Bluelab's best-selling meter paired with the Bluelab Leap pH Probe for faster measurements in any substrate.
The Bluelab Combo Meter with Leap pH Probe measures pH, conductivity (EC), and temperature in substrates, nutrient reservoirs, run-off, and water supply. Portable and battery-powered, it delivers fast, accurate readings when and where you need them — in the grow room, greenhouse, or field.
Features
- Measures pH, conductivity (EC), and temperature simultaneously on the go
- Brilliantly simple design — easy to use, clean, and calibrate
- Backlit display for clear readings in any lighting condition
- Bluelab Leap pH Probe with reinforced spear-tip — safely stored and ready to measure straight away in soil, coco, rockwool, and solution
- Calibration-free conductivity probe — factory-calibrated and ready to use immediately
- 2-metre / 6.6 ft cable for measuring in hard-to-reach locations
- Automatic Temperature Compensation (ATC) for accurate readings across varying conditions
- Customisable scales — conductivity in EC, CF, ppm 500 (TDS), or ppm 700; temperature in °C or °F
- Simple 2-point pH calibration with a 30-day calibration reminder
- KCl-filled storage cap to keep the Leap Probe hydrated between uses
Three-in-One Portable Solution
This meter takes everything you love about the Bluelab Combo Meter and combines it with Bluelab's toughest probe — the Leap pH Probe. The advanced spear-tip probe technology delivers ultra-fast pH measurements directly from the root zone or in solution, helping you unlock your plants' full potential.
pH, conductivity, and temperature all play a pivotal role in driving optimal nutrient uptake. EC indicates the total amount of nutrients in your solution; pH shows how acidic or alkaline your medium is, which determines nutrient absorption; temperature affects growth rate and plant structure. Measure all three fundamentals in one convenient, portable device.
Optimise Your Root Zone
The Leap Probe's reinforced spear tip allows direct insertion into soil, coco coir, rockwool, and other substrates — giving you root zone pH data that a standard probe simply can't provide. Replacement Leap Probes are available separately, ensuring long-term reliability.
