As shown in figure 20, PTFE integument 520 in thermocouple wire (two) 510 outer wrapping.The medium temperature that thermocouple induction head and thermocouple probe 530 directly contact should be equal to or be substantially equal to the temperature of acid solution, for this, thermocouple induction head close contact PTFE integument should be made, PTFE integument directly contacts acid solution, it is believed that the temperature of PTFE integument is equal to the temperature of acid solution. For ensureing the close contact of this thermocouple induction head and PTFE integument, in the example depicted in fig. 5, hot-press method is adopted to make probe and PTFE wall perfect adaptation in the position that namely thermocouple induction head pops one's head in. Further, interfere for stopping cool ambient air entrance, wire devises multiple seal point 540, is also adopted by hot-press method and seals. Replacement as hot-press method, it would however also be possible to employ welding method reaches the purpose of close contact.

Thermocouple leads line is such as capillary thermocouple call wire, for instance external diameter is about 0.8mm, and thermocouple gauge bread wraps up in the PTFE integument of wall thickness about such as 0.5mm. PTFE material can tolerate 250 degree of high temperature and strong acid and strong base corrosion, is equivalent to put on layer protecting film to thermocouple, serves etch-proof effect. And probe positions is fully combined with thin-walled by hot-press method or welding method, and thermometric is more accurate, more rapid.
