URBARN Nano XL-500 Spectroradiometer
  • URBARN’s XL-500 is an ultra-compact Bluetooth Spectroradiometer based on disruptive digital-nano convergence technology. It provides feedback for growers by showing PPFD in real time—plus allows visualization of the spectral chart for quick reference.
  • The XL-500 is easy and convenient to use as a portable device or as a spectrum recorder, and includes a free Android/iOS App, internal memory, and a long-lasting rechargeable battery. It is individually calibrated and provides device-to-device repeatability. The features and performance are comparable to conventional industry equipment.
  • The tiny BLE spectroradiometer XL-500 measures and records light spectrum with absolute power values, not only SPD (W/m2/nm) but also PAR/PPFD (umol/m2/s/nm) and DLI measurements for agriculture.
