Standard pH pens are built for solution, not substrate — pushing one into soil or coco risks damage and gives you a slow, unreliable read. The Bluelab Soil pH Meter solves this with a toughened speartip probe designed for direct insertion into growing media, delivering fast, precise pH readings straight from the root zone in hydroponics, soil, and coco coir alike.
The replaceable Soil pH Probe drives accuracy across media types, and simple 2-point calibration with a built-in 30-day reminder keeps readings dependable over time. A KCl-filled probe cap keeps the probe hydrated between uses, and a 2-metre (6.6ft) cable reaches into hard-to-access containers and beds.
A bright backlit display and compact handheld design make it easy to check root-zone pH anywhere in the grow room, and the meter's multimedia-friendly build means it moves seamlessly between different growing environments without needing a different tool for each one.
