Product Description:
The instrument consists of an electrolytic rod with positive and negative electrodes (one is an iron rod and the other is an aluminum rod), two electrodes introduced as electric fields. After electrolysis, positive Fe3+ ions are dissolved under the action of electric current. They will combine with negative OH - ions in water to form Fe (OH) 3 particles which are insoluble in water. These particles have strong coagulation and adsorption activity to colloidal particles in water, and thus form the process of adsorption and coagulation of organic or inorganic substances in water.
At the same time, due to the action of electric current, the original dissolved metal particles, such as manganese, potassium, cobalt and so on, are reduced out and gradually aggregated to form metal clusters, resulting in the color separation of different metal ions.
After electrolysis, different colors of water show various impurities in the water.
Water electrolysis apparatus:
Yellow: dissolved acids, silicon compounds, organic minerals, molybdenum, silicon, fluorides, and other organic matters.
Green: arsenic, mercury, lead, copper and sodium.
Blue: bacterias, viruses, carcinogens, organophosphorus, etc. (fertilizers, detergents and pesticides)
Red: iron, rust and bacterias
White: lead, zinc, mercury, inorganic salt fouling.
Black: heavy metals (zinc, lead, copper, chromium, manganese, cadmium)
Product Information:
Material: ABS+ aluminum iron
Size(Approx.): body length: 10.7*9.7*2.6cm/4.21*3.82*1.02in, power cable length: 80cm/31.50in, iron bar length: 7cm/2.8 cm(2.76*1.10in)
Measuring range: 50 to 200 mg/L.
Rated voltage: 220V/50Hz
Application: household drinking water, water purifier detection.


Usage method:
1.Prepare to test the water-take-two white glasses with a capacity of 100-150 ml, one for tap water, the other for RO water, and put them on the table.
2. Prepare for inspection - put the electrolyzer on the glass and plug in the 220 volt power supply.
3. Test - start the test of the power switch button on the electrolytic cell to the ON (open) position. The usual inspection time is 30 seconds. At the end, switch the power switch to OFF (off), and finally take out the electrolyzer.


Packing list:
1* electrolyzer body
2* aluminum rod
2* iron rod


Attention:
1. After power supply is switched on, hands should not be held on the electrode; fingers should not be put into the test water; children should not be allowed to play with the electrolyte.
2. Dry cloth is used to dry the electrode after the electrolyser is used up, and the water on the iron pole is wiped off with spinning cloth and kept properly.
