You will be paying VAT regardless, no matter if you buy it in Germany, EU, or non-EU. Don't try to weasel out of it, you'll just piss off your customs department (in fact, you'd be committing a crime)
VAT (regular or import) is paid on every good sold or imported to end users in the EU. It's inevitable, and just think of it as an additional income tax. If you want to avoid it, start a business that needs that equipment.
(Imagine the gigantic tax loophole if you could just import something from abroad and skip VAT. The only reason e.g. the US doesn't have apparent VAT on imports is that their taxation system works differently)
Customs rate on multimeters is 1.1%. Really not that big of a deal.
