1Prepare to test the water.——Take two containers with a capacity of100～150A glass of milliliters of white glass, one cup of tap water, and another cup of "Republic of the PhilippinesThe machine water is placed side by side on the table.
   2Prepare for inspection.——Plug the electrolyzer onto the glass cup and place it flat on the glass.220Voltage power source.
   3Inspection——Press the power switch button on the electrolyzer towardONStart the inspection at the (open) position.
   The usual time for inspection is30Second. When the end of the time, first press the power switch toOFFThe position of the switch, and finally remove the electrolyzer.
  
  Safety Warning
   After turning on the power, do not grasp the electrodes with both hands; do not insert fingers into the test water; do not allow children to play with the electrolyzer.
   After the electrolyzer is used up, use a dry cloth to wipe the electrodes clean, and use a fine sandpaper to wipe off the water from the iron pole, and then properly store it.
  
  Explanation
   This instrument is equipped with an electrolytic rod with a positive and negative pole (one is a iron rod, the other is an aluminum rod), which serve as the two electrodes introduced into the electric field. After the electrolyzer is powered on, under the action of the current, positive ions are dissolved out.Fe3+Ions, they will react with the negative charges in water.OH-Ion binding forms insoluble in water.Fe(OH)3Particles, these particles have a strong ability to coagulate and adsorb colloidal particles in water, and thus form an adsorption and coagulation process for organic or inorganic substances in water.
   At the same time, due to the action of the current, the original metal particles dissolved in water, such as manganese, potassium, cobalt, and so on, are reduced and gradually aggregate to form metal masses. Since the color of different metal ions is different, color separation occurs.
   The water after electrolysis shows different colors, indicating the various impurities in the water.
  Water Quality Electrolysis Instrument——
  yellow:Dissolved oxygen, silicates, organic minerals, molybdenum, silicon, fluoride, other organic compounds

  red:Iron and rust, bacteria
  white:Lead, zinc, mercury, inorganic salt dirt
  black:Heavy metals (zinc, lead, copper, chromium, manganese, cadmium)
      
  Standards for measuring the quality of water
   1、does not contain any harmful or unpleasant-smelling substances (especially heavy metals and organic compounds);
   2、水的软硬适度，通常介于50－200 milligrams per literBased on calcium carbonate")"";
   3andPHThe value presents a weakly basic nature.7.0－8.0between
   4The content and ratio of trace elements and minerals in water are moderate, similar to that of normal fluids.
   5The content of dissolved oxygen and carbon dioxide in water is moderate (the content of dissolved oxygen in water should be between 5-8 mg/L, and the content of carbon dioxide should be between 10-30 mg/L).≥6－7mg/L）
   6The nutritional and physiological functions of water are stronger (including solubility, osmosis, diffusion, metabolic, emulsification, and cleaning power, etc.)
