The 501 UVA radiometer is a meteorological grade instrument for outdoor and underwater (up to 5 meters) UVA radiation measurement. It has been widely used in weather stations and meteorological observatories around the world.
World-leading production experience, as well as NIST standard calibration, make each instrument highly repeatable and comparable.
All radiometers have an analog voltage output proportional to the measured UV radiation value. In addition, compared to other radiometers, all 501 radiometers have an internal temperature control system to ensure their high accuracy.
The analog output type can output a voltage proportional to the measured UV radiation. In addition, the 501 radiometer has internal temperature control, which has higher accuracy than other instruments.
All products are factory calibrated to NIST traceable standards.

application:
Used to measure 320nm-400nm UV radiation from sunlight and artificial light sources.
Studies of ozone or other biological effects on vegetation, marine life, climate where long-term in situ measurements are required.
Correction for radiation measurement errors caused by irradiance changes during the scanning process.
UV radiation measurement is used by the media or research institutions to release information about the impact of ultraviolet radiation to the public.
