1. Very Easy to operate , quick testing, obvious results. simplest and cheapest way to test the water quality. buy your self & see the condition of your drinking water. 2.The electronic color tester is an effective sales tool that visually demonstrates the difference between high TDS water and low TDS water Testing methods (1) Prepare two transparent cups of water (100 to 150 ml ) one cup holds tap water, the other cup holds RO water. (2) Put metal pillar into two cups, turn ON and begin the test, After 30 to 60 seconds, turn it off and remove the water electrolyzer. (3) Caution: Avoid the electric shock while using the devise; Do not touch the rods once the precipitator is plugged into an electric outlet. 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 Package Included: 1 Piece US Plug Water Electrolyzer

Features: 100% brand new and high quality.
This meter can test electric field radiation and magnetic field emission to reach the optimal test result. It is used to test and learn electromagnetic radiation situation indoor and outdoor.
It is equipped with a built-in electromagnetic radiation sensor, which can display the radiation value on the LCD digital display after processing by control micro-chip. One instrument with two uses, it can test the electric field and the magnetic field radiation at the same time. Sound-light alarm, when the test result exceeds the safe value, the instrument will alarm automatically. Data locking, one-key lock of the radiation value. LCD display of the values for easier reading. Radiation assessment, remind you whether the radiation value is safe or not. Fashionable design, easy on-hand operation, it’s easy to carry and make field measurement.
