54.928. Indicator for stationary use, cf. Fig. 54,929 A and B, for Resistance Thermometer 

 NOs. 54,923/6, consisting of a pointer galvanometer and a slate slab with switching 

 and regulating devices for one range from 300 to 700 C., with one lead, without lead 

 mountings . '. . 



The minimum range can be selected for 200 to + 100 or for 100 to 0, or for to + 150. 

 for + 100 to + 300, for + 200 to + 500,tor + 300 to + 700. 



It specially desired the indicating apparatus is supplied for still smaller ranges (say. .'ill to 4u") 

 at an extra price. 



The range desired should be quoted when ordering. 



It is advisable to order at the same time the connecting leads (double stranded copper) lieiween 

 the thermometers and the indicating apparatus, in order that their resistance can be taken into account 

 in calibrating. See No. 54,940.
