KL-1393 Pen-Type TDS Meter

TDS meter is the abbreviation of "Total Dissolved Solid" in English, meaning the total amount of dissolved solids. Total dissolved solids refer to the sum of inorganic salts and organic matter dissolved in water. Its main components include calcium, magnesium, sodium, potassium ions, carbonate ions, bicarbonate ions, chloride ions, sulfate ions, and nitrate ions. Therefore, a TDS meter is an instrument for measuring the total dissolved solids. The unit of the TDS meter is ppm (i.e., mg/L), and its value is defined as a certain proportional number of the conductivity value, generally taken as around 0.7. The reference temperature for automatic temperature compensation of the TDS meter is generally 25°C, and the temperature coefficient is generally 2%/°C.


This product has the following features:
Large LCD screen—more than twice the size of similar products, with clear display values;
Reasonable design—the electrode at the pen tip can be directly inserted into the mouth of a drinking water bottle for measurement, and the pen cap can serve as a container for the liquid being tested, making it extremely convenient to use;
Fast measurement—due to the精巧裸式的传感元件, it takes 5-30 seconds to complete one measurement;
Easy cleaning—the electrode护套 can be removed, making it easy to clean the probe and护套.
This product measures quickly and accurately, with a durable外壳 that is not easily damaged.
