Portable Ozone Detection

Ozone (O3) is a type of natural colourless gas with a strong, pungent odour. Ozone gas is highly reactive and has strong oxidising properties which can be particularly irritating to the eyes and respiratory system. This hazardous gas can be detected with the robust reliable ozone detectors on our website.

Portable Ozone Detectors

Portable ozone gas detectors measure the concentration of ozone in the air. These analysers can measure ozone in the air to provide a parts per million (ppm) concentration. As an unstable gas, ozone has a unique nature that must be considered during detection. Ozone gas decays to form oxygen as a function of temperature, humidity, time, and air agitation. Therefore, it can be tricky to measure ozone in a consistent fashion.


Ozone is a non-flammable gas that is typically colourless to blue in colour. It has a very pungent odour.


Ozone attacks the eyes and respiratory system and can cause pulmonary oedema. Victims should be removed from the area immediately and given 100% oxygen. When 0.1ppm of ozone is inhaled for two hours, the lung capacity can decrease by 20% or so. Headaches or bronchitis may result when a concentration of 1ppm is inhaled for six hours.

Where is it found

Ozone is commonly found in wastewater treatment plants, power generation plants and uses include sterilisation, disinfection, bleaching, and as an oxidant and such in organic synthesis. Ozone is typically formed around high-powered electrical equipment where sparking is evident such as welding.

Interesting Fact

Although the ozone layer in the atmosphere (approximate O3 concentration: 0.005ppm) protects the earth from the sun’s ultraviolet light, at ground level in coastal regions (where ultraviolet light is particularly intense) 0.05ppm of ozone can be found.

What are Portable Ozone Detectors?


A portable ozone detector is a device that is used to measure the concentration of ozone in the air. Ozone is a gas that is present in the Earth’s upper atmosphere and is known for its strong oxidizing properties.

However, at ground level, ozone can be harmful to human health and the environment. Portable ozone detectors are often used by environmental professionals to monitor air quality and identify sources of ozone pollution. They are typically small and lightweight, allowing for easy transportation and use in a variety of settings.

How to use Portable Ozone Detectors?


 To use a portable ozone detector, first turn on the device and allow it to warm up for the recommended amount of time, as indicated in our instructions. Next, place the detector in the area where you want to measure the concentration of ozone. The device will automatically take readings at regular intervals and display the results on a digital screen or display.

It is important to follow our instructions for using the portable ozone detector, as different models may have different operating procedures. Additionally, you should take care to avoid exposing the detector to extreme temperatures or moisture, as this can affect its performance and accuracy. Finally, be sure to regularly calibrate the device according to the manufacturer’s recommendations to ensure that it continues to provide accurate readings.

Portable ozone detectors are clipped onto workers to provide personal protection, ensuring safe exposure levels. For example, ozone is used to disinfect aircraft. When workers are cleaning, portable ozone detectors provide protection from elevated levels of ozone exposure.


There are several benefits to using portable ozone detectors:

1) Portable ozone detectors are small and lightweight, making them easy to transport and use in a variety of settings.

2) These devices are able to provide real-time readings of ozone levels, allowing for quick and accurate monitoring of air quality.

3) Portable ozone detectors are typically easy to operate, requiring minimal training and technical expertise.

4) The use of these devices can help identify sources of ozone pollution and take corrective action to reduce exposure and protect human health and the environment.
