Bluelab pH Pen​ - The ultimate handy solution for measuring pH                                                
Perfect for quick and easy pH and temperature readings direct from your solution.
The Bluelab® pH Pen is the preferred option for hand held pH meters.  It provides a compact, quick and handy way to manage the success of your crops to ensure maximum uptake of nutrients.
A key parameter that affects nutrient uptake is whether your solution is acid or alkaline. We measure this in pH.
Teamed with our Bluelab® Conductivity Pen you have a robust, convenient and accurate measurement system.

Why measure pH and temperature? - Get the fundamentals of growing right, every time

Healthy growing plants, just like humans, need a balanced diet of appropriate nutrients (food). However, plants can only access these nutrients when the nutrient solution is within a certain pH range.
From a water chemistry perspective, pH (potential Hydrogen) plays a pivotal role in making the nutrients in your solution soluble so that they can be accessed by your plants. That’s why if your growing solution becomes too acidic or too alkaline, the plants won’t be able to get access to the nutrients they need to grow. The temperature of your growing solution is equally important as having a solution that’s too hot or too cold can affect growth rate and structure.
To help your plants thrive, get the fundamentals right by measuring pH and temperature to ensure that these are always in the optimal range.

Combine it with the Bluelab Conductivity Pen to Create the ultimate Grower’s Toolbox.
Conductivity and pH are connected. When preparing a new nutrient solution, you'll need to add the appropriate amount of nutrients according to the plants' needs. Once you’ve checked the conductivity (EC or PPM), which confirms whether the nutrient levels are correct, you'll then need to regularly adjust the pH to ensure those nutrients are available to the plant.
After all, nutrients are expensive so it’s important that you always optimise them.
With Bluelab’s Conductivity Pen, you can take measurements of your nutrient solution to ensure that your plants truly flourish.
