## **Important Ordering Notes** ## **Base Metal Thermocouples** Prices given for 300 mm (12") lengths. Other sizes and lengths are available on special order. A 300 mm (12") length corresponds to a 600 mm (24") loop. To order longer lead lengths for base metal calibrations of 0.125 mm (0.005") or larger, additional cost per 300 mm (12") per package. Additional wire diameters are also available for Type N. Please check with Sales. ## **Base Metal Calibrations: 300 mm (12") Length Standard–Package of 5** **Wire Dia. Model Wire Dia.
