Flammable Gas Detector

Flammable gases detection and criminal explosion prevention

Designed for ATM complex protection.

  • Flammable gases detection and criminal explosion prevention
  • Detection of 10% gas concentration of the explosive limit
  • Feeding of the substance matter preventing explosion
  • High level of reliability
  • Two gas concentration thresholds generate alarm messages
  • Long life-time semiconductor sensing element
  • Power supply, V DC ‒ 12V
  • Low power consumption
