hydrogen sulfide analyzer / methane / oxygen / carbon dioxide
5100 AMETEK Process Instruments



  • Measured entity:

    gas, oxygen, carbon dioxide, methane, hydrogen sulfide

  • Measured value:


  • Configuration:

    for integration

  • Other characteristics:

    online, real-time, tunable diode laser technology, process


The 5100 hosts a single laser platform to measure a single gas analyte. The device 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 5100 is designed to handle sample gases with dew points as high as 55ºC. For higher temperature dew point applications the 5100HD is recommended.


All digital signal processing
Web-based interface
Connectivity by modbus, ethernet and analog
Real-time performance monitoring
Fully integrated sample handling
Resistant to contamination
Reference Cell enables Line Lock and Span Verification
A key feature of the 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.

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