- Model TDLAS 5100 - Gas Analyzer

From

0

The Model 5100 hosts a single laser platform to measure a single gas analyte. The Model 5100 can measure any one of the following gas analytes: water vapor, methane, hydrogen sulfide, carbon dioxide, and oxygen in process or flue gas. If water vapor is the measured gas analyte, methane can be monitored additionally at percent levels using the same laser.

The Model 5100 is designed to handle sample gases with dew points as high as 55ºC. For higher temperature dewpoint applications the Model 5100HD is recommended.

A key feature of the Model 5100 is the use of a sealed reference cell, which contains a known amount of analyte gas measured, for referencing the emission wavelength of the laser. The use of a reference cell enables both the ability to line-lock the lasers and to continuously verify the instrument calibration.

Model 5100 offers high specificity, selectivity, speed of response and great reliability.
