Contact resistance meter / CRM / Micro OHM Meter are manufactured and exported by Ajit Electronic Corporation. The instrument works on Ohm’s law principle. This instrument is suitable to test / measure the low resistance measurement of the contacts in breakers, bus bar joints etc.
We AJIT ELECTRONICS CORPORATION are Manufacturers, Exporters & Leading Suppliers of Contact Resistance Meter Loacated in Dombivli, Thane, Mumbai, India.
The digital contact resistance meter is sophisticated, highly accurate and user friendly instrument. This instrument is suitable to test / measure the low resistance measurement of the contacts, joints etc. The instrument works on Ohm’s law principle. A highly stable regulated DC power source with short circuit and over load protection is housed in the instrument. The regulated DC current is passed through the object under test and the voltage drop across the same is measured. The calculations as per Ohm’s law is done electronically in the instrument and resistance value is displayed.
Introduction : These instruments are specially designed to measure the resistance of the object such as breaker contacts, bus bar joints etc. These instruments are widely used in the power and distribution breaker testing and panel board manufacturers for bus bar joint testing.
