EC Meter
Water Quality
An EC meter measures nutrient strength so growers can mix feed accurately and spot dilution or concentration problems early.
Usage Instructions
- Measure after mixing nutrients and again after top-ups so the trend is clear.
Troubleshooting
EC rises faster than expected
Check for evaporation, salt buildup, and missed reservoir top-ups.
Maintenance
- Keep the sensor clean and confirm accuracy with calibration fluid.
Make It Yourself
- Create a feed log that records EC, pH, temperature, and crop stage together.
Cost
- 30 - 260 NZD
Power Consumption
- 1 - 2 battery
Variants
- TDS/EC combo pen: Good for home growers checking mixed nutrient tanks.
- Inline monitor: Provides constant readings in recirculating systems.
