2185 



2185 CALORIMETER, Emerson's, one of the most modern bomb calorimeters for 

 determining the heating value of solid and liquid fuels. 



The Bomb is made of steel, consisting of two cups joined by 

 means of a heavy steel nut. The lining is of sheet metal, spun to fit 

 the interior. The pan holding the combustible is usually of nickel 

 and so are the supporting wires. The fuse wire for general fuel 

 testing should be of platinum. 



The Calorimeter jacket is a double walled copper tank. The 

 calorimeter bucket is of light sheet brass. 



The Stirring Device consists of a propeller fitted shaft inclosed 

 in a vertical tube to facilitate its action in circulating the water. The 

 stirrer is mounted on a post on the calorimeter jacket as is the 

 thermometer holder. The motor is driven by a 110-volt circuit and 

 should be placed in series with a 16 C. P. lamp. If so desired, a 

 battery driven motor can be specified in ordering the apparatus. 



The Oxygen Piping is especially strong and durable and is 

 designed for two cylinders. Other accessories such as iron plate 

 holder, swivel table, spanner or wrench are furnished with the outfit. 



A pamphlet describing the instrument fully may be had upon 

 application.
