Today, we’ll take this opportunity to introduce you to some key points about ozone concentration detectors. If you’re curious, hurry up and take a look!
Before using an ozone concentration detector, there’s quite a bit of basic information we need to understand—after all, the underlying principles involve many different areas of knowledge. For example, ozone concentration detectors operate on the principle of ultraviolet absorption: they use a stable UV light source to generate ultraviolet light. The detector employs optical filters to block out other wavelengths of UV light, allowing only light at a wavelength of 253.7 nm to pass through. After passing through the sample’s photoelectric sensor, the light then travels through an ozone absorption cell and reaches another photoelectric sensor for sampling. At this point, it’s essential to compare the electrical signal from the sample’s photoelectric sensor with that of the reference sensor, and then use a mathematical model to calculate the ozone concentration. Since we’re going to be using such a device, it’s important to know that Earth’s atmosphere has an ozone layer. Scientists have discovered that the ozone layer can absorb ultraviolet radiation. Research shows that ozone exhibits a high absorption coefficient specifically for ultraviolet light with a wavelength of 253.7 nm. Therefore, as ultraviolet light passes through ozone at this particular wavelength, its intensity diminishes—a phenomenon that conforms to the Lambert-Beer law.
This method has been adopted by countries such as the United States as the standard analytical method for ozone. The ozone concentration detector operates on the principle of ultraviolet absorption: it uses a stable ultraviolet light source to generate UV light, and then employs optical filters to eliminate ultraviolet light at other wavelengths, allowing only light with a wavelength of 253.7 nm to pass through. After passing through the sample’s photoelectric sensor, the light travels through an ozone absorption cell and finally reaches the sampling photoelectric sensor. By comparing the electrical signals from the sample photoelectric sensor and the reference photoelectric sensor, and applying a mathematical model, the ozone concentration can be determined. In addition, the ozone concentration detector consists primarily of a low-pressure UV lamp, an optical filter, an incident UV light reflector, an ozone absorption cell, a sample photoelectric sensor, a sampling photoelectric sensor, an output display, and various circuit components. Due to its numerous advantages, this ozone concentration detector is widely used in applications such as ozone-generation workshops (including ozone generators and ozone equipment), the chemical, petroleum, paper-making, textile, pharmaceutical, and fragrance industries, as well as in water treatment facilities and food and pharmaceutical sterilization workshops.
