DMO600 Digital Micro-Ohmmeter
600 A DC micro-ohmmeter for high-current contact-resistance testing where 200 A is not enough to seat the measurement.
Extends the DMO family to 600 A DC for large breaker contacts, generator connections and heavy busbar joints where higher test current gives a more representative resistance figure.
Automatic range selection with simultaneous current, voltage and resistance display, and results storage to USB for commissioning records.

Questions about this part
Where can I buy the T&R Test Equipment DMO600?
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 DMO600 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status changes by part number and region, so we confirm it per quote rather than publishing a claim that may be out of date.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 DMO600?
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.
