Compatibility With Bluelab Products

The pH probe is compatible with a range of Bluelab devices, including the Bluelab Guardian Monitor, Combo Meter, and pH Controller. It can be used as a replacement or spare probe for these devices, ensuring accurate pH monitoring in your hydroponic system.


BNC Connector

The probe is equipped with a BNC connector, which allows for easy and universal connection with compatible Bluelab devices. This connector makes it convenient to use the pH probe interchangeably with different Bluelab products.


Waterproof Design

The pH probe is fully waterproof, making it safe to submerge in water and allowing for reliable pH measurements in hydroponic solutions. This feature also simplifies the cleaning process, as the probe can be easily wiped down with a damp cloth.


Long Lasting Double Junction Design

The pH probe features a double-junction design for increased longevity. It consists of two chambers, each with a wire inside. The second chamber contains an additional salt bridge, which helps prevent contamination and reactions between the electrode fill solution and the solution being measured. With proper care and maintenance, the Bluelab pH probe can last for approximately 12 months.


Care Instructions

To prolong the life of the pH probe, it is recommended to keep it wet at all times when in use. When not in use, place the protective storage cap over the probe and regularly top up the potassium chloride (KCl) solution inside the cap.

The Bluelab pH Probe offers several advantages, including quick and accurate pH measurement results, a 2-meter cable for easy reach in larger spaces, a durable polycarbonate housing, and effective performance in solutions with an electrical conductivity (EC) of 0.2 and above.


With the Bluelab pH Probe, you can ensure precise pH monitoring and maintain optimal conditions for your plants in hydroponic systems. Its compatibility, waterproof design, and long-lasting performance make it a reliable tool for your pH measurement needs.
