C-30ZX Ozone Monitor with Alarm

The media could not be loaded. Here is a video of the sensor in action when I move the C-30ZX detector close to the ozone coming out of my reef aquarium's protein skimmer with the skimmer's carbon hose disconnected. The C-30ZX has a nice response time and the indicator is intuitive and easy to see from a distance when it reaches the various green, yellow, and red levels. There is no setup involved (unless you're adding a relay or changing alarm settings), just plug it in, let it warm up, and then it starts taking the readings! It is compact and looks nice on the wall.

Great unit
