Purchased as a replacement.\u003c\/p\u003e\u003cp\u003eThe liquid membrane sensor is responsible for the exchange of Potassium ions across the membrane. An imbalance develops between the sample and the internal cell in response to the Potassium ion activity. The change is proportional to the concentration of ions in solution.\u003c\/p\u003e \u003cp\u003eThe screw fixing on to the probe body (HI-4014) makes for easy replacement.\u003c\/p\u003e \u003cp\u003ePre-soaking the Potassium sensor in a dilute standard without ionic strength adjuster (ISA) for at least an hour before calibration will help to optimise the sensor response.\u003c\/p\u003e \u003cp\u003eRefrigeration of HI-4014-51 is recommended to extend its life.\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640063533429,"sku":"HI-4014-51","price":299.54,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/potassium-module-for-half-cell.jpg?v=1791580187","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-4014-51-potassium-sensing-module-for-half-cell","provider":"Test All Water","version":"1.0","type":"link"}
