An ORP sensor must be chemically inert; it cannot be oxidised 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\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eGlass Body \u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThe glass body is ideal for laboratory use.
