SS-110: Field Spectroradiometer-340 to 820 nm


Product Description

The SS-110 measures a wavelength range of 340 to 820 nm. The spectroradiometer is an easy-to-use, cost-effective, versatile spectral measurement system that can be interfaced to a computer or datalogger. 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).

The SS-110 package includes:

  1. Spectroradiometer unit and cosine corrected detector mounted in the housing

  2. 180° FOV head and black cap

  3. AL-200 bubble-level

  4. USB cable for computer interface

  5. Pigtail lead cable for datalogger interface

  6. 2GB USB drive with Spectrovision software and required drivers
