The Senscient ELDS laser-based open path gas detector is available for a wide range of toxic and flammable gases.

The Senscient ELDS utilises ‘SimuGas’ self-testing to eliminate the need for employees to enter hazardous areas for gas checks. Nuisance false alarms are virtually eliminated with its breakthrough Harmonic Fingerprint processing.

Highlights

• Gases detected: hydrogen sulfide (H2S), sour gas (H2S/CH4), methane (CH4), ethylene (C2H4), ammonia (NH3), carbon dioxide (CO2), hydrogen chloride (HCl).
• Gas-specific Harmonic Fingerprint detection eliminates false alarms and prevents plant shutdowns.
• SimuGas automated function checks are recorded daily, eliminating the need for manual intervention.
• Tunable lasers scan a narrow portion of the spectrum where water interference from weather conditions is minimised.
• Bluetooth wireless technology and SITE software simplify 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 zones and cross-duct applications.
• No costly communication cable is required between the transmitter and receiver.
• Significantly improves the safety, efficiency, and operational costs of your gas detection program.
