Bluelab PENPH pH Pen Fully Waterproof Pocket Tester, Easy Calibration, Double Junction Probe for Improved Accuracy and Durability, White

Product Information

Why is my pH reading drifting? Why your pH reading may not be stabilizing, and what this has to do with ionic content, or ionic strength. The Bluelab pH Pen is an advanced tool designed to provide precise soil pH readings. This portable, hand-held device offers a range of features that make it a favourite among commercial growers. Let’s delve into the key features of the Bluelab pH Pen.

This step was so unbelievably easy I actually was able to do it in the hydroponics shop! I ended up purchasing the Bluelab calibration kit just so I would be able to do it at home as well. To calibrate, the steps are pretty simple: 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.

This is a big no-no as it will mess with the calibration, potentially to the point where you need to get a replacement tip or – if you REALLY neglect the pen – you may need to get an entirely new one. 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. Gently brush around the glassware with a few drops of Bluelab pH Probe Cleaner or mild detergent and a soft toothbrush. Rinse well to remove all traces of detergent. 5. Calibrate the pH probe

Before you can use your pen you must soak it in KCI pH Probe Refill & Storage Solution for 24 hours to hydrate the probe. A single use sachet that the meter can be stood in is provided in the box. You can also pour the liquid into a container that you can stand the meter in so that the probe is immersed for this period of time. Afterwards rinse the probe and then you will need to calibrate it. For this will you will need pH Buffer 4 and pH Buffer 7 (a single use sachet of each is provided in the box).

Product overview and how to get started

For the Bluelab Leap Probe, hold cap, twist one full turn, then gently remove. 2. Fill a small plastic container with clean tap 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. It can be very difficult to get reproducible pH reading in samples of water that have a low ionic strength, such as distilled, deionised (DI) water, reverse osmosis (RO) water or pure water. Pure water is water made only of H2O that has had all other ions removed. It theoretically will have a pH of 7 and EC of zero. It must be noted that atmospheric contamination such as the presence of carbon dioxide that forms carbonic acid in the water will acidify the pure water as due to having no ions it is not able to chemically prevent a large shift in pH from a small quantity of acid. Temperature Readings: In addition to measuring pH levels, the Bluelab pH Pen also provides temperature readings. This dual functionality is particularly useful since temperature can affect pH measurement and nutrient uptake in plants.

Bluelab is one of the industry's best-known and most trusted brands; all of their testing equipment delivers a level of reliability and accuracy that's second-to-none.

Questions & Answers

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.
