Bluelab Leap pH Probe - for Combo Meter - Combo Meter Plus - and Multimedia pH Meter

Direct Substrate pH Probe for Any Growing Medium

Preparing a slurry to check root-zone pH adds a step that a busy grow schedule rarely has room for. The Bluelab Leap pH Probe skips that step entirely, using a reinforced spear-tip to take direct pH readings in soil, coco coir blends, rockwool, potting mixes, and nutrient solution.

The probe uses a double-junction design to reduce reference contamination and extend service life, and a protective BNC connector cap guards against corrosion during storage. It is compatible with the Bluelab Combo Meter, Combo Meter Plus, and Multimedia pH Meter.

Key Features & Benefits

• Reinforced spear-tip — penetrates soil, coco, rockwool, and potting mixes for immediate readings, no slurry needed.
• Double-junction design — reduces reference contamination for extended probe life.
• Fast sensor response — quick, accurate results for efficient monitoring across multiple growing zones.
• Protective BNC connector cap — prevents corrosion during storage.
• Compatible with three meter models — fits the Combo Meter, Combo Meter Plus, and Multimedia pH Meter.

Who Should Use This

Growers working across multiple growing media who need fast root-zone pH data without slurry preparation, and who own a compatible Bluelab meter, are the direct fit for this probe.

Frequently Asked Questions

Which Bluelab meters is this probe compatible with?

The Leap pH Probe is compatible with the Bluelab Combo Meter, Combo Meter Plus, and Multimedia pH Meter. It is not designed for pen-style meters.

Can this probe measure pH directly in rockwool?

Yes, the reinforced spear-tip allows direct measurement in rockwool, soil, coco coir, potting mixes, and nutrient solution without any slurry preparation. Simply insert the tip and read.

Why does the double-junction design matter?

The second junction acts as a buffer that keeps the reference cell cleaner for longer than a single-junction probe. That translates into a longer working life and steadier readings across repeated substrate insertions.

How does the BNC connector cap help?

The cap covers the BNC connector during storage to prevent corrosion. Keeping the connector clean maintains a reliable electrical connection when the probe is reinstalled.
