TDS Meter Pen – Digital Water Quality Tester for Drinking Water, RO Water Filter in Pakistan

The TDS Meter Pen is a compact and reliable digital water quality testing device designed to measure Total Dissolved Solids (TDS) in drinking water. It is widely used in homes, laboratories, aquariums, and water filtration systems across Pakistan to help ensure safe and clean water consumption.

Clean drinking water is essential for good health, but water can contain invisible contaminants such as dissolved salts, minerals, and harmful substances. A TDS meter pen helps users quickly check water quality by measuring impurities present in parts per million (ppm). Even if water looks clear, it may still contain unwanted dissolved solids, making regular water testing important.

Key Features of TDS Meter Pen

Measures TDS levels from 0 to 9990 ppm, making it suitable for testing various water sources including tap water, filtered water, and bottled water.

High Accuracy Performance
Uses advanced microprocessor technology to deliver approximately ±2% accuracy, providing dependable results for daily water quality monitoring.

Dual Resolution Display

• 1 ppm resolution for 0–999 ppm readings

• 10 ppm resolution for 1000–9990 ppm readings

This allows users to monitor water quality with better precision.

Digital LCD Screen
The clear display provides instant and easy-to-read TDS values.

Temperature Measurement (Selected Models)
Some versions include temperature sensing functionality for additional water quality analysis.

Automatic Power Saving
The device automatically turns off after about 10 minutes of inactivity, helping extend battery life.
