Bluelab pH Pen Plus

Introducing Bluelab pH Pen Plus - the next generation solution for growers who demand accuracy, durability and long-term value. This digital pH tester gives you lightning-fast and reliable results, whether you're measuring the pH of nutrient solution, soil or water. The fully replaceable probe makes it a smart investment that will save you costs in the future.

The correct pH value is crucial for the ability of your plants such as tomatoes, chillies or herbs to take up nutrients. With this pen, you can be sure that you are providing them with optimal conditions for healthy growth and a bountiful harvest.

Key features and benefits for growers

• Fully replaceable probe (REPHPLUS): you don't have to buy a whole new unit. Once the probe has reached the end of its life, simply replace it with a new one and continue measuring. This significantly reduces long-term operating costs.
• Probe with double junction technology: Ensures longer life and more reliable measurements by minimizing the risk of contamination and probe clogging. Your results will be more consistent and accurate.
• Fully waterproof and dustproof (IP68): This pH meter is built for the harsh conditions of growing spaces. Accidental immersion in a nutrient tank won't damage it, plus it floats on the surface so it's easy to find.
• Backlit LCD display: The large, clear display makes it easy to read pH and temperature readings in any lighting conditions, even in a dark grow tent.
• Easy two-point calibration with reminder: Calibration to pH 7.0 and 4.0/10.0 is quick and intuitive. In addition, after 30 days, the instrument itself will remind you to recalibrate so that your measurements are always accurate.
• Automatic Temperature Compensation (ATC). This tester automatically compensates for temperature differences, ensuring you always get an accurate result regardless of conditions.
• "Hold" function. This comes in handy when you are measuring in hard-to-reach places and need to write down the result in peace.
• Auto shut-off: For maximum battery saving, the device switches itself off after 4 minutes of inactivity.
• The protective cap contains a sponge infused with KCI solution to keep the sensitiveprobe constantly hydrated. This ensures that the pen is always ready for immediate and accurate measurement.
