Reef aquariums
Underwater PAR & lighting control
Measure the light your corals actually receive, or control a multi-channel reef LED system.
UV / optical / solar
Specific wavelength & irradiance tools
Measure sunlight UV, 385/405 nm UV, 660/850 nm red/NIR, dental curing light or solar irradiance.
Desire
