 Model: WRKC-134 WRKC-234 
 Product Note: Thermocouple order by agreement 
 Category: Thermocouple Thermocouple → corrosion 
 WRKC series carburizing furnace with reducing atmosphere such as special thermocouple 
 As a result of the series of special stainless steel or heat-resistant alloy as the thermocouple protection tube, and the formation of the entity of the seal structure, with a high temperature reducing gas corrosion resistance capabilities, suitable for high temperature carburizing furnace (900 ℃ or more ) or carbon reducing atmosphere such as the use of performance. 1996 won the national new product certification, patented product. The products are mainly used in machinery, automobiles, gears, bearings, etc. and imported equipment, carburizing furnace temperature measurement.
