Semi-Automatic Isoperibol Calorimeter

Gross Calorific Content

Developed to measure the calorific content of solid and liquid fuels, the LECO AC600 semi-automatic isoperibol calorimeter sets the standard for future calorimetry instruments. Its semi-automated operation, combined with the use of thermodynamic TruSpeed®, obtains a rapid analysis of calorific content and increased instrument throughput without sacrificing accuracy or instrument precision. A new, ergonomically-designed, lightweight combustion vessel assures ease of operation while greatly reducing operator strain.



  • Automated features enhance productivity
  • 5.5-minute analysis times possible, without compromising accuracy or precision
  • Integrated vessel charging station and depressurization ports equipped with quick-release handles to speed vessel charging and depressurization process
  • Intuitive Windows®-based software provides virtually unlimited storage space, simplified data handling, and compatibility with various Laboratory Information Management Systems (LIMS)


Ergonomically-Designed Vessel

Reduced vessel weight with rounded surfaces promotes easy handling of the vessel, while enhancing the heat transfer rate of the vessel. The vessel cap secures within 1.5 revolutions, greatly reducing repetitive motion and allowing for quicker vessel preparation. Simple and clean electrical contact and oxygen depressurization port reduce oxygen and thermal leak points, improve accessibility of rinsing vessel, and decrease overall points of maintenance within the vessel.
