Bluelab pH & Conductivity Pen Starter Kit
The Bluelab pH & Conductivity Pen Starter Kit is a portable measurement bundle designed to provide essential solution monitoring for hydroponic and nutrient-based systems. It combines the Bluelab pH Pen and Bluelab Conductivity Pen with calibration and maintenance solutions, allowing for immediate setup and ongoing care of both instruments.
The pH Pen measures solution acidity or alkalinity, while the Conductivity Pen measures nutrient strength in conductivity units, supporting accurate assessment of nutrient concentration. Together, they provide a practical handheld solution for routine testing of reservoirs, feed solutions, and runoff.
This starter kit includes the required calibration solutions and storage solution to maintain probe accuracy over time. Both pens are designed for direct immersion testing and feature digital displays for clear readings, making them suitable for regular monitoring in grow systems where consistent pH and nutrient levels are required.
