Leco - Calorific Value

The Leco calorimeter determines calorific value, a key indicator of quality and value in solid and liquid fuels, through measurement of the heat released after combustion of a sample. They have rapid analysis of calorific content and increased instrument throughput without sacrificing accuracy or instrument precision.

Available models

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)

The AC500 determines calorific value, a key indicator of quality and value in solid and liquid fuels, through measurement of the heat released after combustion of a sample. This stand-alone benchtop unit uses a fully-integrated circulation system for a compact footprint—no additional heaters or coolers required. An integral water-measuring station simplifies sample preparation, and a Windows®-based operating system uses an electronic thermometer accurate to 0.0001°C to measure temperature every six seconds. Two-channel correction is possible through constant temperature monitoring in both the outer jacket and the calorimeter proper.

  • High precision across a wide range of sample sizes and ambient conditions
  • Fuse wire or string-ignition combustion vessel
  • Several analysis modes available: Regnault-Pfaundler, Precision, and Predictive
