Advantages of UV analyzer:

This instrument is widely used for analysis and testing in the departments of biology, chemistry, medicine, pharmacy, food and forensic identification. It can emit long-wave ultraviolet, short-wave ultraviolet and visible light at the same time. The biggest feature of the dark box ultraviolet analyzer is the fully enclosed design, which can be opened and used at any time, and has low power consumption. It is especially suitable for spot and detection of thin layer analysis and paper layer analysis.

Features of UV analyzer:

1. It is made of fully enclosed environmentally-friendly molecular strength ABS material, and the injection mold is formed at one time, which is firm and beautiful.

2. Set three switch keys to control 254nm, 365nm and visible light respectively.

3. The machine has the characteristics of low power consumption, low heat, and can be used continuously for a long time.

4. Low power consumption, low heat generation, and can be used for a long time.

5. The overall structure is simple, light and handy, the parts are universal, and it is easy to use and maintain.

FAQ:

Precautions for operating the UV analyzer:

In order to avoid electric shock, the input power cord of the UV analyzer must be grounded.

Before connecting the UV analyzer to the AC power supply, make sure that the voltage is consistent with the voltage required by the UV analyzer (a deviation of ±10% is allowed), and ensure that the rated load of the power socket is not less than the requirements of the UV analyzer.

The UV analyzer usually uses the supplied power cord.

The UV analyzer should be placed in a cool, ventilated, dry, and dust-proof location.

2. How to distinguish between ultraviolet rays?

Short-wave ultraviolet: referred to as UVC. It is ultraviolet light with a wavelength of 200-280nm.

Ultraviolet medium wave: referred to as UVB. It is ultraviolet light with a wavelength of 280-320nm.

Long-wave ultraviolet: referred to as UVA. It is ultraviolet light with a wavelength of 320-400nm.

3. The harm of UV analyzer:

The wavelength of the laboratory ultraviolet analyzer is 254nm short-wave ultraviolet and 365nm long-wave ultraviolet.

Short-wave ultraviolet light has a very small physiological effect on human skin.

Ultraviolet rays in the medium wave have certain physiological effects on human skin. Long-term exposure of such ultraviolet rays to the skin will cause erythema, inflammation, and skin aging. In severe cases, it can cause skin cancer. Medium-wave ultraviolet is also called the sunburn (red) section of ultraviolet rays, which is the ultraviolet band that should be prevented.　　

The penetration of long-wave ultraviolet rays on clothing and human skin is much stronger than that of medium-wave ultraviolet rays. It can reach deep in the dermis and can act on the melanin in the epidermis, causing skin melanin deposition, darkening the skin, and protecting against ultraviolet rays. Protect the skin. Therefore, the long-wave ultraviolet is also called the "tanning section." Although long-wave ultraviolet light does not cause acute skin inflammation, it has a slow effect on the skin and can accumulate for a long time. It is one of the causes of skin aging and serious damage. To

Therefore, the UV lamps we are exposed to are short-wave and long-wave, which are not very harmful, but they can hurt the skin.

Friendly reminder: Remember to turn off the UV lamp after completing the experiment. If it is not turned off for a long time, it may cause safety hazards.
