AC500 Isoperibol Calorimeter from LECO Corporation

This manual, bench-top, stand-alone unit uses a fully integrated circulation system that gives a compact footprint while being simple to operate with Windows®-based software. The AC500 has an integral water-measuring and combustion vessel-filling station that simplifies sample preparation, without additional heaters or coolers. An electronic thermometer accurate to 0.0001°C measures the temperature of the water every six seconds. The AC500 also has the unique ability to constantly monitor temperature in both the outer jacket and the calorimeter proper, making two-channel correction possible.
