Parr 1261EA Isoperibol Calorimeter

The Parr 1261 oxygen combustion bomb calorimeter has been designed to provide rapid and reliable heat of combustion values for solid and liquid fuels. This instrument combines third generation microprocessor hardware and software with the calorimeter designs and technical knowledge.

In isoperibol operation, the calorimeter jacket is held at a constant temperature while heat from the burning sample causes the bomb and bucket temperature to rise. The small heat flow between the bucket and its surroundings during a test is monitored by a microprocessor in the calorimeter, which continuously determines the effect of any heat leak and applies the necessary correction automatically.

This Parr 1261 calorimeter appears to be in working order and comes as seen in photos only - bomb/vessel is not included.
