VIVOSUN pH & TDS Meter Combo - Simple, Accurate Water Testing
The Vivosun pH & TDS Meter Combo gives you two essential tools in one pack. Quickly check the pH of your nutrient solution and measure its TDS/EC levels to ensure plants are getting exactly what they need. Easy to use, pocket-sized, and accurate — it’s a must-have for any grower running coco, hydroponics, or soil with liquid feeds.
Please Note: These are purchased to order so slightly longer lead-times apply
Key Benefits
- 2-in-1 combo pack — includes a digital pH meter and a TDS/EC meter.
- Accurate readings — know your nutrient strength and acidity in seconds.
- Simple calibration — easy to reset for reliable, consistent results.
- Portable design — pocket-sized testers that can be carried anywhere.
- Clear LCD display — quick, easy-to-read results for fast adjustments.
- Essential for growers — avoid overfeeding, lockout, and pH-related issues.
Why You Need to Monitor pH & TDS
Plants can only absorb nutrients properly when the pH is in the right range. Too high or too low, and you risk nutrient lockout — meaning deficiencies even when food is present. At the same time, knowing your TDS/EC prevents overfeeding (which burns roots) or underfeeding (which slows growth). The Vivosun combo makes it quick and simple to dial in your water before every feed.
How to Use the VIVOSUN pH & TDS Meter Combo
- Prepare solution: Mix your nutrients in water as normal.
- Test pH: Switch on the pH meter, dip into solution, wait for reading, and adjust with pH Up/Down as needed.
- Test TDS/EC: Rinse the TDS meter probe, place in the same solution, and note the ppm/EC reading.
- Rinse & store: After use, rinse probes with clean water and cap to protect sensors.
