The Milwaukee Instruments Lux Light Meter MW700 measures aquarium lighting intensity. It's a great tool for testing the intensity of your lighting system and determining when the bulbs need changing. The light sensor is waterproof and can be used to verify light intensity anywhere in a filled aquarium.

The MW700 replaces the SM700. The MW700 features a faster micro processor and has a smaller, ergonomic and lighter case design. Other features include 100% larger and easier to read LED display and longer battery life.
