After establishing the compact flame monitor F200K successfully and it is proven that it is at its best with combustion of any kind (oil, gas etc.), LAMTEC now offers this compact flame monitor in explosive proof design for different issues.
The following type shows a wide range of applications for combustion plants especially for the chemical or petrochemical industry.

Sensitivity features:

  • 2 sensitivity sections
  • 6 steps selectable for each sensitivity section
  • externally switchable
  • Increased sensitivity in section 2
