DMO200 Digital Micro-Ohmmeter
200 A DC micro-ohmmeter for contact-resistance testing on breakers, isolators and busbar joints, resolving to 0.1 µΩ at 6.9 kg.
Measures contact and joint resistance down to 0.1 µΩ using test currents from 1 A to 200 A DC, with ripple held under 2.5% so readings stay stable on inductive joints.
Range selection is automatic and current, voltage and resistance are displayed together, so a technician reads the full picture on one screen rather than deriving resistance by hand. Readings persist on the display after the output is switched off.

Questions about this part
Where can I buy the T&R Test Equipment DMO200?
Not on our shelf today. Z Power Electric sources this part through independent, surplus, and new-old-stock channels rather than waiting on the factory queue, and confirms price and lead time within 24 hours. Z Power Electric is an independent MRO supplier in Calimesa, California — we buy outside authorized distribution, which is why we can quote parts that a standard distributor shows as unavailable.
Is the T&R Test Equipment DMO200 discontinued or obsolete?
Manufacturer lifecycle status changes by part number and region, so we confirm it per quote rather than publishing a claim that may be out of date. Either way it does not change what we do: we source discontinued, obsolete, and backordered parts as a matter of course, and the quote states whether we located the original or are proposing an equivalent.
How long does it take to get a quote on the T&R Test Equipment DMO200?
We respond to every sourcing request within 24 hours, and the quote states a confirmed ship date rather than an estimate. Mark the request urgent if the part is holding up a line.
Is Z Power Electric an authorized T&R Test Equipment distributor?
No — and that is the point. Z Power Electric is an independent supplier, so we are not limited to T&R Test Equipment's authorized channel or its order book. We source through surplus, new-old-stock, and independent inventory, and we state the condition and source channel of every unit on the quote.
