Premium Materials & Certified Grades of Explosion-Proof Thermocouple
Every product is built with high-quality materials to withstand harsh hazardous conditions. Its thermoelectrodes include K-type (NiCr-NiSi) for general medium-high temperatures, S-type (PtRh10-Pt) for high-precision high temperatures, and B-type (PtRh30-PtRh6) for ultra-high temperatures. The explosion-proof junction box uses cast aluminum (cost-effective for non-corrosive areas) or 304/316 stainless steel (corrosion-resistant for chemical environments), while protective tubes vary from 304/316 stainless steel (general use) to Hastelloy (corrosive media) and corundum ceramic (high temperatures above 1000℃).
Following national standards, the product offers Class Ⅰ and Ⅱ accuracy, with explosion-proof grades clearly marked (e.g., Ex d ⅡC T4 Gb).
