    Detect Gas Leaks Earlier. Virtually Eliminate False Alarms. Reduce Maintenance.

    Designed to help industrial facilities detect combustible and toxic gas leaks over long distances while reducing nuisance alarms, minimizing routine maintenance, and improving operational efficiency.

    Detect Gas Leaks Earlier

    Laser-based Enhanced Laser Diode Spectroscopy (ELDS™) provides highly selective open path gas detection, enabling rapid identification of combustible and toxic gas leaks across large industrial areas.
    • Detects gases up to 200 m (656 ft)
    • Long-range line-of-sight monitoring
    • Wide area coverage
    • Fast leak detection

    Virtually Eliminate False Alarms

    Patented Harmonic Fingerprint technology verifies the presence of the target gas while rejecting interference from environmental conditions and non-target gases, helping increase operational confidence.
    • Gas-specific detection
    • Exceptional false alarm rejection
    • Reduced unnecessary shutdowns
    • Greater confidence in alarm events

    Reduce Maintenance

    Laser-based technology eliminates consumable sensors, while SimuGas™ automated self-testing reduces the need for routine manual gas checks, helping lower maintenance requirements and operating costs.
    • No consumable sensors
    • SimuGas™ automated self-testing
    • Reduced routine manual gas checks
    • Lower maintenance requirements

    Laser-Based ELDS™ Technology with Harmonic Fingerprint Detection

    The Senscient ELDS™ Open Path Gas Detector combines laser-based Enhanced Laser Diode Spectroscopy (ELDS™) with patented Harmonic Fingerprint technology to deliver highly selective gas detection while virtually eliminating nuisance false alarms.

    Unlike conventional open path technologies, ELDS™ uses tunable laser technology to detect specific target gases within a narrow section of the absorption spectrum where interference from water vapor, fog, rain, and other environmental conditions is significantly reduced. Harmonic Fingerprint processing verifies the presence of the target gas, helping improve detection accuracy and operational reliability in demanding industrial environments.

    Enhanced Laser Diode Spectroscopy (ELDS™)

    Laser-based detection technology provides highly selective monitoring of combustible and toxic gases over long distances.

    Harmonic Fingerprint Detection

    Patented multi-point verification confirms the presence of the target gas while rejecting non-target gases and common sources of interference.

    SimuGas™ Self-Testing

    Automated function testing performs daily self-checks without the need for routine manual gas checks, helping improve safety and reduce maintenance.

    Bluetooth® Connectivity

    Simplify commissioning, diagnostics, configuration, and event log retrieval using Bluetooth® connectivity and SITE software.

    Tunable Laser Technology

    Tunable lasers monitor a narrow portion of the absorption spectrum, minimizing interference from water vapor and challenging weather conditions.

    Class 1 Eye-Safe Laser

    Designed with a Class 1 eye-safe laser for safe operation while delivering reliable long-range open path gas detection.
