pH and is fully temperature compensated, so you can rely on getting accurate readings every single time. Portable, affordable and robust, our range of reliable Bluelab pH pens will give you quick and accurate pH and temperature measurements on the go.

The pen uses advanced technology to provide accurate and reliable pH readings, making it an essential tool for any grower looking to optimize their plant growth and yields. Whether you’re looking for replacement pH probes, pH probe care kits, pH calibration solutions or other accessories, we have the product that you’re looking for. When paired with the Bluelab EC or ppm Pen, it becomes a complete system for managing crops and maximising nutrient uptake. Fortunately the Bluelab pH Pen contains an onboard computer that uses temperature information to ensure precise accuracy of the pH reading at all times. The easy-to-follow calibration process will ensure that your pH measurements remain accurate; if you’re using your pH meter every day, it will need to be calibrated more regularly.

Conductivity (EC or PPM) is a fundamental measurement that will help you ensure that your plants are always getting the right amount of food. If the probe does dry out it must be soaked for 24 hours in the same way it is before first use (see above). pH, the pH Pen provides precise readings, allowing you to make informed adjustments to your nutrient solution. The Bluelab's pH Pen a 2-in-1 handheld pH meter is very handy to use and provides a compact, quick and better way to manage the success of crops. pH meters need to be calibrated regularly to maintain accurate readings of the acidity of your nutrient solution.

It provides a compact, quick and handy way to manage the success of crops, to ensure maximum uptake of nutrients. Tried and trusted by growers all over the world, this essential tool is one of our top-selling products. Calibration is essential to maintain accuracy over time, and the pH Pen simplifies this process, allowing you to calibrate quickly and confidently. The calibration sequence will now begin with '0' sequentially flashing across the screen, after '0000' stops flashing, pH7 is displayed and the sequence is complete.

The clear and easy-to-read interface allows for quick assessment of the pH level, enabling you to adjust your nutrient solution as needed. For crops that need monitoring 24/7, our wall-mounted monitors and pH controllers will measure your key parameters, including pH, and alert you when these measurements move out of their optimal 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.The hand held pH pen provides a compact quick and handy way to manage the success of your crop to ensure maximum uptake of nutrients. When growing, it’s easy to get caught up in the obvious big things: nutrient feeders/bottles, tent and extraction. Before first use, you must first hydrate the pH pen in KCl solution for 24 hours and then calibrate the pen using the calibration guide below. Teamed with the Bluelab EC Pen or Bluelab ppm Pen, it is a handy, convenient and accurate system for ensuring optimum plant growth and health.
