Test Results of the Solid State Stand Alone Developmental Calorimeter

EG&G Mound Applied Technologies has developed a stand alone developmental calorimeter which utilizes solid state sensor technology. The sample size was increased to 8 in. high by 4 in. diameter in the system under test from 3 in. high by 5/8 in. diameter in the previous prototype. The calorimeter system uses an air bath for environmental stability which further reduces weight and assay time. Tests in the developmental system have produced excellent servo control results over the 0.5 to 5 watt range, with one sigma precision errors ranging from 1.3% at 0.5 watts to 0.1% at 4 watts. The average run time of these samples was approximately 90 minutes with no preconditioning used.
