| 1.Adopt single-chip computer control, menu operation, convenient and simple; |
| 2.Supporting the measurement of dissolved oxygen concentration value, dissolved oxygen saturation and temperature value of water samples; |
| 3.With automatic temperature compensation function, support zero oxygen calibration, fullness calibration and barometric pressure calibration; |
| 4.With isolated output (4~20)mA DC signal, output upper limit and output lower limit can be adjusted steplessly; |
| 5.With isolated (RS-485) digital signal output; |
| 6.With automatic upper and lower limit alarm function; |
| 7.With data retention function, i.e., when the instrument carries out other work such as automatic cleaning function, the original measurement data is kept on the display, and the new measurement data is displayed after the instrument resumes the normal measurement state. |
| 8.Setting three control relays, except for two for outputting upper and lower limit alarm signals, the remaining one relay can be set at will for its suction and release time to realize the automatic cleaning function of the instrument. |
| 9.With measurement data storage and query function, it can store 2000 measurement data (including measurement value and storage time). |
| 10.Plate-mounted or wall-mounted installation, easy to operate and maintain. |
