Product Information

The pH pen has a1-yearwarranty so if you encounter any issues with your current unit, please feel free to reach out to us for support. What is KCl Storage Solution?

Bluelab are renowned for producing the most accurate and reliable measuring devices. Contained within the Bluelab pH Pen is a unique probe. This probe measures both the temperature and the pH of a liquid. It is important to note , if the temperature of the solution is too high or low the accuracy of some pH readers can be negatively affected. 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 information is shown on the LCD display and with this vital information, you can now adjust the pH levels of your water with confidence. Accuracy in a pH meter is crucial because even a slight deviation from the true pH can impact your plants’ health. For instance, nutrient availability for plants is significantly affected by soil pH. If your pH readings are off, you might adjust your soil incorrectly, leading to nutrient deficiencies or toxicities. The Bluelab pH Meter is lauded for its precise measurements. It is a tool of choice for professional gardeners and commercial growers who require the highest level of accuracy. This meter usually provides readings with an accuracy of ±0.1 pH units, which is quite impressive. Use the Bluelab pH Pen is very simple. Just turn on the meter, dip the probe into you nutrient solution and wait for the reading to stabilise on the screen. You can 'hold' the reading by pressing on/off/hold button once. The unit will automatically turn off after a short while to preserve battery. You can press the 'Units' button to switch between F and C as your measurement choice of temperature. When using mineral-based nutrients and additives, the nutrients are provided to plants in their ionic form, and the pH level of the solution directly affects the availability of these ions. At the right pH level, nutritional ions are in forms that plants can readily uptake. Deviating from the optimal pH can result in nutrient deficiencies or imbalances, as certain ions become less available for absorption.

Get your nutrient temperature right to fight root diseases, improve growth and boost nutrient uptake further. Bluelab pH Pen User Manual - English - Spanish - German Deutsch - Dutch - Latin American Spanish - Canadian French Low ionic strength solutions, like distilled, deionized and reverse osmosis water cannot be measured with Bluelab pH Pens or probes. The reading will be unreliable because the pH-sensitive glass needs lots of ions to provide an accurate and reproducible reading. You will notice that readings will be erratic, and if you take multiple readings of the same solution they will differ each time. Any contamination on the glass membrane can also greatly affect the reading. We recommend using "lab grade" pH probes, these are pH probes that are usually refillable, and are shielded from electrostatic interference if you wish to measure the pH of pure water. When growing in hydroponic systems, the very first thing that I spend money on is a pH meter. I’ve used pH testing strips in the past as well as the liquid solution. However, neither of them worked very well for me as far as reliability.

Keep the glassware of the probe clean. Calibrate daily using high quality calibration solutions and calibrate to three points. Rinse the probe in DI water between uses and during calibration.Use pH probes that are refillable and are shielded from electrostatic interference. These can be expensive and require daily maintenance but they are specifically designed for the measurement of pure water.

Durability: Made with high-quality materials, this pH meter is designed for longevity. It can endure heavy use, making it a cost-effective investment in the long run.

Soak probe in KCl storage solution for 24 hours and retest. Don't measure proteins or oils with the pH pen. Soak probe in KCl storage solution for 24 hours and retest. Don't measure proteins or oils with the pH pen. You may need to replace the pH pen. Add a very small amount of high purity KCl or calcium magnesium (calmag) to the sample which will improve reliability and accuracy of the pH measurement because the ionic strength will be greater. Take your first measurement. Submerge the probe in your nutrient reservoir to view the readings on the display. Read this guide for correct usage.

Hydrate your Bluelab pH Pen. 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. Waterproof: This pen is fully waterproof, allowing for direct immersion in the soil or water without damaging the device. This is a critical feature when measuring pH in wet or damp environments. With proper care, the Bluelab pH Pen will last quite a long time. As with any electronic pH meter, you need to be extra careful in how you store and care for the pen if you want it to last for a while. Reading the Result: Once the probe is inserted into the soil, give the meter a few moments to provide a reading. The pH level will be displayed on the digital screen. Auto-Off Function: To conserve battery life, the Bluelab pH Pen comes equipped with an auto-off feature. The device automatically turns off after a period of inactivity, ensuring the longevity of the battery.

One of the defining factors of a quality pH meter is its level of accuracy. The Bluelab pH Meter, a professional-grade tool, is renowned for its precision. In this article, we’ll compare its accuracy to that of budget pH meters. Testing the Soil: Remove the protective cap from the probe. Insert the probe into the soil to the appropriate depth – usually about 2-4 inches or as per the product manual. It’s best to test multiple locations to get an average reading. It could be the fact that I’m partially colorblind, but I felt that basing my plant’s health off of what shade of “orangish yellowy red” my pH vial or strip was showing me was probably not a good idea in the long run, especially if I wanted to get serious about the quality of my grows.
