Descripción
Bluelab pH PenPlus gives you fast, dependable pH and temperature readings with one major upgrade over a conventional pH pen: when the probe eventually wears, you can replace the probe rather than the whole meter.
Built for regular use around nutrient tanks and hydroponic systems, the PenPlus uses a double-junction pH probe, has a bright backlit display and is IP68 dustproof and waterproof. Two-point calibration and a 30-day calibration reminder make it straightforward to keep readings on track.

Keep it accurate
pH probes need regular cleaning, calibration and correct storage. We recommend keeping a Bluelab pH Probe Care Kit alongside the PenPlus. For routine calibration, use pH 4 and pH 7 Buffer Solution. Keep the probe hydrated between uses with KCl pH Probe Storage Solution. If you want pH and EC probe maintenance together, see the Bluelab pH & EC Probe Care Kit.
For growers who also want conductivity readings, pair it with the Bluelab EC Pen. If you would rather have pH, EC and temperature in a single handheld meter with app connectivity, see the Bluelab OnePen.
