Infrared camera for SF6 Gas Detection TC706

Infrared camera for SF6 Gas Detection TC706

The TC706 visualizes and pinpoints gas leaks of SF6, without the need to de-energize high-voltage equipment or shut down the operation. The portable camera also greatly improves operator safety, by detecting emissions at a safe distance, and helps to protect the environment by tracing leaks of environmentally harmful gase.

SF6 is used in the electric power industry as an insulator and quenching medium for gas-insulates substatios and circuit breakers.

TC706 – Great choice for Gas Leaks Detection

Could detect following gases:

  • SF6
  • Chlorine dioxide
  • Ethylene
  • Ammonia
  • Acetic acid
  • MEK
  • Cyanoacrylate
  • FREON-12

TC706 Unique Feature:

  • Adapt passive thermal imaging technology, could accurately find the leakage point at long distance without power supply shutdown
  • Using Cooled QWIP detector, enjoy superior image quality and accurate temperature measurement
  • Voice and video recording function
  • HD OLED view finder, combined with 5” touch rotating screen, suitable for many on-site using
  • No specific background and auxiliary light needed, suitable for many on-site checking
  • Small size, light weight and easy operation, suitable for single person on-site using
