SY-1073 Total Lead Water Quality Online Detector

1. Working principle: The measurement method of SY-1073 total lead online water quality analyzer adopts GB-7470-87 "Water Quality - Determination of Lead - Dithizone spectrophotometric method". In a reducing medium of ammonium citrate and cyanide with a pH of 8.5-9.5, lead reacts with dithizone to form a pale red dithizone lead chelate that can be extracted by chloroform. The chloroform mixed color solution is extracted at a wavelength of 5l0nm, and the instrument directly displays the total lead value in the sample through colorimetric conversion.

2. The SY-1073 total lead online water quality analyzer has the following basic functions:

-Can set and verify display time, including year, month, day, hour, and minute;

-It has an alarm function and displays the fault content in case of system abnormalities such as equipment power failure, instrument leakage, and inability to import samples into the reactor. Simultaneously stop running until the system is restarted;

-After each measurement, the equipment, instrument pipelines, valves, and other components are automatically cleaned and processed;

-Automatic protection for power and water outages, as well as automatic recovery for incoming and outgoing power;

-Regular cleaning and sampling functions;

-Touchscreen viewing is more intuitive and easier to operate;
