EAGLE 2 Gas Monitor Overview and Safety

Operation and Safety Warnings

• Understand the manual before operating the EAGLE 2 gas monitor.
• Substitution of components may impair the device's intrinsic safety.
• Battery changes or charging must only occur in nonhazardous areas to prevent ignition risks.
• Not tested for use in oxygen-enriched environments (above 21% concentration).
• Refer to ISA-RP12.13, Part II-1987 or similar guides for combustible gas detection instrument usage.

EAGLE 2 Overview

• The EAGLE 2 gas monitor features an advanced detection system with up to six sensors.
• Capable of detecting combustible gas, oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), and other toxic gases simultaneously.
• Designed for various applications, including sewage treatment, utility manholes, tunnels, hazardous waste sites, power stations, petrochemical refineries, mines, paper mills, drilling rigs, and firefighting.

Features of the EAGLE 2

• Monitors one to six gases concurrently; the standard configuration includes four sensors for combustible gases, oxygen, CO, and H2S.
• Offers three operating modes: Normal Mode for typical confined space monitoring, with a factory-default setting.
• Rugged design with comfortable handle, LCD window, and removable battery case.
• Gasketed interfaces enhance safety and functionality.
• Raised feet design ensures stability during operation.

Sensor Functionality

• EAGLE 2 utilizes up to six sensors located within the bottom case for gas monitoring.
• Standard sensors include several types: PID sensors, ESM-01 toxic sensors, TC sensors, and infrared sensors for CO2, methane, and hydrocarbons.

Catalytic Combustible Gas Sensor

• The catalytic combustible gas (LEL) sensor detects combustible gases in the %LEL range.
• Operates by measuring changes in resistance due to gas reacting with oxygen on a catalyst.
• Current changes are amplified, converted to concentration measurements, and displayed on the LCD.
• Features a sintered metal flame arrestor for safe gas diffusion into the sensor.

Hazard Warnings and Sensor Care

• Caution against exposing the catalytic sensor to high concentrations of combustible gases, which can damage the sensor and affect performance.
• Rapid increases in gas readings may indicate dangerous gas concentration levels.
• Specific gases can contaminate the sensor, degrading its ability to detect combustible gases effectively.

Detection Range and Settings

• EAGLE 2 allows users to switch detection units of the catalytic combustible channel between %LEL, ppm, and %volume using the RANGE ▼ SHIFT button.
• Detection range corresponds to 0-100% LEL for the configured gas—for example, methane’s (CH4) LEL is 5% volume or 50,000 ppm.
