Online ozone analyzer

This equipment is a microcomputer type online ozone measuring instrument for water. It uses an advanced

non-membrane constant voltage sensor that eliminates the need to change diaphragms and medicaments. It

has high sensitivity, fast signal response, accurate measurement, stable performance and easy maintenance


The water ozone measurement and control system has the characteristics of convenient use, high accuracy and 

economy. The use of this series of advanced analytical techniques ensures the long-term reliability and 

reliability of the instrument. 

It has Chinese menu operation, 485 communication and other functions. It can be used for drinking water 

treatment plants, canning plants, drinking water distribution networks, swimming pools, cooling circulating 

water, water treatment projects, etc., to continuously monitor and control the ozone content in aqueous
