More information about our ozone detectors

What is ozone?

Ozone is an allotrope of oxygen. At room temperature, it is a light blue gas with a special smell.
Ozone mainly exists in the ozone layer in the lower stratosphere 20 kilometers from the earth’s surface, and the content is about 50 ppm. It absorbs short-wave ultraviolet rays that are harmful to the human body and prevents them from reaching the earth, to shield the earth’s surface organisms from being harmed by ultraviolet rays.


The content of ozone in the air is beneficial to the human body when the content of ozone in the air is less than one part per million. Because a small amount of ozone can stimulate the central nervous system, accelerate blood circulation, increase the amount of active oxygen in the blood, and activate cells, but high concentrations of ozone can make people feel uncomfortable, and even cause reversible harm to the human body, so the amount of ozone must be controlled.

What is an ozone meter?

The ozone meter is an instrument for measuring the ozone content in the environment, using electrochemical principles to directly display the measured value.

What are the types of ozone detectors?

The ozone detectors on the market can be divided into two main categories, diffusion ozone detectors and pump suction ozone detectors. Our company provides three types of ozone detectors according to different customer usage scenarios: portable ozone detector, fixed ozone detector, and wall-mounted ozone detector.

How should the ozone gas detector be calibrated?

First, place the ozone detector in an ozone-free environment, check whether the measured value is zero, if it is not zero, you need to manually adjust the zero. Secondly, an ozone generator is used to create an ozone environment, and the measured value of the ozone detector is compared with the measured value of the higher precision ozone detection equipment of the same range.

How long is the service life of the ozone detector?

Under normal use, the life of the ozone detector is 3-5 years.

How to export the stored data of the ozone detector?

The suitcase is equipped with a USB data cable, and the stored data of the ozone detector can be exported to the computer through the USB data cable.

How to download the manual of RS-MG41-O3 ozone detector?

To protect the patented technical parameters, please contact us for a manual.

When does the ozone detector need to be charged?

When the power is lower than 10%, the device will sound an alarm (sound and light vibration) every two minutes until the device shuts down.
When the device is off, connect the charger to the portable tester, and the other end to the AC220V AC power supply. After the tester is fully charged, the battery is full and it can be used normally.
