Corrosion-resistant Thermocouple
Brief DescriptionWRE-330F Corrosion-resistant Thermocouple includes type K and E. It’s a temperature detector widely used in high and middle temperature field with high accuracy and stable performance. The platinum thermal resistance measurement accuracy is the highest; w
DetailsTechnical parameters
Protection Tube
| Protection Tube material | Applications environment |
| stainless steel（0Cr18Ni12Mo2Ti） | Used for weak corrosive medium like industrial water, domestic water and sewage, applicable to petroleum, chemical industry, iron and steel industries and municipal, environmental protection and other fields. |
| Hastelloy B | With good corrosion-resistant performance to hydrochloric acid below boiling point, as well as non chloride acid & alkali like sulfuric acid, phosphoric acid, hydrofluoric acid, organic acids and other non oxidizing salt solution. |
| Hastelloy C | Non oxidizing acid-resistant, such as nitric acid, mixed acid, or a combination of chromic acid and sulfuric acid, as well as Inoxidizability salt resistant which contains Fe++ +, Cu++ or other oxidizing agent like hypochlorite solution and sea water which are higher than normal temperature. |
| Titanium | Corrosion-proof of sea water, all kinds of chloride and hypochlorite, oxidizing acid (including fuming sulfuric acid), organic acid, alkali. Not resist corrosion from pure reducing acid, such as quicksand, hydrochloric acid, but when acid contains oxidizing agent such as acid (such as nitric acid, Fe++ +, Cu++), the corrosion is greatly reduced. |
| PTFE | As one plastic of the most stable chemical performance, it can resist boiling hydrochloric acid, sulfuric acid, nitric acid and aqua regia, strong alkali and a variety of organic solvents. But it doesn’t resist three chlorine fluoride, high temperature chlorine, high-speed liquid fluoride, fluoride liquid oxygen, ozone, etc. |
