ii) FLP enclosure suitable for classified hazardous areas. LM-6alloy enclosure certified for IIA/ IIB/ IIC gas groups. IP55protection.


Single most important andexpensive component. Total system reliability and effectivenessdepends upon this. It is important to use right sensor based onapplication

  • All sensors of high sensitivity (semiconductor / electrochemical)
  • All sensors are sourced from ISO 9001 certified manufacturers of international repute
  • All sensors are carefully selected for the target gas and do not respond to other interfering gases
  • Very low warm up and response times
  • Expected life 2 to 10 years (depending upon sensor type)
  • All sensors are housed in appropriate housing and assembled for enhanced safety and environment protection
