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\u003cbr\u003e\u003ch3\u003eCPS™ Sleeve Junction\u003c\/h3\u003e\u003cbr\u003e\u003cp\u003eClogging Prevention System (CPS™) technology is an innovation in electrode technology. Conventional ORP electrodes use ceramic junctions that clog quickly when used in wine. When the junction is clogged, the electrode does not function. CPS technology utilises the porousness of ground glass coupled with a PTFE sleeve to prevent clogging of the junction. The ground glass allows proper flow of the liquid, while the PTFE sleeve repels dirt. As a result, ORP electrodes with CPS stay fresh up to 20 times longer than conventional electrodes.\u003c\/p\u003e\u003cbr\u003e\u003ch3\u003eGlass Body\u003c\/h3\u003e\u003cbr\u003e\u003cp\u003eThe glass body is ideal for laboratory use.
