Calorimeter Models​

	Model 7400 Automatic Isoperibol Calorimeter The new 7400 Automatic Isoperibol Calorimeter is Parr’s fastest and most automated calorimeter. It features a fixed vessel-and-bucket design, a 10-inch adjustable touchscreen, upgraded processing power, a closed-loop cooling subsystem, and Quick Twist-Lock vessel closure to improve ease of use, speed, and reliability. The 7400 requires only one minute of operator time per test, allowing a technician to operate up to four calorimeters simultaneously.
	Model 7200 Precision Isoperibol Calorimeter Parr’s new 7200 Precision Isoperibol Calorimeter is our most precise model, designed for high-precision quality control work and R&D. Its traditional removable vessel-and-bucket design and water jacket give users full control over the combustion process. With a slimmer 17-inch (43 cm) footprint, upgraded processing power, modern software, and a 10-inch adjustable touchscreen, the 7200 delivers trusted Parr accuracy in an efficient, user-friendly design.
	Model 6100 Compensated Jacket Calorimeter The Parr 6100 Compensated Calorimeter takes advantage of the real time, continuously corrected method originally developed by Parr Instrument Company. This real time correction can produce superior results. This feature will make it attractive for coal testing, waste and refuse disposal work, and other sample testing.
	Model 6050 Compensated Jacket Calorimeter This new calorimeter is the first designed by Parr to be controlled by your own personal computer allowing access to the calorimeter’s functions and tests. This moderately priced, compact calorimeter combines a static jacket system with the convenience of automated oxygen filling.
	Model 1341 Plain Jacket Calorimeter A reliable calorimeter, the 1341 can be used for the same broad range of solid and liquid combustible samples as our other more advanced calorimeters. Its modest cost and simple design make the model suitable for low throughput and minimal precision work such as sample screening and student instruction.
	Model 6725 Semimicro Calorimeter The 6725 Semimicro Calorimeter is a compact, static jacket, calorimeter designed specifically for measuring the heat produced by the combustion of small samples. The small sample capacity is ideal for marine biology research as well as other applications where the available sample is limited.
	Model 6755 Solution Calorimeter The 6755 Solution Calorimeter is designed for laboratories who wish to measure enthalpy changes produced by chemical reactions in solution.
	Model 6765 Combination Calorimeter The 6765 Combination Calorimeter provides all of the equipment for running both solution calorimetry and semimicro oxygen bomb calorimetric tests.  This is a valuable multi experiment system for physical chemistry instruction.  Conversion sets are also available to add the second operating mode to either the 6725 Semimicro Calorimeter or the 6755 Solution Calorimeter.
	6772 Calorimetric Thermometer The 6772 Calorimetric Thermometer High precision temperature measuring system is designed for use with 1341, 6725 and 6755 Model Calorimeters. Includes an ignition firing system and stirrer motor output.
	6790 Detonation Calorimeter The Parr Detonation Calorimeter is designed to measure the heat of detonation to aid research in the area of high explosives performance. Sample sizes of up to 20 grams can be accommodated in the specially designed spherical combustion chamber.
