Electrodes can become dirty from use and will produce inaccurate results even as they read correctly in a pH buffer. Hanna's® cleaning solutions eliminate impurities and residues that are left on electrode surfaces when immersed in samples during measurement or when stored incorrectly. Hanna suggests cleaning the bulb and junction of your electrode on a regular basis to ensure that the probe is always clean and to prevent any clogging of the junction. \u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":58455585161519,"sku":"114186","price":26.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/4875\/4479\/files\/82248e62C10095.jpg?v=1789184775"},{"product_id":"hanna-electrode-storage-solution-500ml","title":"Hanna Electrode Storage Solution - 500ml","description":"\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":58455659446575,"sku":"114283","price":31.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/4875\/4479\/files\/805dcf4034-0805.jpg?v=1789186577"},{"product_id":"apera-ph-calibration-kit-ph-4-7-10-8-oz-each","title":"Apera pH calibration Kit (pH 4\/7\/10, 8 oz. each)","description":"\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eGroStar by Apera pH calibration kit (pH 4\/7\/10, 8 oz. each)\u003c\/p\u003e\n\u003cp\u003eKit Includes:\u003c\/p\u003e\n\u003cp\u003e(1) pH 4.0 calibration solution 8 oz.\u003c\/p\u003e\n\u003cp\u003e(1) pH 7.0 calibration solution 8 oz.\u003c\/p\u003e\n\u003cp\u003e(1) pH 10.0 calibration solution 8 oz.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003epH measuring equipment must be cleaned and calibrated regularly to ensure accurate readings\u003c\/li\u003e\n  \u003cli\u003eHigh accuracy (0. 01 pH): standardized against NIST Certified pH references within 0. 01 pH at 25˚C (77˚F). ideal for the calibration of all pH meters\u003c\/li\u003e\n  \u003cli\u003eColor-coded, double-sealed, 1-year shelf life\u003c\/li\u003e\n  \u003cli\u003eExpiration date and temperature\/ph reference chart provided for reference\u003c\/li\u003e\n  \u003cli\u003eNon-hazardous product\u003c\/li\u003e\n  \u003cli\u003eCalibration Solution should be stored in a cool place out of direct sun and heat\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Apera Instruments","offers":[{"title":"Default Title","offer_id":58455699423535,"sku":"114422","price":28.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/4875\/4479\/files\/62f2e9c7AI61115_1.jpg?v=1789187487"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/4875\/4479\/collections\/e9cadcf6107641.jpg?v=1789069895","url":"https:\/\/mattshydroponics.com\/collections\/hydroponics-meters-and-solutions.oembed","provider":"Matt’s Hydroponics","version":"1.0","type":"link"}
