Order Example:
 1. MIC-K-0.5-SS321, it means you order MI thermocouple cable is Simplex, type K, sheath dia: 0.5mm, sheath material: SS321.
 2. If you order MI thermocouple cable is Duplex, please change "MIC" to "MICD", it means "MICD-K-0.5-SS321".
 3. If you order MI thermocouple cable is Triple, please change "MIC" to "MICT", it means "MICT-K-0.5-SS321".
 4. If you order MI thermcouple cable is special limits, please change calibration "K" to "KK", it means "MIC-KK-0.5-SS321".
 5. For other calibration such as type N is also available.
