| 1.Membrane amperometric measurement principle, using the overlay method of three electrode type constant current measurement system, applicable to a variety of water quality conditions, can withstand surfactant components; |
| 2.Adoption of single-chip computer control, menu operation, convenient and simple; |
| 3.It can measure the residual chlorine value and temperature value, or total chlorine value and temperature value of water samples; |
| 4.With automatic temperature compensation function, support DPD method comparison calibration; |
| 5. Isolated output (4~20)mA DC signal, upper and lower output limits can be adjusted steplessly; |
| 6. Isolated (RS-485) digital signal output; |
| 7.With automatic upper and lower limit alarm function; |
| 8.With data retention function, i.e., when the instrument is doing other work such as auto-cleaning function, the original measurement data will be kept on the display, and the new measurement data will be displayed after the instrument resumes the normal measurement state; |
| 9.With storage and query function, it can store 2000 sets of measurement data; |
| 10. Plate-mounted or wall-mounted installation is available, which is convenient for installation, operation and maintenance. |
