Explosion-proof infrared (IR3) digital flame detector


  • 021k_03.png

Ultra-small Digital Infrared Three-wavelength Flame Detector
State-of-the-art technology that improved dramatically the alarms for non-fire situations

The effective sensing distance sensitivity can be maintained as it is from the energy source emitting flame-like energy.

- Stylish design
- Weight: 650g (including cable gland)
- Size: diameter 50mm / length 46mm
