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

Product Information

Get your nutrient temperature right to fight root diseases, improve growth and boost nutrient uptake further. 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. 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. 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 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

User-Friendly: Despite its professional-grade features, the Bluelab pH Meter is easy to use. The simple, clear instructions make it accessible for beginners as well. 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.Add a small amount of Bluelab pH Probe Cleaner or mild detergent to the water. 3. Gently stir the probe tip in the mixture 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. 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. 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? 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.

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. Take a small sample of the water to be measured rather than measuring direct into large volumes to avoid any likelihood of electrostatic interference. Our Bluelab pH Probe KCl (Potassium Chloride) Storage Solution is a storage solution designed specifically for use with Bluelab pH Pens or pH Probes.

Why your pH reading may not be stabilizing, and what this has to do with ionic content, or ionic strength.

Bluelab's pH products are charged with reference material which expends over time and use. The average life span of a pH pen is approximately 18 months. Good care will help to maintain your pen. Follow our guides to proper hydration, regular cleaning and calibration. Pinpoint your pH & temperature with a single tool — a 2-in-1 Bluelab pH Pen. 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. 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. 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.
