Bluelab Soil pH Probe - 2m / 6.6ft Cable

Standard solution probes aren't built to handle direct insertion into soil or substrate — pushing one into growing media risks damage and gives you a slow, unreliable read. The Bluelab Soil pH Probe solves this with a reinforced spear tip designed for direct measurement in soil, substrate, and solution alike, without needing a separate probe for each environment.

Built around the same dependable double-junction technology as Bluelab standard solution pH probes, it connects via a standard BNC connector, making it compatible with any Bluelab handheld meter, monitor, or controller that uses BNC — including as a replacement probe for the Bluelab Combo Meter with Soil pH Probe and the Bluelab Soil pH Meter. A 2-metre (6.6ft) cable and fully waterproof construction round out a build made for daily use across multiple growing media.

A KCl-filled storage cap keeps the probe hydrated between uses, helping protect the reinforced tip and extend its working life whether you're testing a reservoir, a coco slab, or straight into soil.
