Description

The ABSOLUTE API4380-G is a rugged, intrinsically safe, portable multi-gas detector engineered for personal and area monitoring in hazardous industrial environments. Designed to simultaneously detect up to four critical gases—including oxygen (O₂), combustibles (LEL), carbon monoxide (CO), and hydrogen sulfide (H₂S)—it delivers fast response, long-life sensors, and intuitive operation for worker protection in oil & gas, utilities, wastewater, and confined space entry applications.

Certified for global hazardous area use and built to withstand harsh conditions, the API4380-G combines reliability, ease of maintenance, and compliance with OSHA, NFPA, and IECEx standards—making it a trusted frontline defense against toxic exposure, asphyxiation, and explosion risks.

Application Scenarios

During a routine tank cleaning operation at a U.S. refinery, a crew entered a storage vessel assuming ventilation had purged all hazards. Within minutes, H₂S levels spiked to 120 ppm—well above the 10 ppm STEL limit. Thanks to the ABSOLUTE API4380-G worn by the attendant, an immediate audible and visual alarm triggered, prompting evacuation before symptoms appeared. Post-incident analysis confirmed the detector’s electrochemical H₂S sensor responded in under 15 seconds. “That device didn’t just warn us—it saved careers,” said the site safety manager. In life-threatening environments, the API4380-G turns invisible threats into actionable alerts.

Technical Principles and Innovative Values

Innovation Point 1: Smart Sensor Auto-Recognition

The API4380-G automatically detects and configures new sensor cartridges upon insertion—eliminating manual calibration setup errors. Each sensor contains a memory chip storing its type, serial number, and calibration due date, streamlining compliance tracking.

Innovation Point 2: Pump-Assisted Sampling (Optional)

With the integrated sample pump (model variant API4380-G-P), the unit can draw air from up to 30 meters away—ideal for pre-entry testing of sewers, silos, or tanks without direct exposure.

Innovation Point 3: Rapid Bump Test & Calibration

Using Absolute’s QuickCal™ system, users perform full functional verification in under 30 seconds with a single-button test. Automated calibration reduces technician training time and ensures regulatory readiness.

Innovation Point 4: Ruggedized for Real-World Abuse

Encased in high-impact polycarbonate with reinforced corners, the API4380-G survives 2-meter drops onto concrete. Its IP67 rating ensures reliable operation in rain, mud, or high-humidity environments—common in offshore and mining sites.

Application Cases and Industry Value

Wastewater Treatment Plant (Germany):

Workers routinely enter lift stations with unknown H₂S levels. Since deploying API4380-G units with pump kits, zero confined-space incidents have occurred over 18 months. Maintenance teams now log every pre-entry test digitally—satisfying DGUV regulations effortlessly.

Offshore Oil Platform (Gulf of Mexico):

The API4380-G’s resistance to salt spray and wide temperature range made it the replacement for older detectors that failed during tropical storms. Its 24-hour runtime covers full shift rotations without recharging—critical on remote installations.

Chemical Distribution Terminal (Singapore):

During ammonia unloading, a minor leak went undetected by fixed systems due to wind direction. A technician’s API4380-G triggered an alarm at 25 ppm, initiating emergency isolation. The event was later used in safety training to highlight the value of personal monitors.
