How to use the dot analyzer:
1. Prepare water for inspection - take two white glasses with a capacity of 100-150ml, one is connected with piped water, and the other is connected with RO machine water, and drain them on the table.
2. Prepare for inspection - place the electrolytic cell flat on the glass and plug in the power supply.
3. Inspection - press the power switch button on the electrolytic cell to the ON position to start the inspection.
Normally, the inspection time is 30 seconds. At the end, first press the power switch to the OFF position, and then take out the electrolyzer.
Safety warning:
After the power is turned on, do not hold your hands on the electrode; Do not put your finger into the inspection water; Do not let children play with the electrolyzer.
After the electrolyzer is used up, dry the electrode with a dry cloth, and clean the water on the iron pole with a gauze cloth, and keep it properly.
Explain:
This instrument is equipped with electrolytic rods with positive and negative poles (one is iron rod, the other is aluminum rod), namely, two electrodes introduced as electric fields. After the electrolyzer is powered on, under the action of the current, the positive Fe3+ions will be dissolved, and they will combine with the negative OH ions in the water to form insoluble Fe (OH) 3 particles. These particles have strong condensation and adsorption activity for colloidal particles in the water, and thus form the adsorption and condensation process for organic or inorganic substances in the water.
At the same time, due to the effect of current, metal particles that were originally dissolved in water, such as manganese, potassium, cobalt, etc., were reduced and gradually gathered to form metal clusters. Due to the different color development of different metal ions, color separation occurred.
The water after electrolysis appears different colors, indicating various impurities in the water
Water quality electrolysis instrument
Yellow: dissolved acid, silicon compounds, organic minerals, molybdenum, silicon, fluoride, other organic substances
Green: arsenic (arsenic), lead, copper, sodium
Blue: bacteria, viruses, carcinogens, organic phosphorus, etc. (fertilizers, detergents and pesticides)
Red: iron and rust, bacteria
White: lead, zinc, inorganic salt dirt
Black: heavy metals (zinc, lead, copper, chromium, manganese, cadmium)
Criteria for measuring water quality:
1. It does not contain any substances harmful to human body and with 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. PH value is weakly alkaline (7.0-8.0);
4. The content and proportion of trace elements and minerals in the water are moderate and close to the normal liquid;
5. The content of dissolved oxygen and carbon dioxide in water is moderate (dissolved oxygen in water ¡Ã 6-7mg/L)
6. The nutritional and physiological functions of water should be strong (including solubility, permeability, diffusion, metabolism, emulsification, cleaning, etc.).
If the electrode is corroded after being used for a period of time, please polish it gently with fine sandpaper. After polishing, apply a little food oil to prevent rust.
Power supply: AC110V/220V

TDS Pen Instructions:
Remove the pen cover and turn on the ON switch
Put the pen into the test solution, the solution height shall not exceed 2cm
Stir the pen in the solution. When the reading is stable (2-6 seconds), the TDS value will be displayed on the screen. At this time, press the HOLD key to lock the value
After use, wipe off the water on the pen head, clean it with pure water, and then cover the pen cover
Battery: 2 x CR1620 3V battery (not included)
