AC600 Semi-Automatic Isoperibol Calorimeter

Calor
main-AC600

Test vessel

LECO calorific vessel has reduced weight, rounded shape, with cap secured within 1.5 revolutions. It optimizes heat transfer rate and easy handling for quicker vessel preparation.

Description

The calorific value is one of the most important quality parameter of solid fuels, like coal, coke and biomass as well as waste materials. Calorific value of a sample is determined by precisely measuring the heat released after combustion of the sample in a controlled environment. The heat released is proportional to the calorific value of the substance.

The LECO AC600 semi-automatic isoperebol calorimeter sets the standard for future calorimetry instruments and was developed to measure the calorific content of various organic materials such as coal, coke, biomass and fuel oil.. 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, integrated vessel charging station offer convenient operation while greatly reducing operator strain.

Windows®-based operating system allows settings of all test parameters including special required ASTM or DIN calculations and corrections.

 

Benefits:

  • Fastest calorimeter with 5.5-minute analysis times without compromising accuracy or precision
  • Automated features and ergonomic design enhance productivity
  • Integrated vessel charging station and quick-release handles simplify operation

Operation

Two operational Modes for calculating results are available. In standard DeltaT Mode the simple temperature difference calculation for calorific values determined by a simple maximum temperature rise of the bucket. The advanced TruSpeed Mode is based on a unique thermodynamic model developed by LECO that takes into account heat capacities of the system’s components along with corrections for energy transfer within the system. The TruSpeedTM mode enables the AC600 to attain rapid 5.0 minute analysis times without compromising the accuracy or precision of the calorific result. Optional two-vessel operation maximizes throughput allowing you to prepare the second vessel and sample while the current sample is being analyzed.

 Features:

  • Reduced vessel weight with rounded surfaces promotes easy handling of the vessel, while enhancing the heat transfer rate of the vessel
  • Each vessel has engraved serial number for traceability
  • All water filling, draining, and volume measurement, as well as control of the addition of heating and cooling water, are automatically handled within the instrument
  • User-defined calculations support custom calculations or conversions for data and results.
  • •Thermochemical basis corrections for: Fuse, Nitrogen, Sulfur, Spike, and Ash.
