The ultraviolet radiometer is a professional instrument for testing the luminous intensity of ultraviolet rays, that is, the ratio of the luminous flux obtained on the surface of an object to the illuminated area. It is mainly used to measure the radiant energy power density of ultraviolet rays, that is, the radiant energy power per square centimeter. UV calibration radiometer can be applied to monitor the intensity of ultraviolet lamp radiation in hospitals, health and epidemic prevention departments, chemical industry, electronics, food processing factories, public places, etc.

A UV radiometer is a device used to measure the intensity of UV light in a particular wavelength range, typically in the range of 200-400nm. UV radiometers are commonly used in industries such as pharmaceuticals, food and beverage, and water treatment. They are important for ensuring that products and processes are exposed to the necessary levels of UV light for sterilization purposes.
The UV 254 nm radiometer is specifically designed to measure the intensity of UV light at a wavelength of 254nm. This wavelength is commonly used for disinfection purposes, such as in water treatment plants. The UV 297 nm radiometer, on the other hand, is designed to measure the intensity of UV light at a wavelength of 297nm, which is often used in testing for the presence of organic molecules in materials.
|●||The sensitive window of the probe should be kept clean, otherwise it will affect the performance. Before the test, it can be wiped with lens paper.||Precautions for Use|
|●||The number hold button should not be pressed for more than 15 seconds each time, otherwise it will affect the life of the LCD.|
|●||When checking the radiation intensity for sample testing, wait for the UV intensity to stabilize before starting the measurement. (Wait for the machine to run for 30 minutes in winter, and wait for the machine to run for 15 minutes in summer)|
|●||Ambient temperature, voltage and surrounding reflections all have an impact on the intensity of UV rays.|
|●||Avoid measuring under direct sunlight, otherwise it will affect the measurement accuracy. The UV calibration radiometer should be calibrated once a year.|
|●||If the user encounters a fault during use, please check the “Fault Checklist” carefully !|
|●||If the + – symbol appears on the left side of the display, the battery voltage is low, please replace the battery.|
|●||Do not open the probe by yourself, the internal fiber optic sensor is easily damaged, if you cause any loss, you will be responsible for the consequences.|
|●||Protective glasses do not prevent UV rays from damaging your eyes from the side.|
UV irradiance meters, also known as UV light meters, are devices used to measure the UV exposure of surfaces and objects. They are commonly used in industries such as automotive, cosmetics, and health and safety. UV irradiance meters are important for monitoring the levels of UV radiation in a given area and ensuring that workers or products are not exposed to excessive levels of UV light. UV radiometers and irradiance meters are important devices for measuring and monitoring the intensity of UV radiation in various industries. They ensure that products and processes are exposed to the necessary levels of UV light for proper function and safety.
