With the improvement of people's living standards and health concerns, oxygen concentrators have become an essential household product for relieving illness or health care. Oxygen concentrators can supply oxygen to improve the physiological and biochemical internal environment of the human body, and promote a virtuous cycle of metabolic processes, so as to achieve
The basic function of the spectrum analyzer is spectrum analysis, which is the frequency and power test of the signal. This article lists several common signal types and application scenarios, summarizes the setting rules of the spectrum analyzer, and simplifies the steps while ensuring the best accuracy. The main function of the
The acoustic imager is a portable real-time acoustic imager that can visualize the sound source in the form of a color contour map, forming an effect similar to that of a thermal imager on the temperature of an object. This design uses an optimized spiral array, which is optimized for the detection of high
In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator
Handheld spectrometers typically come standard with two swappable lithium-ion batteries. Before using the battery, to check the battery status of the handheld spectrometer, press the white button on the battery. The length displayed by the green light indicates the percentage of remaining power, with 4 scales of 25%, 50%, 75% and 100%.
Ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument, which can quickly, conveniently, non-destructively and accurately detect, locate, evaluate and diagnose various defects (cracks, looseness, pores, inclusions, etc.) inside the workpiece. It can be used in both laboratory and engineering site. Widely used in boilers, pressure vessels, aerospace, aviation, electric power, petroleum,
Many medical equipment lithium-ion batteries, medical equipment lithium-ion batteries, instrument batteries, equipment batteries, medical batteries and medical equipment batteries are basically the same, and you must not be opportunistic when making these medical batteries, it may affect the use of medical equipment, equipment When the battery function is severe, the battery of the
SMBus (System Management Bus) was proposed by Intel in 1995. Its original purpose was to define a communication link between smart batteries, rechargeable batteries and microcontrollers that communicate with other systems. It is a cheap and powerful A bus (consisting of two wires) for low-rate data exchange between a master and a smart battery
Smart battery, also known as Smart Battery System (SBS), is a branch and an important part of modern power technology. Smart batteries utilize internal electronics to measure, calculate, and store battery data, making power usage and management more predictable. A basic SBS system consists of the following parts: System Management Bus (SMBus), Smart Battery
The International Electrotechnical Commission (IEC) is a standard-setting organization that includes all national electrotechnical commissions. The purpose of the IEC is to promote international cooperation on all standards in the field of electronics and electricians. To this end, IEC publishes international standards, technical specifications, technical reports, publicly available specifications, and guidance. These preparations were entrusted to the
