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: pure platinum and pure gold are both used in the construction of ORP sensors. The platinum sensor is often preferred because it is mechanically simpler and safer to produce. Platinum can be welded to glass and has the same thermal coefficient. The platinum 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\/HI3618_glass.png\" alt=\"Glass 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;\"\u003eGlass Body\u003c\/h4\u003e\n\u003cp\u003eThe glass body is ideal for laboratory use. 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 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\/HI3618_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 HI3618B is a refillable probe. Since it is a single junction ORP electrode the fill solution is the HI7071 3.5M KCl + AgCl. If using a refillable ORP electrode,  the fill cap should be removed prior to measurement. Removing the cap creates positive head pressure in the reference cell allowing for higher flow rate of electrolyte through the outer junction. A higher flow rate will result in a faster and more stable reading.\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\/FC214D_DinConnector.png\" alt=\"DIN 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;\"\u003eDIN Connector\u003c\/h4\u003e\n\u003cp\u003eThe HI3618D uses a DIN connector.
