The science behind healthier plants

While EC (Electrical Conductivity) indicates the total amount of nutrients in your solution, pH (potential Hydrogen) shows how acidic or alkaline your medium is, which determines nutrient absorption. Temperature affects your plants’ growth rate and structure.

The fundamental parameters of pH, conductivity and temperature all play a pivotal role in driving optimal plant health. By regularly measuring the fundamentals, the Bluelab Combo Meter will enable you to optimise your plants’ nutrient uptake.

Bluelab Combo Meter is the 3-in-1 pH, EC & temp meter trusted by growers for over 25 years

It provides everything you need to ensure your plants thrive, with individual probes for lasting value. 

The Bluelab Combo Meter measures pH, conductivity and temperature in nutrient reservoirs, run-off and water supply. What’s more, this meter can be used on the go, giving you fast and accurate readings when and where you need them.

Brilliantly simple design

The Bluelab Combo Meter provides the ultimate convenience by taking care of all three nutrient uptake fundamentals simultaneously.

Not only that, but this multi-parameter meter and its probes feature a brilliantly simple design. The Bluelab pH Probe is easy to use, clean and calibrate; when the time comes, it’s also easy to replace. Likewise, the Bluelab Conductivity Probe has straightforward functionality, requiring no further calibration.

Pair the Bluelab Combo Meter with the Leap pH Probe for direct root zone measurements via the BNC connection.
