I am looking for a quotation for a specific type of sensor electrode. The item should meet high-performance standards, including a temperature range of 300-600°C and an insulation resistance of 2500 QM. It must be designed for prolonged use, with a working time of 8000 to 10,000 hours under pressure conditions of 21-31 MPa. The preferred material is high-quality alumina ceramics, and I would like the installation method to be screw-in. Additionally, please include information about spare parts such as porcelain terminals and copper washers. Thank you!
