MicroOhmmeters are used to measure the very low resistance of metals. This tool is useful in finding internal defects in metal welds, circuit breaker and relay contacts. The presence of contaminants like rust or carbon can cause a significant change in resistance.
When planning to invest in a microOhmmeter, consider getting one from Megger, as they offer several MicroOhmmeters to cater to your needs.
Here are some DLRO models offer for rent from Protec:
Megger MOM2 200 Amp Micro-Ohmmeter offers High Current Output Even on Batteries is about a handheld MicroOhmmeter which can put out a high test current of 220 Amperes. Most testers that offer high current output are bulky and needs to be powered by the AC mains. This tester is very convenient because it is powered by batteries.
Megger DLRO600 Digital Micro-Ohmmeter a versatile instrument that can provide test currents from 10 amps up to 600 amps subject to the load resistance and supply voltage.
Megger DLRO10HD Digital Low Resistance Ohmmeter (DLRO) combines simplicity of operation with a rugged IP65 case designed for stable ground and bench operation.
Megger DLRO200-115 Digital Low Resistance Ohmmeter measures contact resistance in high voltage circuit breakers, disconnecting switches (isolators), busbar joints, or for any other low resistance measurement.
If you want to evaluate the testing features of these testers, you can rent one from Protec. Our equipment inventory also has other tools to suit your needs. Contact our friendly specialists today to request for a quote.
