A self-contained oxygen bomb calorimeter with automatic microprocessor control, for rapid and precise calorific tests with minimal operator attention. Excellent repeatability using either the classical equilibrium method, or a rapid dynamic method which reduce test time to 3 or 4 minutes after firing. The 6200 has a built-in automatic system for filling the bomb with oxygen. Temperatures are measured with a high precision electronic thermometer. A circulating water system maintains a forced flow around the bucket chamber. All steps in the test procedure are managed by a microprocessor control system. The LED display prompts the operator, gives status indication, data verification and report review. Includes six fuel capsules, fuse wire, 1108 oxygen bomb, and benzoic acid pellets. For 110V, 60 Hz.
