AQM-103 Carbon Monoxide Monitor & Data Logger

 Supported Applications

The Omega AQM-103 is a Carbon Monoxide Monitor and Data Logger designed to measure carbon monoxide (CO) concentration, air temperature, date, and time. The device features an LCD display with keypad controls for indoor air quality (IAQ) diagnosis and HVAC system performance verification.

Operating Conditions & Performance

The AQM-103 operates within a specified ambient range of 0 to 50°C (32 to 122°F). For carbon monoxide detection, the measurement range is 0–999 ppm with a resolution of 1 ppm. The CO accuracy is ±5% of reading or ±10 ppm whichever is greater. Temperature measurements cover 0 to 50°C (32 to 122°F) with an accuracy of ±0.6°C (±1.2°F). The unit utilizes an electrochemical sensor for CO detection and requires a 1-minute warm-up time upon power-on.

Key performance characteristics include:

• CO Measurement Range: 0–999 ppm
• Temperature Accuracy: ±0.6°C / 1.2°F
• Data Logging Capacity: 32,000 points
• Update Rate: Readings update every 2 seconds
• Alarm Functionality: Audible beeper with a default CO alarm set at 30 ppm (adjustable)

Configuration Options

The AQM-103 series supports data transmission via USB, allowing for datalogging and power supply when connected to a PC. The device is powered by four AAA batteries or an optional universal AC adaptor (9V ±10%, ≥0.5A). When using the external adapter, the input voltage must be 100–240 VAC at 50–60 Hz with an output of DC 7.5–9.0 V.

Configuration and operational options include:

• Housing Dimensions: 110 H x 108 W x 28 mm D (4.33 x 4.25 x 1.10")
• Weight: 165 g (5.8 oz)
• Display Features: Large LCD showing CO level, temperature, date, and time; backlight is not available.
• Data Management: Automatic recording of maximum readings since power-on; memory clears automatically upon starting a new logging session.

Key Product Differences

The primary model in this series is the AQM-103, described as a CO monitor and data logger. An optional accessory, the AC adaptor (model AQM-100-PW), provides external power capability. The device carries CE certification.
