2193 CALORIMETER Sargent's, for gas: The only apparatus conforming with the 

 suggestions of American authorities, being the most advanced type of instru- 

 ment for testing the thermal value of inflammable gases. It has the following 

 advantages: 



(1) The discharge water is weighed to one-hundredth of a pound instead 

 of being measured in a graduate. (2) The discharge water is switched auto- 

 matically from one receptacle to another after each one-tenth of a cubic foot 

 of gas is burned. This eliminates errors due to hand manipulation. (3) Inlet 

 and outlet thermometers are on the same level so that they can be read almost 

 simultaneously. (4) A Wet Pressure Governor controls the pressure of the 

 gas entering the burner and a constant pressure is easily maintained by means 

 of adjustable weights. (5) To maintain a constant flow the inlet and outlet 

 pipes are provided with wiers. A graduated quadrant valve regulates the 

 amount of water used. (6) Since a determination can be made every three or 

 four minutes, a curve of the heat value extending over any length of time may 

 be plotted. (7) The heat value of the gas is determined directly in B. T. U. 

 (8) The Bunsen burner has two tips and is adjustable for gas having 100 to 

 1500 B. T. U. per cubic foot. (9) The calorimeter is made of copper and brass 

 and is handsomely nickel-plated. (10) The Wet Test Gas Meter is made of 

 heavy brass and tin and has a water level indicator outside of the gauge glass. 

 The meter is graduated to 0.001 cubic foot. 



The complete outfit consists of the first six items below.
