CONTACT RESISTANCE METER

CONTACT RESISTANCE METER

SCOPE :
“NTPL” make CRM, is capable to measure low resistances like contacts of Switch, Breaker, switchgear products, fuses etc. by circulating high value DC current, 100A to 20A, through contact/junction and measuring the voltage drop across the terminals and indicates the contact resistance in LCD display.
