Our comprehensive solutions for improving productivity include working with you to find the right equipment for the type of analysis you are doing — and providing you with the training, application support, and service you need to keep your lab running at its best.

AC500 Isoperibol Calorimeter for Gross Calorific Content
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 the 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.
