For 2-wire construction, change “-2” in model number to “-1”, for 4-wire construction, change to “-3” (color code is red/white, red/red/white or
red/red/white/white) for additional cost.
For special probe lengths, change sheath length in model number to required sheath length in inches for additional cost per inch.
For lead wires other than 6" long, add lead wire length in inches after the “-SL” in the model number for additional cost per foot.
For fiberglass insulated lead wires and 500°C capability, add “-GG” to the model number for additional cost.
