User manual for CORR Instruments' T220 P2200‑R high‑temperature, high‑pressure electrochemical electrode, covering safety, installation, calibration and…
This manual provides detailed information on the high‑temperature, high‑pressure electrochemical electrode series, including reference, auxiliary, working, ORP and glass‑based pH electrodes. The electrodes are sealed with the patented QUEON® material and are rated for up to 350 °C and 50 MPa (7500 psi), making them suitable for demanding environments such as nuclear, petrochemical, aerospace and deep‑sea research.
Safety is emphasized throughout: users must understand high‑pressure hazards, use Swagelok fittings, avoid rotating components, and keep personnel away from the test area during pressurization. The guide also explains proper cleaning, storage, and calibration procedures to ensure reliable performance and longevity of the electrodes. This manual is written in Chinese.
