MS-11S UVB Radiometer:

The MS-11S UVB Radiometer is a device used to measure ultraviolet (UV) radiation in the UVB range (280-315 nm). UVB radiation is a type of ultraviolet radiation that can have negative effects on human health, as well as on plants and animals. It is one of the three types of ultraviolet radiation, along with UVA and UVC.

The MS-11S UVB Radiometer is a portable and easy-to-use instrument that can be used in a variety of settings, including laboratories, field studies, and industrial applications. It is equipped with a silicon-photodiode detector that is sensitive to UVB radiation, as well as a built-in LCD display that allows users to view measurement results in real-time.

The device is designed to measure the intensity of UVB radiation in both direct sunlight and diffuse skylight, and it can be used to measure both the total and spectral UVB radiation. The total UVB radiation is the sum of all the UVB radiation that is present in a given location, while the spectral UVB radiation is a measure of the specific wavelengths of UVB radiation that are present.

The MS-11S UVB Radiometer is an ideal tool for a wide range of UVB research and monitoring applications, including studies of UVB radiation levels in different environments, such as forests, deserts, and coastal regions; measurements of UVB radiation levels at different altitudes; and investigations of the effects of UVB radiation on human health, plants, and animals.

Additionally, MS-11S UVB radiometer can be used for monitoring UVB light for phototherapy treatment for psoriasis and vitiligo, UVB radiation levels in the workplace, UVB exposure levels for outdoor workers, UVB exposure levels in indoor environments, UVB exposure levels for athletes and in UVB light sterilization.

The MS-11S UVB Radiometer is equipped with a USB port, which allows users to easily connect the device to a computer for data storage and analysis. The device also includes a software package that can be used to analyze and visualize the data collected by the radiometer, making it easy to obtain detailed and accurate information about UVB radiation levels in a given location.

Overall, MS-11S UVB Radiometer is a versatile and powerful tool that can help researchers, scientists, and other professionals to better understand the impact of UVB radiation on the environment, human health, and other areas of concern.

The MS-11S UVB with integrated transducers delivers precise temperature correction, exceptional stability, superior UV measurement range, and unbeatable response times.
