Ohmmeter that is accurate below 10 ohms?

It seems that most DVMs that I have used don't have much resistance accuracy below the 10 ohm mark. Is there anything that is accurate at that level? From 1 or 2 ohms to 10 ohms.

I would be ok with a straight ohmmeter with no other functions
 
Even a cheap LCR meter can do it.

2 cheap multimeter and a voltage source with a resistor in series can do the job.

One multimeter measures the current and the other measures the voltage in the Kelvin 4-wire connection.

You can measure even ultra low resistance (few miliohms) such as engine starters, alternators etc.
It's a matter of adjusting the proper current to produce easy readable voltage/current.
 
The HP 4328 milliOhmeter is about as good as it gets. For very low Ohms there are a lot of errors like thermal junctions that cause problems even with Kelvin connections. The HP uses AC and synchronous detection to measure the resistive component down to 1 milliOhm full scale. There is a later digital version for $$$$. This one is $179 https://www.ebay.com/itm/2866287997...P7HRRqYAXIRWH4baaN44bu7w==|tkp:Bk9SR8KNuM7sZQ You can get probes on eBay.
There are also meters for checking battery impedance which can work and maybe an ESR checker could work but my experience with the cheap Asian knock offs have not been good.
This may be a good option https://www.ebay.com/itm/4051422960...HeY4O9x/bGR5XPbSIrnq4tXoo=|tkp:Bk9SR-ab787sZQ The price is right and it seems to have accuracy. The controls are all in Chinese but I'm sure Google can help. . .

When measuring low resistance like that, the unwanted series resistance added by the probe leads and their connectors, as well as contact resistance between the probes and what they touch, will add quite a bit of error to the readings. It's best to find a meter that has kelvin or 4-wire ohms measurement capability when reading low-ohms resistors like the 10 ohm one. One pair of wires sources a constant current though the Device Under Test (DUT), and the current stays constant regardless of probe & contact resistance, so long as that resistance is not so high that the current source can no longer keep the current constant (goes into compliance). The other two probes go to the meter's voltmeter, a very high resistance input, and as a result, there's no voltage drop in the probes and their contact points due to the microscopic currents involved. So one pair of wires sources the current and the other pair reads the voltage, and the result is an accurate measurement of the low resistance. For high resistances this is not needed because the errors, usually under an ohm, won't make much of a difference when reading, say, a 100K resistor.
