  • Product Name: UV to Visible Range Lab Spectroradiometer
  • Item No.:PS-200
  • Manufacturers:Apogee
  • Country of Origin:USA

The PS-200 measures a wavelength range of 300 to 850 nm. The spectroradiometer comes in a complete package ready to connect to your computer and begin making measurements. Typical applications include measurement of spectral output (energy flux density, photon flux density, or illuminance) of different radiation sources (often for plant or human lighting), and reflectance and transmittance measurements of natural and synthetic surfaces and materials (often plant leaves and canopies).
