A dirty electrode is one of the most common reasons, and HY-GEN Probe Cleaning Solution is made for exactly that job. It removes the organic and inorganic contaminants that coat and clog pH electrodes and slow their response. It cleans conductivity (EC) meter electrodes too, which means one bottle looks after the two meters a hydroponic grower leans on most.\u003c\/p\u003e\u003cp\u003eWhy does a probe get sluggish in the first place? A pH electrode reads through a thin glass bulb that responds to hydrogen ions in the solution, alongside a reference junction that has to stay in open contact with whatever it's measuring. Nutrient salts, organic matter from feeds and additives, and general reservoir grime slowly build up on both. Once the glass is coated or the junction is partly blocked, the meter has to read through that layer. You see it as a slow, wandering number. EC electrodes have their own version of the problem: deposits on the sensing surfaces sit between the metal and the solution and throw the reading off.\u003c\/p\u003e\u003cp\u003eThat's why HY-GEN recommend cleaning before every calibration and before a meter goes into storage. Calibrating a dirty electrode only sets the meter against a reading that's already compromised. Clean it first and the calibration has something accurate to hold onto. Regular cleaning also helps a meter last longer and keeps the electrode performing at its best.\u003c\/p\u003e\u003cp\u003eHY-GEN make it from high quality analytical grade constituents to international standards, and describe it as the same quality laboratories use for cleaning and storing electronic meters.\u003c\/p\u003e\u003cp\u003eIts partner is HY-GEN pH Electrode Storage solution. A freshly cleaned pH electrode belongs in it whenever it isn't in use, and never dry, in buffer or in distilled water.\u003c\/p\u003e","brand":"HY-GEN","offers":[{"title":"250 ml","offer_id":67551784272030,"sku":"9334851000935","price":8.99,"currency_code":"AUD","in_stock":false},{"title":"500 ml","offer_id":67551784304798,"sku":"PLACEHOLDER920007","price":11.25,"currency_code":"AUD","in_stock":false},{"title":"1 L","offer_id":67551784337566,"sku":"9334851000959","price":22.49,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/5261\/6094\/files\/HY-GEN_Probe_Cleaning_Solution_01.png?v=1793776461","url":"https:\/\/www.hydrooasis.com.au\/products\/hy-gen-probe-cleaning-solution","provider":"Hydro Oasis","version":"1.0","type":"link"}
