It contains a platinum cathode and silver anode and is for use with HI-76407A\/P PTFE membrane caps. The probe’s tapered design makes it ideal for BOD measurements.\u003c\/p\u003e\u003cp\u003eThe HI-76407\/20 is a Polarographic dissolved oxygen probe with internal temperature sensor and a 20m cable.\u003c\/p\u003e \u003cp\u003eHanna Dissolved Oxygen probes are extremely rugged and perfect for laboratory and field applications.\u003c\/p\u003e \u003cp\u003eCalibration is fast and simple, and measurements are temperature compensated. The sensitive PTFE (PolyTetraFluoro-Ethylene) membrane can be changed in a few seconds.\u003c\/p\u003e \u003cp\u003eThe HI-76407\/20 is a standard polarographic dissolved oxygen probe for HANNA benchtop and portable dissolved oxygen meters. The probe is made of durable ABS plastic and contains an integrated temperature sensor for temperature compensated measurements. It is compatible with our HI-76407A\/P PTFE membrane caps. Each membrane separates the probe’s platinum cathode and silver anode from the water sample being measured. Oxygen diffuses across the membrane and interacts with the polarographic system to produce a current proportional to oxygen concentration. Each cap is easily filled with HI-7041 electrolyte and screwed onto the probe.\u003c\/p\u003e \u003ch3\u003eKey features:\u003c\/h3\u003e \u003cul\u003e \u003cli\u003ePolarographic Sensor\u003c\/li\u003e \u003cli\u003eTapered\u003c\/li\u003e \u003cli\u003eShielded, waterproof cable\u003c\/li\u003e \u003cli\u003eCable protective sleeve\u003c\/li\u003e \u003cli\u003eLinearised and accurate thermistor temperature sensor protected behind a stainless steel cover\u003c\/li\u003e \u003cli\u003eSilver wire anode element\u003c\/li\u003e \u003cli\u003eGlass encapsulated platinum cathode\u003c\/li\u003e \u003cli\u003eScrew cap membrane that holds potassium chloride electrolyte solution (HI-7041S)\u003c\/li\u003e \u003cli\u003eThin, permeable PTFE membrane isolates the sensor elements from the testing solution, but allows oxygen to enter (Hi-76407A\/P)\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003e\u003c\/h3\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eShielded, waterproof cable\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtective sleeve\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePEI probe\u003c\/td\u003e\n\u003ctd\u003eBest field protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThermistor temperature sensor\u003c\/td\u003e\n\u003ctd\u003eLinearised and accurate and protected behind a stainless steel cover\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnode\u003c\/td\u003e\n\u003ctd\u003eSilver wire element\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCathode\u003c\/td\u003e\n\u003ctd\u003eGlass encapsulated Platinum cathode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMembrane\u003c\/td\u003e\n\u003ctd\u003eScrew cap membrane that holds potassium chloride electrolyte solution (HI-7041S)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePTFE membrane\u003c\/td\u003e\n\u003ctd\u003eThin, permeable PTFE membrane isolated the sensor elements from the testing solution, but allows oxygen to enter (HI-76407A\/P)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHole for solution cycling\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtective sleeve\u003c\/td\u003e\n\u003ctd\u003eYes – ideal for field applications\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReplacement membranes\u003c\/td\u003e\n\u003ctd\u003eOrder HI-76407A\/P x 5 ready-to-use replacements\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eElectrolyte Solutions\u003c\/td\u003e\n\u003ctd\u003eHI-7041 Refilling electrolyte solution (6 x 30ml) HI-7041S Refilling electrolyte solution (30ml) HI-7041M Refilling electrolyte (230ml) HI-7041L Refilling electrolyte solution (500ml)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640084078965,"sku":"HI-76407\/20","price":545.01,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/dissolved-oxygen-probe-with-20m-cable.jpg?v=1791580865","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-76407-20-dissolved-oxygen-probe-with-20m-cable","provider":"Test All Water","version":"1.0","type":"link"}
