SY-1058 Total Mercury Water Quality Online Detector

1. Working principle: SY-1058 total silver online water quality analyzer Measurement method: In the presence of sodium dodecyl sulfate, silver reacts with 3,5-Br2-PADAP in an acetate buffer medium with a pH of 4.5-8.5 to form a stable red complex with a complexation ratio of 1:2. When the reaction medium is controlled at pH 5, the maximum absorption peak of this complex is at 576nm. The instrument directly displays the total silver value in the sample through colorimetric conversion.

2. The SY-1058 total silver 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 is completed, automatically clean the processing equipment, instrument pipelines, valves and other components;

- 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;
