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

Product Information

To ensure proper cleaning, use the Bluelab pH Probe Care kit (or use a mild dish washing liquid) and follow the steps below. 1. Remove cap 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. Calibration: Before using the pH meter, it’s important to calibrate it to ensure accurate readings. The Bluelab pH Meter usually comes with pH 4.0 and 7.0 calibration solutions. To calibrate, immerse the probe into the calibration solution and adjust the meter as per the instructions until it reads the correct pH value. Repeat this step with the second calibration solution. Remember, the Bluelab pH Meter is a sensitive device. Avoid touching the probe tip with hard objects or your fingers, as it can affect the accuracy of the readings. Always refer to the product manual for specific instructions and troubleshooting tips.

FAQ and troubleshooting for the Bluelab pH Pen and Bluelab Soil pH Pen Find answers and solutions to common questions for the Bluelab pH Pen, and the Bluelab Soil pH Pen Bluelab pH Pen User Manual - English - Spanish - German Deutsch - Dutch - Latin American Spanish - Canadian French 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. Adding a small quantity of calcium magnesium (calmag) is often used to add a controlled quantity of ions that act as a natural buffer (to chemically prevent large shifts in the pH when a small quantity of acid or base is added) and provide a source of ions to then allow a reliable pH reading to be taken.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.

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. 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).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. Soak probe in KCl storage solution for 24 hours and retest. Don't measure proteins or oils with the pH pen. 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. 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.

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. Unboxing and Initial Setup: After unboxing the Bluelab pH Meter, install any batteries if required. Make sure all parts of the device are secure and undamaged. Minimise the exposure of the sample to air as CO2 absorption can decrease pH. CO2 will react with water to make carbonic acid and shift the pH to below 7 (more acidic). Due to having no ions present, the solution cannot mediate this change (no buffering action) and the change in pH will be larger than it should be for the amount of acid present. 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:Storage solution is used to ensure a pH probe is kept in idealconditions during storage, while the probe is not in use. Read more about KCl solution. 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. 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.

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.
