Radiometric Probe for UVA Irradiance
LPUVA03…Series
-
The LPUVA03 probe measures irradiance (W/m²) defined as the ratio between the radiant flux (W) passing through a surface and the surface area (m²) in the UVA (315 nm…400 nm) spectral range. Thanks to a new type of photodiode, LPUVA03 is blind to visible and infrared light.

Spherical Underwater Quantum Sensor
LI-193
-
The LI-193 Spherical Quantum Sensor measures PAR in air or underwater from all directions at depths up to 350 meters. This sensor is useful for studies of phytoplankton, which uses radiation from all directions. The measurement is referred to as Photosynthetic Photon Flux Fluence Rate (PPFFR) or Quantum Scalar Irradiance.
