Shanghai Yidian Thunder Magnetic SJG-209 Online Optical Dissolved Oxygen Monitor

Shanghai Yidian Thunder Magnetic SJG-209 Online Optical Dissolved Oxygen Monitor

【 Application Fields 】

N is particularly suitable for online monitoring of dissolved oxygen values in industries such as environmental protection and sewage treatment, such as online monitoring of dissolved oxygen values in aeration tanks of sewage treatment plants;

N is also suitable for water quality monitoring in different fields such as environmental protection industry, tap water source monitoring, and aquaculture farms.

【 Main Features 】

N adopts microcontroller control, menu operation, convenient and simple;

Support measuring the dissolved oxygen concentration, dissolved oxygen saturation, and temperature values of water samples;

N has automatic temperature compensation function, supporting zero oxygen calibration, full-scale calibration, and pressure calibration;

N has an isolated output (4-20) mA DC signal, and the upper and lower output limits can be infinitely adjusted;

N has isolated (RS-485) digital signal output;

N has automatic upper and lower limit alarm functions;

N has a data retention function, which means that when the instrument is performing other tasks such as automatic cleaning, the original measurement data is retained on the display screen, and new measurement data is displayed after the instrument returns to normal measurement state.

Set up three control relays, except for two for outputting upper and lower limit alarm signals, the other relay can be freely set for its suction and release time to achieve automatic cleaning function of the instrument.

N has the function of storing and querying measurement data, which can store 2000 measurement data (including measurement values and storage time).

N disk mounted or wall mounted installation, easy to operate and maintain;

The protection level of the n chassis is IP65.
