Bluelab Multimedia pH Metre

Product detailed description

The Bluelab Multimedia pH Metre is a portable pH metre for growers who need to measure pH directly in substrate, coco, or rockwool – not just in solution. The replaceable Leap pH Probe with a reinforced tip reaches the root zone where pH truly determines nutrient uptake. The metre measures only pH (no EC).

Why it is worthwhile

• Replaceable Leap pH Probe with a reinforced tip for direct measurement in soil, coco, and rockwool, connected via BNC connector – when it wears out, you replace only the probe.
• Accuracy ±0.1 pH in the range 0.0–14.0 pH, temperature measurement (0–50 °C), and backlit display with low battery indicator.
• Two-metre long cable for convenient measurement in hard-to-reach places.
• Five-year warranty on the metre (6 months on the pH probe) and automatic shut-off after 4 minutes to save battery.

Calibration and probe care

Calibrate the metre with one button using two-point calibration solutions pH 4.0 and pH 7.0; after successful calibration, a pictogram lights up on the display, and when it goes off, it is time to recalibrate. The package includes the metre, Leap probe, dibber, and two sachets of calibration solution. Do not let the probe dry out; replacement Bluelab Leap pH Probe and care kit for pH probes are sold separately.

Which option to choose

Choose the Multimedia pH Metre when you measure pH directly in substrate and want a replaceable probe and cable for hard-to-reach places. A compact alternative for substrate is the Bluelab pH Pen for soil with an integrated probe. If you need to measure EC in solution as well, opt for the Bluelab Combo Metre.

Why measure pH in the root zone? That is where nutrient uptake is determined – roughly around 6.0–7.0 in soil, and rather 5.5–6.5 in coco. Verify the exact range according to the crop and used fertilisers.

Frequently asked questions

Does this device measure EC as well?

No, the Bluelab Multimedia pH Metre measures only pH and temperature, not conductivity (EC). It is designed for accurate pH measurement directly in substrate thanks to the robust Leap probe. If you need to measure EC as well, choose a combined device such as the Bluelab Combo Metre.

How does the Leap probe differ from a regular pH probe?

The Leap pH Probe has a reinforced tip designed for direct measurement in solid media – soil, coco, and rockwool. A regular glass probe is mainly intended for solution and would be easily damaged in substrate. The Leap probe is replaceable, so you can fit a new one after wear.

How do I know when it is time to calibrate?

After successful two-point calibration (pH 4.0 and 7.0), a calibration pictogram lights up on the display. When it goes off, it is time to recalibrate the metre. Regular calibration keeps measurements accurate – without it, values gradually drift.
