This is the factory-spec BNC-connector pH probe built to the original S300 Pro2 specification.\u003c\/p\u003e\u003cp\u003eSubstrate pH probes take more physical punishment than a probe that only ever sits in liquid, since they are pushed in and out of solid growing media on every use, so they naturally wear faster and are worth keeping a spare of if the meter is used regularly. It is IP67 waterproof and fits the same connector as the original electrode, giving a straightforward swap with no other changes needed to keep the S300 Pro2 running accurately.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine replacement electrode\u003c\/strong\u003e built to original S300 Pro2 specification\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBNC connector\u003c\/strong\u003e for direct-fit swap onto the meter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP67 waterproof\u003c\/strong\u003e for repeated insertion into wet substrate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt for the physical wear\u003c\/strong\u003e of direct substrate insertion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRestores accuracy\u003c\/strong\u003e once the original probe wears down\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003eCompatible with: Aqua Master Tools S300 Pro2 Substrate pH\/Temp meter\u003c\/li\u003e\n\u003cli\u003eConnector: BNC\u003c\/li\u003e\n\u003cli\u003eWaterproof rating: IP67\u003c\/li\u003e\n\u003cli\u003eMeasures: pH (substrate, direct insertion)\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"Aqua Master Tools","offers":[{"title":"Replacement Electrode","offer_id":53500712091914,"sku":"AMT-S300PRO2-PH-ELECTRODE","price":63.55,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/s300-pro-2-ph-electrode-4897-en-G.jpg?v=1786377504","url":"https:\/\/hydrocropshop.co.uk\/products\/aqua-master-tools-s300-pro2-ph-substrate-replacement-electrode","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
