Moisture meter recommendation

Good day everyone,

can anyone recommend a good moisture meter to reliably measure moisture in basement and underground garage walls?

It can also cost something...

Maybe some of you have experience with what is good - then I can be sure not to buy junk. :)

It is often said that those who buy (too) cheap, buy twice. ;)

Thanks & kind regards

Devices from the company TROTEC seem to be widespread. What I have been able to find out is that you should make sure that the measuring range does not end at 100 "digits," but goes up to at least 200.

The T660 (as the successor to the T650) and the T610 come into question. The latter is, however, disproportionately expensive.
