Frequently Asked Questions

1. What is the difference between TDS and PPM?

TDS stands for ‘Total Dissolved Solids,’ which is a parameter used to measure water impurities. The unit for measurement of TDS is PPM (Parts Per Million).

2. How to calibrate the TDS meter?

Distilled water has 0 ppm, which may be an ideal medium for calibrating TDS meters.

3. What is the safe TDS level for water?

The recommended limit of TDS level in water or any liquid is 300mg/L. The WHO believes that TDS higher than 1200mg/L is not consumable.

With the best TDS meters by your side, you can ensure that every sip of water you consume is of good quality. These innovative devices are designed to measure water quality accurately and let users know if the water contains an appropriate amount of electrolytes, nutrients, and minerals. But before choosing the ideal product, ensure it is a pre-calibrated TDS meter for accurate readings, comes with an automatic shutdown function for long-lasting use, and has the latest microprocessor technology embedded in it, which helps achieve reliable performance.
