About Pocket TDS Meter
A Pocket TDS Meter (Total Dissolved Solids Meter) is a compact, portable device used to measure the concentration of dissolved solids in water, expressed in parts per million (ppm). It operates on the principle of electrical conductivity, providing quick and accurate readings for water quality analysis.
Designed for ease of use and portability, this pen-type digital instrument is widely used in laboratories, water treatment plants, aquariums, hydroponics, and domestic water testing applications.
Key Features
- Compact, lightweight, and pocket-size design
