Open Path Gas Detector Simultaneously Detects Methane and Hydrogen Sulfide Gas

Senscient’s ELDS Series 2000 H2S+CH4 open path gas detector (OPGDs) features the company’s Enhanced Laser Diode Spectroscopy (ELDS) technology for increased sensitivity, simultaneous multi-gas detection capability and remote electronic functionality confirmation. Senscient’s ELDS Series Open Path Gas Detectors (OPGDs) feature false-alarm free, low ppm detection of both flammable and toxic gases.

Using a separate transmitter and receiver configuration, ELDS Series 2000 dual laser systems measure a Harmonic Fingerprint introduced onto the transmitter’s laser beams by absorption of the target gases in the monitored path. It is the Harmonic Fingerprint technology combined with other features that enable ELDS detectors to eliminate false alarms from non-target gases such as organic surfactants, diesel fumes, oil mist and other environmental factors such as rain and snow that bedevil other gas detectors in the market.

The ELDS OPGD detectors also feature SimuGas, a remote detector testing and auto data-logging technology that eliminates the need to physically access individual gas detectors in the field or handle hazardous gas cylinders to perform functional testing.

Senscient’s ELDS OPGD gas detectors are the only open path detectors with both FM Global and ATEX Electrical Safety Approvals and Performance Certifications. ELDS Series detectors meet and exceed the requirements of the leading gas detection safety standards for offshore oil drilling platforms, FPSO’s, onshore petrochemical facilities and oil refineries around the world.
