13.Serial port function: infrared thermometer should be able to connect with designated equipment through USB data line and transmit infrared thermometer data to designated equipment.
14.Cleaning, disinfection and sterilization: If thermometers can be cleaned, disinfected and sterilized, instructions on these procedures should be provided.
The thermometer product description shall include the following contents:
The experimental methods partially explain the specific experimental methods and reference standards of the above tests. They are rather difficult and obscure, so they are not repeated here. If you want to know, we can provide the Inferred Thermometer Testing Consulting service. Our infrared thermometer testing consultation service
mainly includes testing price consultation, testing project consultation, importing national standards consultation, testing time consultation, etc. The essence of the Inferred Thermometer Testing Consultation Service is to ensure the quality of goods, while Supplier Quality Audit is to better ensure the quality of the factory, such as the factory scale management level, bank credit status.
At this distance, the central point I want to convey is that importers need to control all aspects in order to ensure the quality of goods, because profit-seeking and laziness are the eternal defects of human beings…….
