The instrument consists of an electrolytic rod with positive and negative electrodes (one is an iron rod and the other is an aluminum rod), and two electrodes are used as electric field introduction. After electrolysis, the positive Fe3+ ions are dissolved under the action of electric current. They will combine with the negative OH-ions in the water to form water-insoluble Fe (OH) 3 particles. These particles have strong agglomeration and adsorption activity to colloidal particles in water, thereby forming an adsorption and agglomeration process for organic or inorganic substances in water.
At the same time, due to the action of the electric current, the originally dissolved metal particles, such as manganese, potassium, cobalt, etc., are reduced and gradually aggregate 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.
Color identification:
- Yellow: Dissolved acids, silicon compounds, organic minerals, molybdenum, silicon, fluoride and other organic substances.
Easy-to-use. Just put the test pen into the water you want to test and press the button, then the TDS (total dissolved solids) of water shows on the display.
Superb technique, accurate data. Measure water purity accurately, pay close attention to families'health and safety. The lower the TDS the higher purity water has.
Extensively application. You can use it to test the purity of running water, plain boiled water, barreled pure water, cell water, filtered water, aquarium water, and so on.
lowenergy and intelligent. The tester has IPX6 waterproof body and lowenergy chip, it will auto off above 2 minutes nonuse.
It transmits at a constant speed and distinguishes the waves reflected from the back of the instrument.
It can also be widely used in manufacturing, metal processing, commodity inspection and other materials that allow ultrasonic waves.
Ultrasonic thickness gauge is suitable for materials that conduct and reflect constant sound waves, such as metal, plastic, ceramic, glass, etc.
The intelligent hand-held ultrasonic thickness gauge is controlled by microprocessor, which can measure the thickness quickly and accurately, and has the sound of various materials, without the need of ultrasonic measurement damage.
The tool is capable of accurately measuring parts in different materials or industrial production, as well as monitoring pressure vessels in pipes and production equipment, and the degree of corrosion of various parts.
Temperature-added style: You can switch the display temperature by pressing the button. When the temperature is displayed, only the power and temperature can be displayed, but the voltage cannot be displayed.
Color LCD, clear display, accurate measurement
Customize to meet the needs of various battery parameters
The battery voltage can be set, and the battery voltage can be measured in a wide range
