Product Introduction
The TR□K□-437FQFG series corrosion-resistant thermocouples are suitable for applications in flues, desulfurization, and denitrification devices. Ordinary stainless steel sheaths are prone to embrittlement due to acid corrosion, and cannot withstand high temperatures after tetrafluorine (likely a typo for tetrafluoro' or more commonly, referring to fluoroplastic coatings which have temperature limits; but in context, it might mean coatings or treatments that are not suitable for high temps if damaged) treatment, which also affects heat response time. The external protective tube of this product adopts a metal sheath with a surface treatment involving the dissolution of a metallic ceramic layer (or more smoothly: is treated with a metal-ceramic composite coating on the surface), providing excellent resistance against H2S corrosion and possessing certain wear resistance, effectively solving the problem of acid corrosion
