NEW TEMCOMETER Temperature
Controller
and
Indicator
T h i s new Temcometer instrument combines in a single, compact unit an advanced type of input con troller and an indicating pyrometer. Unlike other type controllers, t h e Temcometer automatically main tains even temperature regardless of fluctuations in line voltage. A sensitive panel-operated thermostatic switch can be set to regulate current input into the heating equipment anywhere from 5 % t o 100% time "on". Originally designed as a built-in feature of Temco electric furnaces, this complete control unit is now made for use with other makes of furnaces and elec tric heating devices. Made both with and without pyrometer for maxi m u m loads r a n g i n g from 2.3 to 5.7 kw. Priced from $30.00 to $57.50.
