Semi Automatic Calorimeter for Oil Fuel and Petroleum Testing Instruments

The Isoperibolic Oxygen Bomb Calorimeter determines the heat of combustion of a weighed sample by burning it in an oxygen pressure vessel under controlled conditions. The heat of combustion is calculated from temperature measurements taken before, during, and after combustion, with appropriate thermochemical and heat-transfer corrections. The instrument features a removable oxygen pressure vessel and bucket for convenient sample loading and water filling. A controlled-temperature jacket surrounds the combustion vessel and bucket, while a microprocessor-based controller monitors both temperatures and continuously applies real-time heat-leak corrections. Designed for high-precision quality control, research, and development applications, the system supports multiple pressure vessel configurations for different energy release requirements. Manufactured by Atico Export with a focus on precision, durability, and reliable performance for calorific value and combustion testing applications.
