Welch Allyn 24020 Otoscope Electric Otoscope Bulb 03400 2.5V compatible new
With the rapid development of technology, the use of otoscopes has become an essential tool for medical personnel to examine patients' ears. Because it is compact, convenient, applicable, and easy to use, it has won the favor of many medical staff. The otoscope bulb is generally equipped with a 2.5V DC voltage, which is used for 360 degree strong light balance to ensure that medical personnel can shine into the patient's ear for comprehensive examination and provide accurate and precise evaluation.
The service life of otoscope bulbs is related to multiple factors:
For example, the type of light bulb selected has a long working life;
2. It is also affected by the usage environment, such as temperature and humidity: in high temperature and high humidity environments, the lifespan of light bulbs will be greatly shortened. If the air quality is high and there is a lot of dust in the environment, the dust will adhere to the filament, affecting the luminous effect and lifespan of the light bulb.
Manufacturing materials and processes are important factors determining the lifespan of light bulbs. Poor quality materials or inadequate craftsmanship can shorten the lifespan.
Stability of voltage and current
Voltage and current fluctuations can accelerate the aging and burning of the filament. Stable voltage and current help extend the lifespan of light bulbs.
Use the resistance range of the multimeter to measure the resistance of the filament. The resistance of the filaments of different specifications of bulbs has a certain normal range. For example, if the common otoscope bulb is 6V, 0.5A, according to Ohm's law, its resistance is about 12 ohms. If the measured value is too different from the theoretical value, it may indicate that there is a problem with the filament.
