Using tunable diode laser absorption spectroscopy, the 5100P is a transportable, easy-to-use analyzer optimized to measure either water vapor (H₂O) or carbon dioxide (CO₂) in select gas streams. It offers the fast-response, high-accuracy benefits of TDLAS technology in a lightweight, durable and mobile platform that is certified for use in hazardous areas including Class I, Division 2, and both ATEX and IECEx Zone 2. With an integrated sample system, the 5100P is fast and easy to use – simply connect the sample tubing, power up the analyzer and begin the sample gas flow through the system. As the tool of choice for users needing to perform measurements in remote locations, or verify fixed analyzer installations, the 5100P is designed to monitor H₂O and CO₂ in natural gas and other select applications. Non-contact sensing technology keeps both the laser source and detector separate from the process. This eliminates the need for routine calibration, sensor cleaning, or interferences from process contaminants, increasing measurement uptime and reducing total cost of ownership.Every 5100P is factory calibrated and tested prior to shipment. It also uses an internal reference to prevent any wavelength shift when operated in the field. Line-locking monitors and controls the laser source output continuously to ensure an accurate measurement. TDLAS technology delivers an immediate response to changes in the H₂O or CO₂ content of the sampled gas, without a delay waiting for the sensor to equilibrate. This allows more measurements to be made in less time. The 5100P is a moveable TDLAS solution for measurements of moisture or carbon dioxide in select gas streams.
