FIG. 24. Type of Babcock turbine testers (for 

 testing cream in9-in. cream bottles). 



samples contain- 

 ing less than one- 

 tenth per cent, 

 fat. Some of 

 the most recent 

 makes of turbine 

 testers are pro- 

 vided with holes 

 in the covers and 

 dampers. A ther- 

 mometer is also 

 placed in the 

 cover. 

 Babcock testers 



run by electricity have lately been put 

 on the market by a couple of manu- 

 facturers (fig. 23). Where no steam, 

 but electrical current is available, these 

 machines may be in- 

 stalled to great advan- 

 tage, as they are con- 

 venient to use and may 

 be depend* d on to run 

 at the required speed. 

 Some provision for get- 

 ting hot water must be 

 at hand in using elec- 

 trical Babcock testers/
