1. Product Introduce

Dissolved oxygen on-line analyzer is one of the intelligent online chemical analysisinstruments. And continuous monitoring of temperature.This product uses a fluorescent method of dissolved oxygen probe. The sensor producthas a long life, no maintenance, and excellent performance.

Continuous monitoring data can be remotely monitored and recorded through the transmission output connection recorder. It can also be connected

to the RS485 interfacethrough the MODBUS-RTU protocol.

2. Product Features

This product probe is a fluorescence method probe, which uses the principle of fluorescence quenching for measurement. The fluorescence method

has been active in recent years and can overcome the shortcomings of traditional classic measurement methods that cannot be measured online

continuously. Electrodes have high sensitivity, low detection limit,long life, and have been widely used in the advantages of sustainable online

monitoring.
