The Bluelab Leap pH Probe is a reinforced, multi-environment pH probe designed for direct measurement in soil, substrate, and nutrient solutions. It connects to compatible Bluelab handheld meters, monitors, and controllers via a standard BNC connection, enabling accurate pH readings across both media and liquid applications.
Engineered with Bluelab’s Leap™ technology, the probe is built to support consistent performance in demanding growing environments. Its reinforced spear tip allows direct insertion into soil and substrates for in-situ root zone measurement, while the same probe can also be used for continuous monitoring in nutrient reservoirs.
The probe features a double-junction design to support reliable readings in a range of solution conditions and is fully waterproof for use in wet environments. It is supplied with a KCl-filled storage cap to maintain probe condition and ensure readiness between uses.
