The APMA-370 uses cross flow modulation to measure CO in ambient air.  This involves using non-dispersive infrared (NDIR) absorption technology to measure CO in ambient air.  This method eliminates the need to adjust optical alignment and provides consistent readings.  In addition, the AS-type detector and purified reference gas eliminates interference from other elements resulting in highly accurate measurements.

The analyzer can be operated by using the interactive LCD touch-screen or a remote computer. 

An auto-range function automatically switches to the range best suited for the objects gas concentration.  Switching from auto-range to manual is simple.

Data is stored internally and can be transmitted to external devices, such as a computer, printer or other network equipment, via the system’s RS-232C serial port.  Modbus and Ethernet communication is also available.  A Compact Flash memory unit is available to collect and store data for off-line analysis and in stand-alone mode. 

The APMA-370 offers superior technology and ease of use in a sturdy, lightweight unit that fits neatly into a 19-inch rack, plus a wealth of new and upgraded features that exceed air monitoring demands.
