Device for measuring dissolved salts | TDS Pen Meter

Total Dissolved Solids measuring device A remarkable tool for home and professional use to determine the percentage of salts and minerals in drinking water, and it is ideal for a variety of professional and household uses such as drinking water, especially water used in preparing coffee. Be sure to know the purity level of the water used with the coffee machine to maintain the taste of the perfect cup, and most importantly to prevent corrosion of the machine caused by salts. What is TDS? Total Dissolved Solids is usually abbreviated as TDS and expresses the amount of organic and inorganic materials contained in a liquid, whether suspended particles in molecular or ionic form. This term is often used when dealing with water to describe its suitability for drinking or for steam boilers. The amount of dissolved materials is measured in parts per million ppm, which is milligrams per liter. TDS levels in water: 0 - 50 PPM: Ideal drinking water 50 - 100 PPM: Carbon filtration water 100 - 200 PPM: Hard water 200 - 300 PPM: Acceptable 300 - 400 PPM: Tap water 400 - 500 PPM: Mineral water 500 PPM and above: Not recommended for drinking. Specifications: Device TDS range: (0 - 990 PPM) Accuracy: +/- 2% Battery: 2*1.5V Usage instructions: Maximum immersion level 4 centimeters. Do not store the meter in high temperatures or direct sunlight.
