Water quality plays a vital role in industries like RO plants , water treatment , pharmaceuticals , textiles , and food processing. Two essential tools that help maintain quality standards are the TDS meter and the PH meter. The TDS meter measures Total Dissolved Solids ( TDS ) in parts per million ( PPM ) , while the PH meter measures acidity or alkalinity on a scale of 0 to 14. Together , they ensure that water is safe , compliant , and suitable for its intended use.
For B2B buyers searching for the best TDS meter price in India or authentic PH meters for industrial applications , understanding their functions , price factors , and buying options is crucial.
TDS stands for Total Dissolved Solids. A TDS meter measures salts , minerals , and impurities dissolved in water. The lower the reading , the purer the water. Drinking water ideally falls between 0– 50 ppm , while most industrial processes accept levels between 50– 150 ppm. Anything above 500 ppm indicates high contamination and is generally unsuitable for consumption. Regular TDS monitoring helps protect RO membranes , prevents scaling , and maintains consistent water quality.
A PH meter measures the acidity or alkalinity of water. Readings below 7 indicate acidic water , 7 is neutral , and above 7 is alkaline. Industries such as wastewater treatment , aquaculture , food processing , and chemical manufacturing rely on PH meters because water chemistry directly impacts product quality , regulatory compliance , and equipment life. Industrial grade PH meters often include advanced features such as Automatic Temperature Compensation ( ATC ) for more precise results.
Domestic meters are usually budget friendly and portable but limited in accuracy. Industrial TDS and PH meters are designed for heavy duty use , offering higher precision , stronger build quality , and additional features like waterproofing , data logging , and multi parameter functions. Many industrial devices can measure TDS , PH , Electrical Conductivity ( EC ) , and Temperature in a single unit , making them versatile for continuous monitoring.
Romegamart offers a wide range of industrial meters. Popular choices include the OCEAN STAR Digital LCD TDS Meter , known for its affordability and precision; the ATC Digital PH Meter , which provides high accuracy across the full 0– 14 PH range; and the Ocean Star TDS + PH Combo Meter , which combines two functions in one device. For advanced applications , buyers often choose multi parameter meters like the Professional Series COM 360 , which measure PH , EC , TDS , and temperature simultaneously.
The price of industrial meters depends on their accuracy , build quality , and features. A basic digital TDS meter may cost between ₹800 and ₹1 ,500 , while combo devices measuring both TDS and PH are generally priced between ₹1 ,500 and ₹3 ,500. Multi parameter meters with advanced features like ATC and waterproofing typically range from ₹3 ,000 to ₹7 ,000 , while high end professional grade instruments can go beyond ₹10 ,000.
When selecting a TDS or PH meter , start by defining your purpose— whether it’ s drinking water testing , industrial process monitoring , or laboratory use. For drinking water , a low range digital TDS meter is sufficient , while industrial applications may require multi parameter waterproof devices. Consider the accuracy , ease of calibration , and durability before purchasing. It is also advisable to choose trusted brands that provide warranty and after sales support , as this ensures reliability and long term performance.

Q1. What does a TDS meter measure ?
A TDS meter measures the concentration of dissolved salts , minerals , and impurities in water , expressed in parts per million ( ppm ).
Q2. What is the ideal TDS level for drinking water ?
Water between 0– 50 ppm is considered pure and safe for drinking. For industrial use , up to 150 ppm is generally acceptable.
Q3. What PH range should an industrial PH meter cover ?
A full range of 0 to 14 is ideal , as it covers both acidic and alkaline water testing.
Q4. Are TDS and PH combo meters authentic ?
Yes , especially models with Automatic Temperature Compensation and from reputed brands like Ocean Star.
Q5. How much does an industrial TDS meter cost in India ?
Depending on features , industrial grade meters range from accross ₹3 ,000 to over ₹10 ,000.
Accurate monitoring of water quality is essential for safe operations in industries and for ensuring pure drinking water. Industrial TDS and PH meters provide authentic readings that help businesses maintain compliance , protect equipment , and ensure consistent output.
