Download Product Documentation


The Senscient ELDS laser-based open path gas detector is available for a wide range of toxic and flammable gases. The Senscient ELDS uses 'SimuGas' self-testing to eliminate employees entering hazardous areas for gas checks. Nuisance false alarms are virtually eliminated with its breakthrough Harmonic Fingerprint processing.


  • Gases detected: hydrogen sulfide (H2S), sour gas (H2S/CH4), methane (CH4), ethylene (C2H4), ammonia (NH3), carbon dioxide (CO2), hydrogen chloride, (HCl), hydrogen fluoride (HF).
  • Gas-specific Harmonic Fingerprint detection eliminates false alarms and prevents plant shutdowns.
  • SimuGas automated function checks are recorded daily and eliminate need for manual intervention.
  • Tuneable lasers scan more narrow portion of spectrum where water interference from weather conditions are minimized.
  • Bluetooth wireless technology and SITE software simplifies commissioning, diagnostics, and event log retrieval.
  • Senscient ELDS lasers are hard on fog, rain, and snow but are easy on the eyes with a Class 1 eye-safe designation.
  • Fastest responding device for safety critical ventilation zone and cross duct applications.
  • No costly communication cable required between transmitter and receiver.
  • Significantly improves the safety, efficiency, and operational costs of your gas detection program.
