IKA oxygen bomb calorimeters are the market leaders when it comes to determining the calorific values of liquid and solid samples. The selection of IKA oxygen bomb calorimeters is optimally geared towards various different demands. Calorimeter portfolio includes: C 200, C 2000 and the C 5000 calorimeters. The entry level model C 200, the most cost-effective calorimeter, is easily operated manually. With a low purchase cost, the C 200 is an ideal calorimeter for learning and teaching purposes. The C 2000 offers a high level of automation along with being easy to handle. The C 5000 is the only calorimeter of its kind worldwide, combining three methods into one device. The C5000 enables users to determine adiabatic, isoperibolic, and dynamic (reduced time) calorific values. Functionality, safety, and longevity are the main goals in the development of IKA oxygen bomb calorimeters.
