Our verdict

A Fluke is the meter people stop replacing. For pure kit building it is more than you need, but if you also work on household wiring, cars or anything where a wrong reading matters, the safety engineering and accuracy are worth paying for. Buy it when the meter has become a tool you rely on rather than an occasional helper.

Getting started with the Fluke 17B+ Digital Multimeter

Read the safety section of the manual once — a professional meter is only as safe as the way it is used, and the voltage ratings assume the correct sockets and leads. Keep the supplied leads rather than swapping in cheap ones, since the leads are part of the safety rating. For electronics, the capacitance and frequency modes are the features you will reach for most.

Who it's for

Serious hobbyists and anyone doing regular electrical work who wants a buy-once meter.

Fluke 17B+ Digital Multimeter: common questions

Is a Fluke multimeter worth it for a hobbyist?
Only if the meter will also be used for electrical work or you want one that lasts for decades. For kit building and small projects, a good budget auto-ranging meter covers the same everyday measurements.
Does the Fluke 17B+ measure capacitance?
Yes, along with frequency and temperature. Those modes make it useful for diagnosing electronics as well as electrical circuits.
Why are professional meters so much more expensive?
Largely for safety engineering — input protection, rated leads and fusing designed for high-energy electrical circuits — plus accuracy and durability. For low-voltage hobby electronics those margins are rarely tested.
