Fast and accurate pH measurements from the palm of your hand. Get fast, precise pH readings in various growing media, including hydroponics, soil, coco coir, rockwool, and potting mix. The durable spear-tip Leap Probe allows direct root-zone measurements, while simple two-point calibration ensures ongoing accuracy. Features Compact handheld design for convenient use in the grow room, greenhouse, or field Bright, easy-to-read backlit display Replaceable Bluelab Leap pH Probe with toughened spear-tip for direct measurements in soil, coco, rockwool, and solution Multimedia-friendly — accurate across a wide range of growing environments and substrates Simple 2-point pH calibration (pH 4.0 and pH 7.0) with a 30-day calibration reminder 0.1 pH resolution for precise readings KCl-filled probe cap to keep the pH probe hydrated between uses 2 metre / 6.6 ft cable for measuring in hard-to-reach locations Replacement Leap Probes and standard pH Probes available separately Measure pH in a Variety of Growing Media Combine the Bluelab Multimedia pH Meter with the Bluelab Leap pH Probe to take fast, accurate pH readings across nutrient solution, soil, coco coir, rockwool, potting mix, and many other media types. Because pH directly affects nutrient availability, keeping it in the correct range is essential for healthy plant growth and maximum yield. Calibration is simple with one push button on the meter and fresh Bluelab Calibration Solutions. A successful calibration indicator is displayed on screen; after 30 days, this will disappear and you'll need to recalibrate to ensure ongoing accuracy. Measure Root Zone pH for Healthier Plants The reinforced spear-tip Leap Probe measures pH directly in soil, substrate, and solution — durable and reliable for root zone measurements. Know your pH fast, so you can ensure optimal nutrient uptake and spot-check across your greenhouse or grow room with confidence.
