This helps keep the pH level in check for the health of plants, swimmers, or aquatic life.\n- 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.\n- 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.\n- 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.\n- 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.\n\u003c\/p\u003e\u003cp\u003eProduct description\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"GreenGroove","offers":[{"title":"Default Title","offer_id":51937672888603,"sku":"B01GQVSQGG","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0991\/3516\/0603\/files\/71_ybs4c1zL._SX522.jpg?v=1774575992","url":"https:\/\/greengroove1.com\/products\/bluelab-ph-4-0-amp-7-0-calibration-solution-kit-ph-meter-amp-ph-pen-calibration-for-balanced-nutrient-solution-nist-traceable-hydroponics-gardening-amp-growing-tents-500-ml-16-9-fl-oz-eac","provider":"GreenGroove","version":"1.0","type":"link"}
