Teledyne-API Model 300EM
Gas Correlation CO Analyzer

The Model 300EM measures carbon monoxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. This is accomplished with a Gas Filter wheel which alternately allows a high energy light source to pass through a CO filled chamber and a chamber with no CO present. The light then travels through the folded path sample cell. This technique allows near interferent free operation.

The M300EM design produces superior zero and span stability and a high signal-to-noise ratio, allowing excellent sensitivity.

Multi-tasking software gives real time indication of numerous operating parameters and provides automatic alarms if diagnostic limits are exceeded. Built-in data acquisition and internal memory allows logging multiple parameters including average and instantaneous values, calibration data, and operating parameters. Stored data can be retrieved via the RS-232 port, optional Ethernet port, or from the front panel.

The Model 300EM features rugged construction and is designed to perform with a minimum of attention. Regular maintenance is greatly simplified through the use of modularized construction.
