Portable Oxygen Analyzer 3110P

General Details

The Model 3110 represents the new generation of portable trace and percent oxygen analysis capability. The 3110 combines a rugged, portable analyzer design with the high reliability of Teledyne trace and percent level sensors. This ensures highly accurate ppm/percent oxygen readings in a variety of background gases — including hydrocarbons. The batteries supply at least 100 hours of continuous power to the analyzer, with a low-battery indicator LED. The analyzer includes quick-disconnect fittings to take measurements without hassle and can be equipped with an external sample system. The microprocessor-based electronics provide accurate, high resolution readings and easy-to-use features.
