An ORP sensor must be chemically inert; it cannot be oxidized or reduced itself. It must also have the proper surface characteristics to promote rapid electron exchange,  a property known as high exchange current density. Two noble metals have proven to work well for this purpose: platinum and gold. Pure platinum and pure gold are both used in the construction of ORP sensors. The gold sensor signal is carried through the electrode body,  and together with the reference signal is conducted to the measurement meter.\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\/HI4430_PEI.png\" alt=\"PEI Body\" 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;\"\u003ePEI Body\u003c\/h4\u003e\n\u003cp\u003eThe body of the HI4430B is composed of polyetherimide (PEI) resin. The PEI body is suitable for a wide range of applications and excels in field measurements due to its durability. The shielding around the spherical glass tip minimizes breakage due to accidental bumping or dropping of the electrode. The PEI plastic is a high quality plastic that is chemically resistant to many aggressive chemicals.\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\/HI4430_junction.png\" alt=\"Ceramic Junction\" 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\/bnc.png\" alt=\"BNC connector\" 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;\"\u003eBNC Connector\u003c\/h4\u003e\n\u003cp\u003eThe HI4430B uses a BNC connector.
