ATEX-certified multi-gas detector for hazardous areas and emergency response
Esders GOLIATH is a professional gas detection instrument developed for gas utilities, emergency services, industrial maintenance teams, and contractors working in potentially explosive environments.
Certified according to ATEX Ex II 2G, GOLIATH can be safely used in hazardous areas where conventional electronic instruments are not permitted. It combines natural gas leak detection, pressure measurement, multi-gas monitoring, and safety inspections into one compact and robust device.
Designed for hazardous environments
Safety is critical when working with combustible gases. GOLIATH is specifically designed for operation in explosive atmospheres, making it ideal for:
- Natural gas distribution networks
- Gas pressure regulating stations
- Industrial plants
- Boiler rooms
- Commercial and residential buildings
- Underground utility chambers
- Emergency response operations
Its rugged IP54 housing and ATEX certification ensure safe and reliable performance in demanding environments.
One instrument – multiple applications
GOLIATH is far more than a conventional gas detector.
It enables:
- Natural gas leak detection and pinpointing
- Building gas safety inspections
- Pressure testing up to 2,000 hPa
- Confined space gas monitoring
- Carbon monoxide monitoring
- Oxygen measurement
- Carbon dioxide monitoring
- Optional H₂S and additional toxic gas measurements
- Gas pipe commissioning and purging
- Pipeline filling velocity measurement (optional)
Multi-gas monitoring
Depending on the configuration, GOLIATH can simultaneously measure:
- Methane (CH₄)
- Propane (C₃H₈)
- Carbon monoxide (CO)
- Carbon dioxide (CO₂)
- Oxygen (O₂)
- Hydrogen sulphide (H₂S)
An optional ethane analysis module allows operators to quickly distinguish natural gas from biogas, reducing unnecessary excavation work and improving inspection efficiency.
Built for emergency services
GOLIATH is particularly suited for emergency response operations where technicians must quickly determine whether a reported gas odour represents an actual leak or another problem.
It also continuously monitors carbon monoxide during building inspections, providing an early warning of possible flue gas or ventilation failures.
