Title: How about these bias testers?

Thinking about getting this set.  Anyone use these types of adapters to measure bias.  I have a good fluke meter, and could just buy one adapter, but this dual set up might be "nice".

Opinions? Experiences?  Thanks!

Isn't that two $2.99 DMMs (which are adequate) with socket adapters like are sold on this forum's host's store?

Ah. Look below, click Tools and Batteries, he sells all the parts for an octal bias checker for external meter. I guess if you add two $2.99 DMMs, it's the same prices as the eBay setup.

Thanks for pointing that out.  I did look a little for them in Mr. Hoffman's store, but not in the right spot apparently!

I just happened to run across the ebay ones in a search for a weird tube.

This is not a bias tester , only a multimeter . Good Fluke is better than those one .

Yes it. It's a complete bias checker system complete with two adapters and two cheap meters.
