The PD300RM-8W LED and laser radiometer replaces traditional radiometers which are calibrated to a single wavelength (254nm, 365nm, etc.), offering calibration over a broad spectral range, which the user can access by entering any wavelength in the calibration range. The PD300RM is a general purpose circular geometry photodiode irradiance and dosage sensor with an 8mm aperture and a cosine corrected diffuser. Its spectral range is 350-850nm and its irradiance measuring range is 1μW/cm² - 8W/cm². The sensor comes with a 1.5 meter cable for connecting to StarBright & StarLite meters or Juno+ PC interface.
