It also can sense that hot water is being put through the unit and automatically shuts off. There has been some discussion about electrodes on Water Ionizers. The electrodes are composed of Solid Titanium with a Dip-treatment platinum coating, which is the standard in the industry. Titanium is used because it is extremely hard. The platinum is coated, NOT electroplated, on to the titanium.
Platinum is used because it is an excellent conductor.
The Technos does NOT use stainless steel electrodes as has been suggested by other companies. Stainless steel was used for Water Ionizer electrodes in the late 1980's and was found not be a suitable material because they did not last more than a a few years. The industry began using titanium platinum-coated electrodes as a whole in the early 1990's because it will last indefinitely. At present, no one is manufacturing Water Ionizers with stainless steel electrodes. Some companies claim to have solid platinum electrodes on their water ionizers.
