Key Features of Andros 6552 Gas Analyzer

OEM gas sensor detects Freon refrigerants and Carbon Dioxide for leak detection and other applications

  • Measure up to 5 gases: 3 via NDIR and 2 via plug-in sensors
  • RS232 or USB
  • Most types of Freons
  • Field upgradable to measure additional gases


Benefits of Andros 6552 Gas Analyzer

Highly Accurate Calibration

Every Andros 6552 system is individually calibrated for operation from 0°C to 50°C over the entire range of specified concentrations. The results of this intensive calibration process are stored within each system providing the most accurate analysis possible. This attention to detail provides a highly accurate factory calibration of the NDIR analyzer. Andros is so confident in our factory calibration that our customers need never calibrate the NDIR analyzer again.

The Andros 6552 is designed to meet or exceed EN 14624,“performance of mobile leak detectors and of room controllers of halogenated refrigerants”.

High Stability: Rapid Warm-Up

The enhanced optics and electronics of the 6552 have virtually eliminated zero drift after the initial warm up period. The temperature and pressure compensation eliminates the major causes of span drift in many NDIR instruments.

Unique Optical Architecture

The Andros 6550 Series offers greater design flexibility to OEMs due to its small overall size, our ability to customize subsystem designs to your specifications, and low power consumption. Our analyzer can be fitted into a wide variety of enclosures.

Comprehensive Software Architecture

The Andros Operating System (OS) software and communications protocol is designed to make system integration simple and fast.
