Heat of Combustion Testing

The 6200 Isoperibol Calorimeter is used to determine the heat of combustion of solid and liquid samples to determine and identify potentially dangerous chemical reactions. It is widely used to analyze fuels (solid or liquid), waste, and combustible samples and detects minimal energy changes with high accuracy. Our Parr™ Model 6200 ensures reliability, accuracy, and repeatability with its well-established Parr™ 1108 style oxygen bomb and compactness of the calorimeter. It features a temperature-controlled water jacket, a built-in automatic system for charging the bomb with oxygen, and a precise electronic thermometry system. The calorimeter safely burns samples up to 8,000 calories per charge, using oxygen charging pressures up to 40 atm.

Precision is a significant testing advantage. According to the manufacturer, the high level of precision is achieved through its electronic thermometer that uses a thermistor sensor specifically designed and sealed in a stainless steel probe that is located in the calorimeter cover. This advanced electronic thermometry leads to precise results even with small temperature changes. Equally as notable is its effective thermal jacking. A sealed immersion heater and a built-in heat exchanger combined with a calorimeter operated controller yields accurate jacket temperature control as it minimizes external heat changes that can alter results.

The Parr™ Model 6200 is also well-known for its efficient automatic oxygen charging system, enabling rapid testing at controlled rates to a pre-set pressure. This state-of-the-art system automatically generates its energy equivalent (EE) value from a series of standardization tests. Following the specifications by ASTM and international methods, it has 10 as the default number of tests. Parameters are easily adjustable to meet specific requirements and will generate accurate results quickly for our clients.
