Description
Pocket TDS Meter Portable Digital Tester Pen for Drinking water, RO DI Filters.
Ensure the purity of your water with this Digital TDS Meter Water Quality Tester. Designed for fast, reliable measurement of Total Dissolved Solids (TDS) in a wide range of water sources. Using advanced microprocessor technology and a premium titanium alloy probe, this tester delivers ±2% accurate readings within seconds. The built-in Automatic Temperature Compensation (ATC) automatically adjusts measurements based on water temperature, ensuring precise results in different environments.
With a 0-999 ppm measurement range, this compact water testing pen is ideal for drinking water, tap water, RO DI filtration systems, aquariums, hydroponics, pools, and spas. The easy-to-read LCD screen displays results in just 5 seconds, allowing you to quickly assess water quality and determine when to replace filters.
Designed for convenience, the tester features one button operation, a HOLD function for stable readings, and automatic power-off after 5 minutes to extend battery life. Powered by 2 LR44 batteries (included), it can last over two years with normal use. Lightweight and portable, this TDS meter is a practical tool for maintaining better water quality at home or on the go.
TDS Meter User Manual
1. Remove the protective cap from the probe of the TDS meter.
2. Turn on the meter. Press the ON/OFF button to switch the TDS meter on.
3. Immerse the probe into the water sample up to the maximum immersion level (approximately 2 inches / 5 cm).
4. Wait for the reading to stabilize. The TDS meter automatically compensates for temperature variations using Automatic Temperature Compensation (ATC). The reading typically stabilizes within 30-45 seconds. Once the reading is stable, press the HOLD button to save the measurement.
5. After use remove the meter from the water. Shake off excess water from the probe or wipe it gently with a soft tissue. Press the ON/OFF button to switch the TDS meter off.
6. Replace the protective cap.
