Digital pH & TDS Meter Combo – High-Accuracy Water Quality Tester for Aquarium, RO System & Lab Use

Ensure your water quality remains at its best with this premium Digital pH & TDS Meter Combo. Designed for both precision and ease-of-use, this kit combines a dedicated pH meter and a TDS/EC meter to deliver a complete water-quality testing solution — ideal for aquariums, reverse-osmosis (RO) systems, drinking-water monitoring, and laboratory use.

Why it stands out

• High-accuracy pH measurement across the full 0.0-14.0 pH scale, with precision around ±0.1 (or better), giving you reliable data for home, hobby or lab applications. Similar meters list comparable specs. 
• TDS (Total Dissolved Solids) & EC (Electrical Conductivity) meter covers a wide range (for example up to ~0-9 990 ppm for TDS and up to ~9 990 µS/cm for EC) enabling comprehensive water-analysis capability.
• Temperature detection included, often spanning from around 0 °C to 80 °C (32 °F to ~176 °F), which allows you to factor in thermal effects on readings and ensures better accuracy in varied conditions.
• Easy-to-read digital LCD screens on both meters — making fast readings effortless.
• Portable, all-in-one kit: Includes protective artificial-leather and plastic carrying case, making it convenient for on-site use and storage.
• Battery-powered (e.g., LR44 or CR2032) for long-lasting, ready-to-use performance in field, home or lab environments.

Key Features

• Accurate pH measurement: 0.0–14.0 pH scale, 
• TDS & EC measurement: 0–9999 ppm TDS and 0–9990 µS/cm EC (typical values).
• Temperature detection: e.g., 0.1 °C increments from ~0 °C to 80 °C.
• Clear digital display of results with fast stabilization time.
• Robust and portable design: meters housed in protective casing with carry case, suitable for aquariums, RO systems, drinking water, labs.
• Practical kit for hobbyists, aquarium owners, water filtration system users, lab technicians, educational settings.

Applications
Perfect for:

1. Aquariums & fish tanks — monitoring pH and dissolved solids for healthy aquatic life.
2. Reverse-osmosis (RO) / DI water filtration systems — verifying output water quality and purity.
3. Home tap water / drinking water monitoring — ensuring safe and clean water for families.
4. Industrial or commercial water-testing rigs — e.g., cooling towers, hydroponics, labs.
5. Travel or field water-safety checks — portable enough to carry along.
6. Science labs, educational projects or hobbyist experiments where water-quality tracking is needed.

How to Use

1. Remove protective cap from the meter.
2. Rinse electrode with distilled water and gently dry with filter paper.
3. Press the ON/OFF button to power the device.
4. Immerse the electrode into your sample solution (do not exceed the maximum immersion line) and stir gently.
5. Wait ~30 seconds (or until a stable reading appears) on the display.
6. After taking the reading, rinse the electrode with pure water, dry gently and turn the meter off.
7. Store the unit in its case when not in use to prolong its life.

Precautions & Care

• This meter is not fully waterproof — do not immerse the entire body in water or submerge beyond the designated immersion line.
• Avoid high-temperatures or direct sunlight for storage; extreme heat may damage electronics or degrade accuracy.
• Handle with care — avoid drops or heavy impacts, which can damage the sensor or calibration.
• Regular calibration is recommended (especially the pH unit) to maintain accuracy.

Why Choose This Combo?
Many water-quality testers offer only pH measurement or only TDS/EC measurement. This kit bridges both in one package — giving you full visibility into both acidity/alkalinity and dissolved-solid load. When you compare to references of similar meters, many list ±2 % or similar accuracy for TDS/EC and full-scale pH range. Flipkart+1 This makes our combo an excellent value-for-money choice for anyone needing reliable, everyday water-testing performance.
