Product Details

Ensures accurate readings - Our pH calibration solution helps maintain the accuracy and reliability of a pH pen, probe, or tester. Calibration ensures accurate readings. This helps keep the pH level in check for the health of plants, swimmers, or aquatic life. NIST Traceable - Our pH calibration solutions are NIST traceable and meet the highest quality standards. This set includes two crucial pH levels, pH 4 and pH 7, allowing you to calibrate a wide range of pH instruments. Improves the longevity of the pH pen or tester - Regular calibration helps extend the life of your pH meters by maintaining their performance. Useful for providing accurate pH in hydroponics, aquariums, swimming pools, or gardens. Easy-to-use and long shelf life - Our electrolyte solutions are ready-to-use right out of the bottle, saving you time and effort. Our pH calibration solutions don't need frequent replacements as they have a long shelf life. How to calibrate - Make sure your pH pen or probe is clean and hydrated. Turn it on. Place the probe tip in a fresh pH 7.0 calibration solution. Rinse the pen or probe tip in clean tap water and shake off the excess. Calibrate to pH 4. A calibration confirmation will appear to show a successful calibration. Recalibrate if the symbol disappears.
