We have a well equipped production unit, loaded with advanced technology machines and tools, enabling us to manufacture and supply a quality range of Bio Gas Detection. Our detectors provide effective solution to the biogas, oil wells and gas turbines by detecting any leakage of combustible gases. To manufacture the detectors, we use high quality materials and components, sourced from trusted vendors. We offer our Bio Gas Detection at the market leading prices. 


  • Accurate detection
  • Easy handling
  • Highly efficient 

Further Details:

The Aero sense IR-5500 provides an effective solution for protection against hazardous gases by detecting wide range of combustible gases and CO2 simultaneously.


  • Higher accuracy and better lifetime achieved using NDIR sensor Technology.
  • Optimized for detection of smallest leak of combustible gases and Carbon Dioxide.
  • Highly resistant to poisoning and etching.
  • Capable of detecting down to PPM, %LEL, %V/V, mg/m3.
  • Auto ranging of Gas Concentration from PPM to %V/V & %LEL.
  • Digital Alphanumeric display with Auto backlit.
  • Standard 4-20mA signal output proportional to Gas concentration range.
  • Easy handling and programming with 3 keys.
  • Can be programmed using Remote Control from 10 meters line of site distance.
  • Non - Intrusive programming for Flameproof models using Magnetic pen.
  • Password protected programming menu.
  • One man Auto software Gas calibration.
