The glass is resistant to many harsh chemicals and is easily cleaned. The glass body also allows for a fast transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature dependent. The faster the equilibrium the steadier the reference potential.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: flex-start; gap: 16px 24px;\"\u003e\n\u003cdiv style=\"flex: 0 0 140px; max-width: 100%; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/singleceramic_double_junction.png\" alt=\"single ceramic\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 200px; min-width: 0;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eSingle Ceramic Junction\u003c\/h4\u003e\n\u003cp\u003eThe outer junction of an electrode,  also known as a salt bridge,  is necessary component of the electrical circuit. The movement of ions must flow through the junction for a steady reading. The outer reference has a single ceramic frit. The ceramic is a porous material that is easily fused with the glass body and has a similar expansion coefficient. A single ceramic junction has a flow rate of 15-20 µL\/hour. Other junction types are available with higher flow rates and made with different materials.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: flex-start; gap: 16px 24px;\"\u003e\n\u003cdiv style=\"flex: 0 0 140px; max-width: 100%; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/refillable.png\" alt=\"refillable\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 200px; min-width: 0;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eRefillable\u003c\/h4\u003e\n\u003cp\u003eThe HI5412 is a refillable reference electrode. Since it is a double junction electrode the fill solution is the HI7082 3.5M KCl. This solution does not contain any silver as with single junction electrode. The absence of silver will prevent any silver precipitate from forming at the junction surface and clogging it. Clogging of the junction will result in drifty and erratic readings.\u003c\/p\u003e\n\u003ch5\u003e4 mm Connector\u003c\/h5\u003e\n\u003cp\u003eThe HI5412 uses a 4 mm banana connector. This type of connector is easily plugged into the reference input on suitable meters. Other type of connectors include BNC,  DIN,  screw type,  T-type,  and 3.5mm to name a few. These types of connectors tend to be proprietary for a particular type of meter and are not interchangeable.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"text-align: center; margin: 0 0 48px;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Screen_Shot_2015-03-17_at_3.24.19_PM.png\" alt=\"half cell electrode\" loading=\"lazy\" style=\"display: block; max-width: min(100%, 640px); height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e HI5412\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e Glass Body Calomel Reference Electrode - HI5412\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReference Cell Type\u003c\/td\u003e\n\u003ctd\u003e single, Hg\/Hg₂Cl₂\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eJunction Type\/Flow Rate\u003c\/td\u003e\n\u003ctd\u003e ceramic, single \/ 15-20 µL\/h\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRefill Electrolyte\u003c\/td\u003e\n\u003ctd\u003e 3.5M KCl\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003e glass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax.
