EC & pH Meters

27 products

Showing 1 - 27 of 27 products

Our EC & pH Meters collection curates rock-solid gear from Bluelab, Hanna and Milwaukee, giving you lab-grade accuracy that stands up to steamy tents and dusty veggie patches.

Accurate readings matter: keeping your nutrient solution at an EC between 1.2–2.5 mS cm-¹ and a pH in the proper zone unlocks maximum nutrient uptake. Grab an ec meter for conductivity, a slim ph pen for quick daily checks, or a combo ph meter that does both in one pocket-friendly tool. Pair your new meter with our pH adjusters and buffers to lock in the sweet spot, or explore our nutrient starter kits for a complete feed program. Order today and enjoy rapid nationwide dispatch plus real humans on the phone if you need help.
