Bluelab Combo Meter Plus - Measures pH, Conductivity, and Temperature

Root-Zone pH Measurement Across Soil, Coco Coir, and Rockwool

Preparing a pH slurry for every substrate check adds time that most growing schedules cannot spare. The Bluelab Combo Meter Plus swaps in the Bluelab Leap pH probe, whose toughened spear-tip takes a direct pH reading in soil, coco coir, rockwool, and potting mixes without any slurry or extraction step, while still measuring conductivity and temperature from the same handheld unit.

The Leap probe is detachable and can be replaced separately when it wears out, and the meter runs on two included AAA batteries for use anywhere in the facility.

Key Features & Benefits

• Bluelab Leap pH probe included — toughened spear-tip for direct, fast pH measurement in any substrate.
• No slurry preparation needed — measure pH directly in soil, coco coir, rockwool, and potting mixes.
• Measures pH, conductivity, and temperature — all three parameters from one portable, battery-powered device.
• Detachable, replaceable probe — swap in a new Leap probe when the current one wears out.
• Backlit LCD with 30-day calibration indicator — readable in low light and keeps calibration on schedule.

Who Should Use This

Growers working across soil, coco, rockwool, and hydroponic solution who need fast, direct root-zone pH readings without the extra step of preparing a slurry are the direct fit for this meter.

Frequently Asked Questions

How is this different from the standard Combo Meter?

The Combo Meter Plus includes the Bluelab Leap pH probe, which uses a toughened spear-tip for direct measurement in soil, coco coir, rockwool, and other substrates without preparing a slurry. The standard Combo Meter uses a liquid-focused double-junction probe instead.

Does this meter need an external power supply?

No, it runs on two included AAA alkaline batteries for full portability. No external power source is required.

Can the Leap probe be replaced?

Yes, the probe is detachable and can be replaced with a compatible Bluelab Leap pH probe when it reaches the end of its service life. Replacing just the probe restores full accuracy without buying a new meter body.

What media types can this meter measure?

With the Leap probe, it measures directly in soil, coco coir, rockwool, potting mixes, and nutrient solution. This makes it suited to operations running more than one media type.
