JT33 TDLAS gas analyzer

Brand: Endress+Hauser
Request Information

The JT33 gas analyzer offers continuous, real-time H2S measurement with low maintenance requirements. It enables plant operators and owners to meet gas quality standards, improve process control, and ensure asset integrity. Using proven differential technology, the JT33 tolerates stream changes while meeting measurement performance specifications. It also features auto-validation and advanced diagnostics supported by Heartbeat Technology for verification reporting.

 

  • Natural gas, biomethane, and carbon dioxide pipelines: prevent corrosion and minimize the risk of an uncontrollable event, ensuring asset integrity

  • Natural gas and LNG plants: optimize gas sweetening processes (amine, solid scavengers, and others)

  • NGL, refining, and petrochemical gas streams: assure gas quality and asset protection in fractionization, refining, and stream cracking processes

  • Carbon capture processes (CCUS): monitor processes and ensure that CO2 meets quality specifications

Features

  • Continuous, real-time TDLAS measurements with proven metrology to meet measurement specifications

  • Robust patented differential technology which tolerates contaminants and stream changes in tough applications

  • Auto-validation to confirm analyzer health in the field

  • Heartbeat Technology for automatically stored historical data, spectrum logging, diagnostics, and verification reporting for custody transfer applications

  • NIST-traceable factory calibration with superior accuracy and repeatability

  • Field-serviceable components and modules for minimal downtime and maximum repair flexibility

  • User-friendly interface with an intuitive menu and integrated web server software
