Non-] compensated conductors(copper/copper) will not introduce significant error in this range. For the larger temperature gradient of 0° C to 100° C across the extension portion of the circuit, the use of non-compensated (copper/copper) extension wires may result in small errors, which will not exceed the ASTM E230 tolerances given for measurements above 1000° C._ _******[Black on EXGG wire.]_ _**†** Weight of spool and wire, rounded to next highest kg (lb) (does not include packing material)._ _**Ordering Example: EXGG-B-20-25,** 25' spool of extension thermocouple wire, Type BC, 20 gage, stranded, glass insulation._ ## **Extension Grade W5%Re/W26%Re Duplex Type CX** Compensating Extension Wires for W5%Re/W26%Re Thermocouples **Color Code:** For EXGG Wire, Positive Wire, White/Red Trace; Negative Wire, Red; Overall, White/Red Trace For EXX **[††]** Wire, Positive Wire, White; Negative Wire, White/Red Trace; Overall, White/Red Trace |**Insulation No. Number**|**AWG Model**
