Most hydro and coco growers aim for roughly 5.5–6.5 and soil growers slightly higher, so checking every fresh mix and adjusting with pH up or down is one of the simplest ways to keep plants healthy.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibrate first:\u003c\/strong\u003e dissolve a buffer sachet in the stated volume of distilled water, dip the pen and calibrate using the CAL function until it reads the buffer value.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasure:\u003c\/strong\u003e remove the cap, dip the electrode into the solution, stir gently and wait for the reading to settle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjust:\u003c\/strong\u003e correct the feed with pH up or pH down and re-test.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCare:\u003c\/strong\u003e rinse the tip with clean water after use, replace the cap and recalibrate regularly.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Digital pH pen\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRange:\u003c\/strong\u003e 0.0 – 14.0 pH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay:\u003c\/strong\u003e LCD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControls:\u003c\/strong\u003e ON\/OFF, CAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupplied with:\u003c\/strong\u003e buffer powder sachets (pH 4.00, 6.86, 9.18), storage case\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"Hydro Crop Shop","offers":[{"title":"Default Title","offer_id":53803796136202,"sku":"TLS-HYDR-021-01","price":18.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/digital-ph-meter-1.png?v=1790229400","url":"https:\/\/hydrocropshop.co.uk\/products\/digital-ph-meter","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
