Andros Gas Analyzers


OEM Gas Analyzers to Detect and Monitor Greenhouse Gas, Freon Refrigerants, Carbon Dioxide and Auto Emissions

Advanced Energy’s Andros series non-dispersive infrared (NDIR) gas sensors achieve high accuracy with high reliability without requiring limited-lifetime moving components used by alternative analyzers. Featuring host communication via RS232 and USB and enhanced optics and electronics to eliminate zero drift, the sensors measure up to five gasses, three via NDIR and two via plug-in sensors. The series comprises several models, including the ISO 3930/OIML R99, Class 0, and BAR 97 compliant 6500 and 6520, the 6511 for CO, CO2, and CH4 measurements in various industrial, agricultural, and power generation applications, as well as the EN 14624 compliant 65552 that finds typical use in refrigerant leak detection. All sensors are factory calibrated at four temperatures between 0°C and 50°C, each with 20 gas concentrations.
