TDS Meter Digital LCD Pen Tester

The TDS Meter Digital LCD Pen Tester is a portable, easy-to-use device designed to measure the Total Dissolved Solids (TDS) in water. TDS indicates the amount of dissolved substances like salts, minerals, and metals in water. This meter helps determine water purity and is commonly used in drinking water testing, hydroponics, aquariums, RO/DI systems, pools, and labs.

Key Features:

• Digital LCD Display: Clear and easy-to-read screen shows TDS values in parts per million (ppm).

• Auto Shut-off: Saves battery by turning off automatically after a few minutes of inactivity.

• Hold Function: Locks the reading on the display for easy recording.

• Measurement Range: Typically 0–9999 ppm.

• Accuracy: ±2% for reliable results.

• Battery Operated: Runs on standard LR44 or similar button cell batteries.

• Compact & Lightweight: Pen-style design makes it convenient to carry in your pocket or tool kit.

How to Use:

1. Remove the protective cap.

2. Turn on the meter using the power button.

3. Dip the meter into the water up to the maximum immersion level.

4. Wait a few seconds for the reading to stabilize.

5. Read the TDS value on the screen.

6. Press "Hold" if you want to lock the reading.

Applications:

• Testing drinking water quality

• Monitoring RO/DI systems

• Aquarium and hydroponics maintenance

• Water purification processes

• Educational experiments
