instrument and accessories are damaged by transportation and whether the accessories
are complete. If any abnormalities are found, please contact our after-sales service
department or regional customer service center, and keep the package for return
processing.
This instrument is an analytical measurement and control instrument with highly
precision.Only skilled,trained or authorized person should carry out installation, setup and
operation of the instrument.Ensure that the power cable is physically separated from the
power supply when connection or repair.Once the safety problem occurs, make sure that
the power to the instrument is off and disconnected.
For example, it may insecurity when the following situations occur:
1)) Apparent damage to the analyz
2)) The analyzer does not work properly or provides specified measuremen .
3)3)The analyzer has been stored for a long time in an environment where the temperatu
exceeds 70 °C.

The analyzer must be installed by professionals in accordance with relevant local
specifications, and instructions are included in the operation manual.
Comply with the technical specifications and input requirements of the analyzer.
Features
Fluorescence industrial online dissolved oxygen meter is an online water quality
monitoring and control instrument with microprocessor. The instrument is equipped with
fluorescence dissolved oxygen sensors. It is widely used in power plants, petrochemical
industry, metallurgical electronics, mining, paper industry, food and beverage industry,
environmental protection water treatment, aquaculture and other industries. The dissolved
oxygen value and temperature value of water solution are continuously monitored and
controlled.

Instrument connection
Electrical connection
Connection between instrument and sensor: Connection of power supply, output signal, relay
contacts and instrument baseplate. The cable length of sensors is usually 5-10 meters. There are
labeled inserts at the end of the cable, which can be inserted into the terminal with the same
digital symbols on the instrument roof and tightened.
