Edgetech - Model AM507 -Inline Oxygen Analyzer

SHARE

The AmO2xys (AM507) is a compact inline oxygen analyzer designed for continuous, real-time oxygen measurement in critical gas processes. Supporting both trace (PPM) and percent (0–100%) oxygen ranges, this flexible analyzer is ideal for applications requiring high accuracy, low maintenance, and seamless integration. The AM507 is available in flow-through or KF-40 direct-fit configurations, with output options ranging from basic 2-wire loop power to fully “smart” RS485 Modbus communication.

Versatile Measurement Range

Measure trace oxygen (PPM) or percent levels (up to 100%) with one compact analyzer—ideal for dynamic or changing process conditions

Direct Inline Installation

Available in flow-through or direct KF-40 configurations for easy integration into gloveboxes, process lines, or lab systems. 

Smart Output Flexibility

Supports multiple output types including 2-wire loop power, 3-wire isolated 4–20 mA, 0–10 VDC, and RS485 Modbus. Choose the version that fits your system.

Low Maintenance, Long Sensor Life

No electrodes to clean or electrolyte to refill. Sensors offer long life (20–25 months) and excellent performance in inert and acid gas environments.

Compact, Rugged Enclosure

Durable anodized aluminum housing measures just 6.3" x 3.5", making it ideal for space-limited installations and field conditions.
