Good clamp meter for low DC currents

You really do have to consider ALL external sources of magnetic fields, but developing a technique and using the "zero" button has proven to give reasonably repeatable measurements. Measuring in the hundreds of uA isn't where it will shine, but - with a well practised technique - you might get some indicative measurements.

Wrap the/a wire n times around the clamp jaw, n times the sensitivity.

That applies to any clamp meter - and while it does improve low level measurements, it is not always convenient, especially when zeroing.

Once you have done this, do not change the orientation significantly. Otherwise you will immediately have a huge measuring error.

That doesn't look bad either.
