Water Quality Tester Household Electrolyzer Level Meter Testing Tool

Water Quality Tester - Household Electrolyzer Test, Digital Electrolysis Water Tools with Water Purity Level Meter, Water Purity Tester, Quick PH Testing Tool for Drinking Water / Cleaning / Hydroponics / AquariumsSpecification:Packing: White boxSize: 12.5*7*3cm/4.92*2.75*1.18inUsage Tips:Prepare water for inspection-Take two white glasses with a capacity of 100 ~ 150 ml, one for tap water and the other for RO machine water, and discharge them on the table.Prepare for inspection-Place the electrolyzer flat on a glass and plug in a 220 volt power supply.Inspection: Press the power switch button on the electrolyzer to the ON position to start the inspection.Usually, the inspection time is 30 seconds. At the end, first press the power switch to the OFF position, and finally take out the electrolyzer.Water quality electrolyzer:Yellow: dissolved acid, silicon compounds, organic minerals, molybdenum, silicon, fluoride and other organic matters.Green: arsenic (arsenic), mercury, lead, copper and sodium.Blue: bacteria, viruses, carcinogens, organic phosphorus, etc. (chemical fertilizers, detergents and pesticides).Red: iron and rust, bacteria.White: lead, zinc, mercury, inorganic salt dirt.Black: Heavy metals (zinc, lead, copper, chromium, manganese and cadmium).Standard for measuring water quality:1. It does not contain any substances that are harmful to human body and have peculiar smell (especially heavy metals and organic substances);2. The hardness of water is moderate, usually between 50-200mg/L (calculated by calcium carbonate);3. The PH value is weakly alkaline (7.0-8.0);4. The content and proportion of trace elements and minerals in water are moderate, which is similar to that of normal liquid.5. The content of dissolved oxygen and carbon dioxide in water is moderate (dissolved oxygen in water 6-7 mg/L).6. The nutritional and physiological functions of water are strong (including solubility, permeability, diffusion, metabolism, emulsification and cleaning power, etc.).(Different colors of electrolyzed water show various impurities in water.)Color display Yellow: dissolved acid, silicon compounds, organic minerals, molybdenum, silicon, fluoride and other organic matters.Green: arsenic (arsenic), mercury, lead, copper and sodium.Blue: bacteria, viruses, carcinogens, organic phosphorus, etc. (chemical fertilizers, detergents and pesticides).Red: iron and rust, bacteria.White: lead, zinc, mercury, inorganic salt dirt.Black: Heavy metals (zinc, lead, copper, chromium, manganese and cadmium).If the electrode corrodes after a period of use, please polish it lightly with fine sand paper. After polishing, you can apply a little food oil to prevent rusting.Note:After turning on the power supply, hands shall not be caught on the electrodes; Do not put your fingers into the test water; Don't let children play with the electrolyzer.After using the electrolyzer, dry the electrode with dry cloth, wipe the water on the iron pole with fine gauze, and keep it properly.Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank youPlease allow 1-2cm measuring deviation due to manual measurement.Package Included:1 X Water Quality Tester Electrolyzer
