Can a UVB-1/UVA-1 be used underwater?
Yes. Although mainly used above water, the UVA-1/UVB-1 can handle shallow depths (1 m) for periods of hours to days. The instruments are sealed and have on-board desiccants. You will find that the water’s surface and suspended aquatic material tends to attenuate UV-B data in strange and unpredictable ways, mainly as a function of turbidity. A TSP-700, MFR/UVMFR, or SPUV cannot be used underwater.
