Replaceable probe design for long-term use: The Bluelab pH PenPlus features a replaceable pH and temperature probe so when natural probe wear occurs, you can simply replace the probe instead of the entire pen. This helps reduce downtime and keeps your meter ready for continued use.
Accurate pH and temperature measurement: Measure both pH and temperature to help monitor nutrient solutions and maintain optimal conditions for hydroponics, soil growing, aquariums, brewing, and other water testing applications.
Designed for demanding grow environments: Built with an IP68 dust- and waterproof rating, the pH PenPlus is designed for wet grow rooms, mixing tanks, and daily use around nutrient solutions.
Simple calibration with clear backlit display: The handheld pH meter features a bright backlit display for easy reading and a simple two-point calibration process. A 30-day calibration reminder helps maintain consistent measurement accuracy.
Complete kit with trusted Bluelab quality: Includes pH 7.0 and pH 4.0 calibration solution sachets and KCl storage solution to help maintain probe hydration and performance. Designed in New Zealand and backed by a 2-year limited warranty for the pen and 6-month warranty for the replaceable probe.
