VHT500 Single-mode Series

Verrillon VHT500 is a pure silica core single-mode design with a protective metal coating that allows it to operate at temperatures up to 500°C. Typically, these fibers are used in down-hole data logging for enhanced supercritical geothermal applications, hightemperature oil/gas downhole monitoring using acoustic, strain and temperature sensing, and downstream oil process monitoring.
