S type thermocouple assembles with protection head and corundum thermowell, should use wooden case for packing. Its thermo wire diameter is Ф0.5mm. S type thermocouple has high accuracy and good stability, can directly measure the temperature of liquid, vapor, gas medium and solid surface in the range of 0~1200 ℃ in various production processes.

Tips: Protection head of thermocouple
Protection head of thermocouple is used to fasten connector and connect external wire so as to protect thermode from external corrosion and wires and connect binding post well. Moreover, it forms temperature-sensing element of thermocouple together with thermode, insulating bush and connector. It is generally made into universal parts to install in different thermowells and protection head. There are three kinds of protection heads: All stainless steel protection head, waterproof protection head and explosion-proof protection head.

ATO Responded

Unfortunately, we do Not provide thermocouples in 15 inch lengths, available in 300mm and 600mm lengths.

Satisfying purchase，good quality

This thermocouple works great in our heat treatment oven, and in good condition even temperatures of 1200°C. We are very satisfied. Hope it can work longer!
