Ozone Detector

Ozone is a gas that contains three oxygen atoms rather than the two needed to form normal oxygen (O2). This extra atom makes it a potent oxidant that can damage mucus tissues and respiratory systems at high concentration levels. It also is a known air pollutant and irritant. Ozone detection is important to help ensure that people are not exposed to unsafe levels of the gas.

How do you monitor ozone levels?

The Ozone detector works by passing sample and background air alternately through a cell that contains a sensor that absorbs UV light. The amount of light absorbed reveals the ozone concentration according to the Beer-Lambert Law, which states that the absorption is proportional to the concentration.

The sensor used in the ozone detector consists of a piece of gas-sensitive semiconductor material like WO3, SnO2, or In203. When ozone molecules come into contact with the material, they undergo surface redox reactions that change the sensor’s electrical resistance. The change in resistance is a function of the ozone concentration and can be measured with a simple voltmeter.

The ozone gas detector is ideal for use in industrial and commercial applications such as odor control, sterilization workshops, water treatment, and food and medicine production. It has a backlit high-resolution LCD display, and supports multiple alarm functions with customizable settings including sensitivity, selectivity, and battery operation time. It can be powered by a DC 3.7V lithium battery with a battery life of >24 hours. It also comes with an OG-3 ozone source calibrator for calibration verification and approximate ozone generation level determination.
