I. product overview

Zw-200jk series industrial on-line oxygen dissolver ensures the long-term stability and reliability of the instrument; Automatic determination of electrode zero and slope overrun; Photoelectric coupler isolation protection 4 ~ 20mA signal output, input signal and output signal no interference; EEPROM type memory, no backup battery, no loss of data after power off; Small temperature drift, stable, accurate; The operation menu design is unique, avoids the user tedious operation.

Zw-200jk series industrial on-line oxygen dissolver is incredibly convenient to use; Large screen multi-parameter (dissolved oxygen value, temperature, output current, etc.) LCD backlight display, intuitive and easy to read; 3 minutes backlight off automatically without key operation, which can save electricity and prolong the service life of meter; Adjustable screen contrast level; High and low alarm points can be set arbitrarily; The screen can directly display alarm status and can be accompanied by switch ON/OFF signal output; Arbitrary setting function of hysteresis to avoid frequent action of switch relay; RS485 communication optional.

Ii. Application:

Zw-200jk series industrial on-line oxygen dissolver can be widely used in continuous monitoring of dissolved oxygen value in chemical fertilizer, metallurgy, environmental protection water treatment engineering, pharmacy, biochemistry, food, aquaculture and tap water.

Iii. Main features:

1. All imported chips and components are adopted, and zui new surface sticker production process is adopted to ensure stable and reliable operation of the instrument;

2. Multi-parameter display: PH value, temperature value, high alarm setting value, low alarm setting value, whether the meter is in high or low alarm state, and the current time can be displayed at the same time. Each parameter is clear at a glance;

3. The unique PH value corresponding to 4 ~ 20 mA current output is reversible and can be set at any value, which can bring special convenience to users;

4. Adopt waterproof and gas-proof fully sealed flame-retardant shell, protection grade IP65, which can be used in very bad environmental conditions;

5. RS485 communication (optional);

6, unique history curve function, can record the current 30 days of historical data and query function;

7. The unique design of the operation menu brings great convenience to users, who can also use it freely without reading the manual.
