## Description

LED bargraph changes color as ozone levels increase: green indicates a safe level, yellow is caution level, and red is the danger level. Features a heated metal oxide semiconductor (HMOS) sensor for excellent sensitivity and quick response time. Also features an audio alarm and relay output that are triggered at 0.1 ppm (danger level) and a 0 to 3 VAC recorder output. Order optional calibrator to verify that your ozone detectors are conforming to their origianl calibration.

Review: Simple and nice looking indicators - 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.
