11068. PYROMETERS, Brown High Resistance, Permanent Type, for wall use, with high resistance, 

 which renders its readings independent of the length or temperature of the connecting wires. 

 For use with either base metal or platinum thermo-couples. Resistance with base metal 

 thermo-couples, 600 to 1000 ohms.
