LI-COR manufactures a variety of terrestrial and underwater light sensors, each with their own preferred applications. We are often asked if the sensors are interchangeable. For example, can an underwater sensor be used in air?
In general terms, an underwater sensor can be used in air. The same measurement principle applies across the same active wavelengths. The LI-190 terrestrial quantum sensor and the LI-192/193 underwater quantum sensors are cosine corrected silicon photodiodes with a measurement range of 400-700 nm.
