Pocket TDS Meter

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
• Digital LCD display for clear readings
• Measurement range: typically 0 9990 ppm
• High accuracy (2% full scale)
• Automatic Temperature Compensation (ATC) for precise results
• Hold function to freeze readings
• Auto power-off to conserve battery
• Durable probe sensor with quick response

Working Principle

The device measures the electrical conductivity (EC) of water and converts it into TDS value using a predefined conversion factor. This allows users to estimate the amount of dissolved salts and minerals present in the solution.

Applications

• Drinking water quality testing (RO/UV systems)
• Laboratory and research analysis
• Aquariums and fish farming
• Hydroponics and agriculture
• Swimming pools and water treatment plants
• Industrial and environmental monitoring
