OEM Gas Analyzer ANDROS 6511

OEM Gas Analyzer for Greenhouse Gas Detection and Monitoring

The Andros 6511 offers unparalleled accuracy and performance. Now taking advantage of the latest technology, Andros brings you a product with superior performance and reliability.

The Non-Dispersive InfraRed (NDIR) sensor can measure the greenhouse gases CO2 and Methane via RS-232 communications with the host.

Benefits of the Andros 6511 NDIR Bench

Highly Accurate Calibration

Every Andros 6511 NDIR bench 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 6511 is designed to meet and exceed performance requirements for portable or fixed leak detectors of toxics or combustibles.

High Stability: rapid warm-up

The enhanced optics and electronics of the 6511 has virtually eliminated zero drift after the initial warm up period.

Prior to this breakthrough, frequent zeroing of an analyzer was often required during the first half-hour of operation for the most sensitive measurements. Now, with just two “zeroes” during the first three minutes, the new Andros 6511 is ready to meet all accuracy specifications.


Unique Optical Architecture

The Andros 6511 optics incorporates precision beam collimating architecture.

A concentrated infrared beam generated from a proprietary emitter, passes through a precision lens into a cleanable or replaceable gold-lined sample cell that the gas of interest is flowing through.

The beam then passes into an optical assembly of highly specialized filters and a unique multi-element detector.

Comprehensive Software Architecture

The 6511 embedded Operating System (OS) software has been developed to provide our customers the means to tailor a number of operations in the 6511 without the need for a custom OS. All calculations are performed in real time for transmission to your host system.
