Solar Light’s Model PMA2106 Digital Non-Weighted UVB Sensor provides an accurate measurement of UVB ultraviolet radiation from sunlight or artificial light sources. The sensor has angular response very close to an ideal cosine function (Lambertian response) making it suitable for measurements of diffuse radiation or radiation generated by extended sources. When used with Solar Light’s PMA-Series Radiometers, the measured irradiance can be displayed in mW/cm2 or W/m2. High dynamic range allows measurements of very weak signals down to 0.001 mW/cm2 and very strong irradiances up to 20 mW/cm2. The angular response of the PMA2106 sensor is cosine corrected, and suitable for measurements of diffuse radiation or radiation from extended sources. Several packages are available for different types of environments, including standard, low profile, weatherproof, waterproof, and high volume applications.
