Dissolved Ozone Analyzer

DISSOLVED OZONE ANALYZER

Detection principle: UV dual path absorption method, used for analysis and detection of dissolved ozone water concentration in tap water, pure water, or semiconductor industry.

Measurement range: 0-20ppm; 0-50ppm; 0-100ppm; 0-120ppm; 0-180ppm; 0-200ppm.

Product features: This UV dissolved ozone analyzer has an internal light source automatic adjustment function, which can adjust the brightness of the LED light source in real-time based on the reference light data of the zero point to ensure the stability of the zero point. This UV optical ozone water concentration analyzer can be connected in parallel or series to the dissolved ozone water pipeline, mainly used for the analysis and detection of dissolved ozone water concentration in tap water, pure water, or semiconductor industries.

This dissolved ozone analyzer has an automatic adjustment system function with a UV light source, which can adjust the brightness of the UV LED light source in real-time according to the reference light data to maintain constant zero point data, ensuring the stability of the zero point. It is a patented product of our company. This UV optical ozone water concentration analyzer can operate continuously without stopping for 24 hours.

Dissolved Ozone Analyzer - Product Overview

The dissolved ozone concentration analyzer is a direct measurement of ozone content in ultrapure water or constant turbidity water using ultraviolet spectrophotometry. The customizable version is HF, which can be used for 20% hydrofluoric acid ozone aqueous solution. Materials in contact with ozone water include PTFE, FFPM, PFA, and quartz or sapphire. The UVOZ-180W dissolved ozone water concentration analyzer is equipped with an inlet and outlet, and is equipped with a touch screen operation interface. The output is directly connected to the PLC with 4-20mA and RS-485 signal lines.

The dissolved ozone concentration analyzer has an automatic adjustment system function with a UV light source, which can adjust the brightness of the UV LED light source in real-time according to the reference light data to maintain constant zero point data, ensuring the stability of the zero point. It is a patented product of our company. This ozone analyzer can operate continuously without stopping for 24 hours. The superior stability of this ozone concentration analyzer is achieved through the use of a true dual beam optical system and an extremely long-lived ultraviolet LED light source.

The shell of the dissolved ozone concentration analyzer is an aluminum shell with splash proof design, protection level: IP65, size: 260x160x90mm (WxHxD), and weight of about 3 kilograms. This dissolved ozone water concentration analyzer can be wall mounted, with a hook design on the back. When installation is required, four mounting brackets are provided.

The inlet flow rate of the dissolved ozone water concentration analyzer is 200-300ml/min. If flow control is required, a throttle valve or flow meter must be installed at the outlet of the dissolved ozone water concentration analyzer. This throttle valve must be positioned behind the sensor (never in front of it! Installing a throttle valve at the inlet will generate bubbles, so it is strictly prohibited for ozone water with water bubbles to enter the dissolved ozone water analyzer.)

It is necessary to maintain the cleanliness of the inlet water of the dissolved ozone water concentration analyzer, and to maintain the cleanliness of the internal sensors of the dissolved ozone water analyzer. It is recommended to calibrate the zero point of the dissolved ozone water concentration analyzer every 2 weeks. When calibrating the zero point, clean water without ozone or color should be introduced
