While pH 7.0 defines the neutral point, pH 4.0 corrects the error rate in the acidic range, where most nutrient solutions for plants are found (typically pH 5.5 to 6.5). Without regular calibration with pH 4.0, your device may show correctly at pH 7.0, but incorrectly output 6.2 at an actual value of 5.8 – a difference that can determine the success or failure of your harvest.\u003c\/p\u003e\n\u003cp data-path-to-node=\"8\"\u003e\u003cb data-path-to-node=\"8\" data-index-in-node=\"0\"\u003eApplication Tip:\u003c\/b\u003e Always rinse your meter's electrode thoroughly with distilled water between calibration steps (from pH 7.0 to pH 4.0). This prevents cross-contamination of the calibration fluids and ensures that the buffer solutions in your test vessel remain pure.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"9\"\u003eProduct Data:\u003c\/h3\u003e\n\u003cul data-path-to-node=\"10\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,0,0\"\u003e\u003cb data-path-to-node=\"10,0,0\" data-index-in-node=\"0\"\u003eContents:\u003c\/b\u003e 500 ml\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,1,0\"\u003e\u003cb data-path-to-node=\"10,1,0\" data-index-in-node=\"0\"\u003epH Value:\u003c\/b\u003e 4.0 (at 25 °C)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,2,0\"\u003e\u003cb data-path-to-node=\"10,2,0\" data-index-in-node=\"0\"\u003eColor:\u003c\/b\u003e Usually color-coded (red) to prevent confusion with pH 7.0.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,3,0\"\u003e\u003cb data-path-to-node=\"10,3,0\" data-index-in-node=\"0\"\u003eStorage:\u003c\/b\u003e Store tightly closed in a cool, dark place.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Aqua Master Tools","offers":[{"title":"Default Title","offer_id":60885215740234,"sku":null,"price":14.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0917\/5554\/4906\/files\/amt1303-4875-de-G_709632fb-0a5f-44a2-95de-c907b9077ca4.jpg?v=1769032783","url":"https:\/\/www.growzeche.de\/en\/products\/aqua-master-tools-eichflussigkeit-4","provider":"Grow Zeche","version":"1.0","type":"link"}
