Sew RCB-3-1T(A)
|
|
FEATURES
● The RCB-3-1T is used to verify and proof any High Voltage Insulation Testers. It can be utilized to calibrate all High Voltage Insulation Testers very accurately Analogs or Digitals.● Some institutions and large industries requested their own calibrator too, therefore, SEW started manufacturing the RCB for special customers.
