ETA900 Smart Landfill Gas Detector
Product Overview
The ETA900 Smart Landfill Gas Detector is a highly configurable portable multi-gas monitoring instrument specifically designed for landfill gas detection, environmental monitoring, industrial hygiene, confined space inspection, and workplace safety applications.
The detector can simultaneously integrate up to four gas sensors, including an advanced NDIR CO₂ sensor, making it one of the few portable gas analyzers capable of monitoring CO₂, methane (CH₄), oxygen (O₂), hydrogen sulfide (H₂S), combustible gases, and toxic gases in a single device. The ETA900 also measures temperature and humidity for comprehensive environmental assessment.
Equipped with a built-in sampling pump, color touch screen, data storage, USB communication, and audible/visual alarms, the ETA900 provides reliable and efficient gas monitoring in demanding field conditions.

Key Features
• Simultaneous monitoring of up to 4 gases
• Supports CO₂, CH₄, O₂, H₂S, combustible gases, and toxic gases
• Advanced NDIR infrared CO₂ sensor technology
• Built-in sampling pump for remote gas sampling over tens of meters
• Real-time temperature and humidity monitoring
• Large color touch screen for intuitive operation
• Data storage capacity of up to 256 records
• USB interface for data transfer and PC connection
• Automatic unit conversion between ppm and mg/m³
• Audible and visual alarm system
• Automatic self-test of display, battery, sensors, and alarms
• Long operating time of approximately 200 hours per charge
• Flexible sensor configuration for different industries

Working Principle
The ETA900 continuously draws air samples through its built-in pump and analyzes gas concentrations using a combination of electrochemical, catalytic, PID, and infrared sensing technologies depending on the selected sensor configuration.
The NDIR sensor accurately measures carbon dioxide concentrations, while dedicated gas sensors monitor oxygen, methane, hydrogen sulfide, combustible gases, and other toxic gases. The instrument processes sensor signals in real time and displays concentration values, temperature, and humidity on the touch screen. When gas levels exceed preset alarm thresholds, audible and visual alarms are activated immediately.
