This design consideration is ideal for laboratories and general purpose oxidation reduction reaction measurements.\u003c\/p\u003e\n\u003cp\u003eHanna Instruments offers a wide variety of electrodes that are designed for many different applications. The sensing type, body material, kind of junction and reference, plus electrolyte used are just some of the design considerations.\u003c\/p\u003e\n\u003cp\u003eThe HI-36183 uses a platinum pin, glass body, single ceramic junction and is refillable with 3.5M KCl + AgCl.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt-In Temperature Sensor\u003c\/li\u003e\n\u003cli\u003eRefillable Electrode\u003c\/li\u003e\n\u003cli\u003ePlatinum Sensing Pin\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePlatinum Sensing Pin\u003c\/h3\u003e\n\u003cp\u003eThe HI-36183 ORP sensor is made with platinum. 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 a similar thermal coefficient.\u003c\/p\u003e\n\u003ch3\u003eGlass Body\u003c\/h3\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 faster the equilibrium the steadier the reference potential.\u003c\/p\u003e\n\u003ch3\u003eSingle Ceramic Junction\u003c\/h3\u003e\n\u003cp\u003eThe outer junction of an electrode, also known as a salt bridge, is a 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 frit 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\u003ch3\u003eRefillable\u003c\/h3\u003e\n\u003cp\u003eThe HI-3618B is a refillable probe. Since it is a single junction ORP electrode the fill solution is the HI-7071 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\u003ch3\u003eQuick Connect DIN Connector\u003c\/h3\u003e\n\u003cp\u003eThe HI-36183 uses a Quick Connect DIN connector that makes attaching and removing the probe simple and easy. This type of connector is proprietary to the meter.
