Water Quality Electrolyzer Tester

Testing method: 

Prepare two transparent cups of water (100 to 150 ml ) one cup holds tap water, the other cup holds RO water. 
Place electrodes into water before powering ON and begin the test, After 30 to 60 seconds, turn it off and remove the water electrolyzer. 

Caution: Avoid electric shock while using the devise; Do not touch the rods or put your finger into water once the precipitator is plugged into an electric outlet. Do not use metal containers to hold the water. 

Testing Analysis Results: 
Black: Heavy Metals 
Yellow: Dissolved acids, fluoride and other organic matter 
Green: Arsenic, mercury, lead, copper, sodium 
Blue: Bacteria, viruses, carcinogens, chemical fertilizers, pesticides, etc. 
Red: Iron, rust and bacteria 
White: lead, zinc, mercury, inorganic dirt
