What are the types of ozone concentration detectors?
There are three main types of ozone concentration detectors commonly available on the market. When selecting one, you can make your choice based on your specific testing requirements, taking into account factors such as measurement accuracy, application scenarios, measurement range, or testing methods.

1. Fixed ozone concentration detector:
Fixed ozone detectors consist of a gas-sensing alarm controller and fixed ozone detectors. The gas-sensing alarm controller can be placed in the duty room to monitor and control various monitoring points. The ozone detectors are installed in areas where gases are prone to leakage; their core component is the gas sensor. Fixed ozone-sensing alarms are widely used in environments such as petroleum, chemical industry, metallurgy, power generation, coal mines, and water treatment plants, playing an important role in gas protection.
2. Portable ozone concentration detector:
The portable ozone detector is designed to safeguard human life. It’s compact and lightweight, easily clip-on to belts, shirt pockets, or hard hats, and can detect the concentration of ozone gas even in extreme environmental conditions. If the detector senses that the gas concentration in the air exceeds safe levels, it immediately triggers a triple alarm—audible, visual, and vibration—that effectively prevents poisoning incidents caused by excessively high ozone concentrations in the air.
3. Ozone Concentration Detector for Pump Inlet
The pump-suction ozone detector uses a built-in oil-pump to quickly detect the ozone concentration in the working environment. Equipped with an imported electrochemical sensor, this detector features a large, highly visible LCD display and audible and visual alarm alerts, ensuring that even in extremely harsh working conditions, hazardous gases can be detected promptly, thereby providing protection for operators.
The first-level calibration specifications for ozone monitoring standardize environmental facilities. For example, during calibration, the temperature must be maintained between 15 and 30°C, with fluctuations not exceeding ±1°C. Relative humidity should be kept between 10% and 50%. For standard instruments used for ozone measurement, requirements include having a product nameplate and ensuring that the instrument’s surface is intact.
During the calibration process, set more than seven concentration points across the entire range of the ozone transfer standard (including zero concentration and six concentration points at different gradients). For each concentration point, the reading should be the average of 10 repeated measurements, and the standard deviation of these 10 repeated measurements should be less than 2 nmol/mol. First-level ozone monitoring calibration requires performing multi-point calibration more than six times over a period of at least three days. After completing the daily calibration, use an air blower to purge the system with zero-air for at least 10 minutes to remove any residual ozone gas remaining in the pipeline system.
The monitoring values from the ozone standard reference photometer are plotted on the horizontal axis, while the response values from the ozone transfer standard are plotted on the vertical axis. A calibration curve is established using the least-squares method, and the slope and intercept of the calibration curve are recorded. For multi-point calibration, each slope ratio must fall between 0.97 and 1.03, and each intercept point must lie within the range of (0–3) nmol/mol. The relative standard deviation of the slope for multi-point calibration should be no more than 3.7%, and the standard deviation of the intercept points should be no more than 1.5 nmol/mol. Otherwise, the cause must be identified, the ozone transfer standard must be repaired, and then calibration should be performed again.
