This sale is for a new old stock (2016) SP-Lite Kipp & Zonen pyranometer. Offered by Adcon Telemetry who appears to have put the kit together in Germany. The item number on the box is A200733020. Silicium Pyranometer SP-LITE incl. amplifier. This item was designed for routine measurement of solar radiation under all weather conditions. Made for measuring available energy for use in solar energy applications, plant growth, thermal convection and evapotranspiration calculation. I obtained this item from an estate. The previous owner purchased it new but had not yet used it. He had a business that used remote monitoring and management of irrigation on large ranches and farms. The item in this sale looks in excellent unused condition. The purchaser gets what is pictured in above photos.
