Our best-selling meter paired with the Leap pH Probe for quicker measurements in any substrate.

Take care of the fundamentals - Three-in-one portable solution

The fundamental parameters of pH, conductivity and temperature all play a pivotal role in driving optimal nutrient uptake. With Bluelab’s Combo Meter Plus, you can measure all these fundamentals in one convenient, portable device.

While 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 Bluelab Combo Meter Plus measures pH, conductivity and temperature in substrates, 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.
