Ohmmeters are an electronic device that measure electrical resistance, and come with different levels of sensitivity. Some are designed to measure low-resistance materials, while others measure higher resistance. The higher resistance the material has, the less current will pass through it.
An ohmmeter is typically not used to measure resistance across an entire circuit, but rather through various parts of the circuit, although it can be used to test that a circuit is not broken.READ MORE >>

Protec carries a full line of clamp-on meters, DC Current probes, transformer turn ratio meters, megohmmeters, micro ohmmeters, ground resistance test sets and other electrical test instruments.READ MORE >>
When verifying grounding resistance, a clamp-on tester makes it simple by simply clamping the sensor around the connection at the ground rod, and reading the resistance on the display of the instrument.READ MORE >>
Performing resistance measurement of a grounding system ensures that the grounding rod has good contact with the earth. The resistance of the grounding system to the earth may be affected by several factors like dry ground, partially uprooted stake, corroded connections and broken ground leads.READ MORE >>
The AEMC 6250 10A Micro-Ohmmeter is an accurate Micro-Ohmmeters with results up to 0.05% high accuracy, utilizing a four-lead Kelvin method of testing,
With the AEMC 6250 10A Micro-Ohmmeter resistance measurements are automatically calculated and displayed, taking into account the measurement value, ambient temperature, reference temperature and metal temperature coefficient. Sample temperature can be manually entered by the operator or directly measured by the AEMC 6250 10A Micro-Ohmmeter with an external RTD temperature probe.READ MORE >>
