The Trerice TRS16 Selector Switch  
is the ideal accompaniment for the 
Trerice TRD16 Digital Indicator. The 
TRS16 allows economical measurement 
of multiple individual processes (using 
the same thermocouple type) while 
requiring only one digital indicator. 
The push buttons indicate which 
process measurement is currently 
displayed on the indicator. Size is 
96 mm x 48 mm (
1
/8 DIN).
