Total arsenic CHWJ - 2024 type online water quality analyzer

DEK-2024 型总砷在线水质分析仪

A functional description
1. How it works: CHWJ - 2024 total arsenic online water quality analyzer measurement method using ISO6595, GB - 7485-87 "water quality - determination of total arsenic - silver diethyl dithiocarbamate spectrophotometry". Zinc and acid, generate new ecological hydrogen in the presence of potassium iodide and stannous chloride pentavalent arsenic reduction for trivalent trivalent arsenic is nascent hydrogen reduction into hydrogen arsenide (arsine) using silver diethyl dithiocarbamate triethanolamine chloroform liquid absorption arsine generate colloidal silver in 530 nm wavelength red absorption solution's absorbance measurement. Instrument will directly by color conversion total arsenic value displayed in the samples.

2. The total arsenic CHWJ - 2024 type online water quality analyzer has the following basic functions:
- display the time can be set, proofreading, including year, month, day, and when,;
- with a power device, leakage of the instrument, sample can't import the reactor system alarm and display abnormal conditions such as fault. Stop running until the system is restarted at the same time;

- each time after the measurement, automatic cleaning device, instrument piping, valves and other components;
- protection of cutting off power and water and electricity, the coming water automatic recovery function;
- do regular cleaning, regular sample function;
- touch screen to view more intuitive, more convenient operation;
