1. Product Introduce

Dissolved oxygen on-line analyzer is one of the intelligent online chemical analysis instruments. 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 transmissionoutput connection recorder.

It can also be connected to the RS485 interfacethrough the MODBUS RTU protocol. Into the computer for monitoring andrecording.

At the same time, the device has 2 relay interfaces, which can setthe alarm point output.

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 theshortcomings 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.
