Industrial Online Dissolved Oxygen Analyzer Water Quality Testing Instrument

Product Description

Product Introduction

This membrane dissolved oxygen online analyzer is an intelligent online chemical analysis instrument, which is widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemistry, food and tap water industries. The dissolved oxygen meter mainly monitors the oxygen content/saturation/oxygen partial pressure and temperature in the solution continuously. The continuous monitoring data is connected to the recorder through the transmission output to realize remote monitoring and recording, and can also be connected to the RS485 interface to communicate with the computer through the Modbus-RTU protocol, so as to realize computer monitoring and recording of the instrument.
