Introduction
The PureAire Dual O2/CO2 Monitor is a compact gas monitoring system designed for continuous monitoring of oxygen and carbon dioxide levels. It is ideal for ensuring safety in areas with potentially low oxygen or high carbon dioxide concentrations, such as inert gas storage areas and confined spaces.
This monitor utilizes a long-lasting zirconium oxide sensor for oxygen detection and a patented NDIR sensor for carbon dioxide. These sensors provide stable and accurate readings across a wide range of temperatures and humidity levels. The system is suitable for both indoor and outdoor use and is factory calibrated against NIST traceable standards.
The PureAire Dual O2/CO2 Monitor can be used as a standalone unit, linked to PureAire controllers, or integrated into existing centralized control systems. This manual provides comprehensive guidance on the installation, operation, and maintenance of the monitor.
Key Features
- Long Life Zirconium Oxide O2 Sensor: Offers over 10 years of continuous operation without needing a reference gas.
- NDIR CO2 IR Sensor: Features a fast-responding sensor with an automatic calibration feature that adjusts every 180 hours.
- Smart Electronics: Continuously monitors sensor operation and alerts users to potential faults.
- Calibration: The O2 sensor requires minimal calibration, with verification against ambient oxygen levels. The CO2 sensor has automatic baseline adjustments, with manual adjustments available if needed.
Component Identification
The monitor features a digital display, joystick for menu navigation, cable port for power and output connections, and various sensors and indicators. Key components include the Oxygen Sensor, CO2 Sensor, Sensor Protector, Alarm Indicators (LEDs), and an Audio Horn.
