A. Product Overview
The Metravi TDS-3 Digital TDS Meter is a portable water purity tester designed to indicate the level of Total Dissolved Solids in water or liquid solutions. TDS mainly includes dissolved minerals, salts and ionized solids present in water.
This meter has a 0 to 9990 PPM TDS measuring range, 1 PPM resolution, plus or minus 2 percent accuracy, digital LCD display, titanium alloy electrode, and 0 to 50 degree Celsius temperature measuring range. It is compact, lightweight and suitable for field use. The catalogue also highlights features such as hold function, auto-off after 5 minutes, TDS and temperature measurement, quick results and anti-rust sensor design.
B. Working Principle
The Metravi TDS-3 works by measuring the electrical conductivity of water. Dissolved minerals, salts and ionized solids increase the conductivity of water. The meter senses this conductivity through its titanium alloy electrode and then estimates the TDS value in PPM.
To take a reading, the user immerses the meter into water up to the recommended immersion level, waits for the reading to stabilise and then uses the hold function to save the value for easy reading and recording. The meter also compensates for temperature variation, which helps improve the reliability of the TDS reading.
C. Why It Is Used
The Metravi TDS-3 is used to quickly check water quality and understand the level of dissolved solids present in water. TDS testing helps users identify whether water is suitable for drinking, cooking, aquarium use, plants, RO filtration or general household use.
It is used for:
Checking drinking water quality
Checking RO water quality
Checking tap water quality
Checking filtered water quality
Checking aquarium water quality
Checking bottled water quality
Checking water for plants and flowers
Checking hard water issues
Monitoring purifier output
Deciding when to service or replace filter parts
The catalogue also explains that high TDS water may indicate contamination or hard water, while very low TDS water may taste flat and lack useful minerals. It also includes a TDS level reference table for understanding water quality ranges.
