Bluelab pH Probe - Replace the pH probe rather than the whole Bluelab® Meter
The Bluelab® pH Probe is a replacement pH probe suitable for use with Bluelab® products that use a BNC fitting.
pH probes have a limited lifespan, they age with everyday use. With proper care and use (keeping the probe tip hydrated and cleaning once a month) you can extend the probe life.
The pH probe tip should be stored in KCl solution to minimise the contamination of the gel.

Why measure pH? - Understand the science behind healthy plants
Just like humans, all growing plants need a balanced diet of nutrients (food) in order to thrive. However, your plants will only be able to access these nutrients if the nutrient solution is within a particular pH range. 
From a water chemistry perspective, pH (potential Hydrogen) plays a critical role in making nutrients soluble so that they can be absorbed by your plants. When you’re growing solution becomes too acidic or too alkaline, your plants won’t be able to access the nutrients they need to grow.  
Get the fundamentals of growing right by regularly measuring pH to ensure that this is always within the optimal range. 
Durable and affordable probe technology for accurate and quick pH measurements
The durable Bluelab pH Probe has been designed with longevity in mind, with a double-junction probe, polycarbonate housing and high-quality electrical components.  
Created with advanced and affordable technology, you can rely on Bluelab’s pH Probe to give you accurate and fast measurements every single time.  
All our products are designed with growers, for growers – so you can be confident that the Bluelab pH Probe will help you carry out the essential tasks of everyday growing with ease. This fully waterproof product can even be left inside your reservoir for continual monitoring or spot checking. 
Extend the life of your pH probe with Bluelab pH Probe maintenance
You need to regularly clean and maintain your Bluelab pH Probe to ensure its ongoing accuracy and longevity.
Use Bluelab’s Probe Care Kit, which contains everything you need to clean and care for your pH probe. Every time you clean your probe, calibrate it using Bluelab Calibration Solutions. 
In addition, boost your probe’s lifespan by ensuring that its tip stays wet at all times. Use the included storage cap whenever you’re not using your probe and regularly top up the amount of KCl inside the cap. 
This probe is compatible with all Bluelab products with a corresponding BNC connector, such as the Combo Meter and Guardian Monitor.
