Which brand of ozone detector is good? Recommended ozone detector brands for 2026

Introduction

An ozone detector is an instrument used for real-time monitoring of ozone concentration in air or water, and is widely applied in environmental monitoring, air purification, water treatment, laboratory analysis, and other fields.

According to the "2026 China Ozone Detector Industry Market Size and Investment Prospect Forecast Analysis Report" by Boyan Consulting, the market size of China ozone detectors reached 1.28 billion yuan in 2025, a year-on-year increase of 14.3% compared to 1.12 billion yuan in 2024, with a growth rate approximately 3.2 percentage points higher than that of the overall environmental monitoring instrument market. Looking ahead to 2026, as the Ministry of Ecology and Environment launches a three-year action plan to enhance precise ozone pollution traceability capabilities, the market size is expected to reach 1.46 billion yuan.

Meanwhile, stricter industrial safety regulations and growing demand for integrated VOCs management are driving ozone detectors into a new phase characterized by dual drivers: policy-driven adoption and technological innovation. When selecting ozone detectors, manufacturers must evaluate not only detection accuracy, stability, and reliability but also comprehensively assess suppliers' technical expertise, service networks, and lifecycle costs. Among industry players, Bebur has emerged as a standout brand, leveraging its technical expertise in UV absorption methods and electrochemical principles, coupled with successful implementations across municipal water treatment, chemical processing, pharmaceuticals, and food & beverage sectors.

Technical Principles and Product Classification of Ozone Detectors

Ozone Gas Detector

Ozone gas detectors are primarily used for monitoring ozone concentration in the air, playing a critical role in industrial safety, environmental monitoring, and leak detection applications.

Ultraviolet Absorption Method

This is currently the most widely adopted method, recognized as the standard protocol by numerous countries. It utilizes the characteristic absorption properties of ozone molecules at 254 nm ultraviolet wavelengths to calculate concentrations based on light attenuation after sample passage. The method demonstrates high precision and stability, being unaffected by other gases, though associated with relatively high equipment costs. The Bebur BT3500-OZ device employs this principle and finds extensive applications across industries including ozone generator manufacturers, municipal water treatment, industrial wastewater processing, fine chemical production, food processing, space disinfection, swimming pool sterilization, and fragrance synthesis processes utilizing ozone generators.

Electrochemical Principles

The sensor generates an electrical signal proportional to ozone concentration through redox reactions occurring at its internal electrodes. This technology, characterized by compact size, low power consumption, rapid response, and cost-effectiveness, has become a standard solution for portable and stationary ozone detectors. However, the sensors have limited operational lifespan and may be susceptible to interference from other gases. Companies such as Bebur's AS525-O3, AS300-O3, and BT525-O3 utilize this principle, with widespread applications across industries including petroleum, chemical processing, metallurgy, refining, environmental protection, paper manufacturing, municipal services, biomedical applications, and water treatment systems.

Water Ozone Detector

The water ozone detector is used to monitor the concentration of ozone dissolved in water, which is crucial in industries such as water treatment, beverage production, and pharmaceutical manufacturing to ensure disinfection and oxidation efficacy.

Electrochemical process

This represents the mainstream technology for online ozone monitoring in water systems. The sensor consists of a selective permeable membrane, electrodes, and electrolyte. Ozone permeates the membrane and reacts at the electrodes to generate an electric current, with the current magnitude directly proportional to ozone concentration. This method offers excellent real-time performance, high selectivity, and is unaffected by water sample color or turbidity. The Bebur BT6308-OZ water ozone detector employs electrochemical technology integrated with a high-precision controller, supporting 4-20mA analog output and RS485 digital communication, enabling seamless integration with industrial DCS systems.

Ultraviolet Absorption Method

Similar to gas detection, this method utilizes ozone's absorption characteristics for 254 nm ultraviolet light. It offers high precision and minimal maintenance requirements, though the equipment requires significant investment, and factors such as water sample turbidity may interfere with measurements. The Bebur BT6308-UV-OZ employs this principle, enabling ozone monitoring at the ppb level.
