- Model ANDROS 6552 - OEM Gas Analyzer



Advanced Energy’s Andros 6552 gas analyzer is available with two gas channels and can be applied to any type or combination of refrigeration systems that employ FreonsTM and carbon dioxide. Ability to measure up to five gases. Rapid warm-up. Highly accurate calibration. Simple and fast system integration. RS232 or USB communications.

The Andros® 6552 gas analyzer / non-dispersive infrared (NDIR) sensor is individually calibrated for operation from 0 to 50°C over the range of specified concentrations. Results are stored within each system to provide accurate analysis. It’s designed to meet or exceed the EN 14624 standard for performance of mobile leak detectors and room controllers of halogenated refrigerants.

You can also benefit from greater design flexibility thanks to the 6552’s small size and low power consumption. And it’s operating system simplifies system integration.
