- Reads temperature in °C or °F
- Measures conductivity in EC, CF, ppm 500 (TDS), or ppm 700
- Conductivity probe is factory-calibrated and ready to use immediately
- KCl-filled pH probe storage cap to keep the pH probe hydrated between uses
- 2 metre / 6.6 ft cables for measuring in hard-to-reach locations
- Automatic Temperature Compensation (ATC) for accurate readings across varying conditions
The Science Behind Healthier Plants
pH, EC, and temperature are the three fundamental parameters of plant nutrition. EC (Electrical Conductivity) indicates the total concentration of nutrients in your solution. pH (potential Hydrogen) determines how acidic or alkaline your medium is — which directly controls nutrient absorption. Temperature affects growth rate, dissolved oxygen levels, and overall plant structure.
By measuring all three simultaneously with the Bluelab Combo Meter, you get a complete picture of your nutrient solution's health in a single reading. Pair it with the Bluelab Leap pH Probe for direct root zone measurements via the BNC connection.
