Skye is pleased to announce a NEW addition to its range of popular
multi-channel light sensors designed for Remote Sensing applications.
- a NEW sensor from a Company with over 30 years experience in designing and manufacturing light sensors
- high quality and affordable
- research grade
- waterproof and rugged
- sensors individually calibrated, radiance and irradiance, and supplied with a calibration certificate
- calibration traceable to UK national standards at the National Physical Laboratory
- calibration in µmols or watts
- suitable for long-term outside installations
- lightweight
- standard NDVI/PRI wavelengths or user choice
- bespoke wavelengths available between 400 and 1050nm
- suitable for installations on masts, flux towers, aeroplanes, UAVs
- instantaneous synchronised readings from radiance and irradiance sensors when used with Skye meters and dataloggers
- systems available with GPRS communications for automatic upload to a website
