Full product description
The Bluelab pH PenPlus is a premium handheld pH and temperature meter designed for growers who want fast, reliable readings without replacing the entire meter when the pH probe eventually wears out.
Unlike a traditional disposable-style pH pen, the pH PenPlus features a replaceable double-junction pH and temperature probe. When normal probe wear occurs, simply replace the probe and keep using the pen. This helps extend the useful life of the meter and reduces downtime.
Built to an IP68 waterproof and dustproof rating, the Bluelab pH PenPlus is designed for regular use around hydroponic reservoirs, nutrient tanks and grow rooms. Its compact handheld design, bright backlit display and simple calibration system make checking your nutrient solution quick and straightforward.
Accurate pH management is essential for nutrient availability. Keeping your solution within the correct pH range helps plants access the nutrients they need for healthy growth.
Why Choose the Bluelab pH PenPlus?
The major advantage of the PenPlus is its replaceable probe. Instead of replacing the complete pH meter once the sensing probe reaches the end of its working life, the probe can be swapped for a new one.
It is an excellent choice for home growers and commercial growers wanting a durable, serviceable pH meter for regular nutrient-management tasks.
