Measure nutrient strength with a reliable Bluelab Conductivity Pen.

This handheld meter helps you check the strength of your nutrient water by measuring EC, CF, or ppm, along with water temperature. It is a useful tool for growers who want more confidence when topping up nutrients, refreshing the reservoir, or learning how their FlowGrow tower responds over time.

Ideal for home growers who want a more accurate way to understand nutrient strength beyond basic dosing instructions.
