Fluke 17B+ Digital Multimeter - Reliable Electrical Tester

Our review of the Fluke 17B+ finds it to be a rugged, straightforward digital multimeter aimed at electricians, HVAC technicians and serious DIYers who need dependable measurements on the job. The single biggest reason to buy is practical, field-ready accuracy combined with safety protections: the meter carries a CAT III 600V safety rating and measures up to 1000V AC/DC and 10A, making it suitable for most residential and commercial troubleshooting. It is easy to operate one-handed, offers temperature testing with the included thermocouple, and delivers the clear, long-lasting display that customers praise.

Key Features

• Safety rating: CAT III 600V protection helps reduce risk when working on common household and commercial circuits.
• Voltage and current range: Measures AC/DC voltage to 1000V and current to 10A so it covers a wide range of electrical tasks.
• Multifunction testing: Built-in resistance, continuity, capacitance and diode tests let you diagnose wiring and component faults quickly.
• Temperature capability: Includes a type K thermocouple for temperature checks to 400C, useful for HVAC and motor diagnostics.
• Easy operation: The simple control layout and clear display make one-handed use possible even with gloves on.

Who It's For

The Fluke 17B+ is best for tradespeople and experienced DIYers who need a durable, accurate meter for daily troubleshooting of electrical systems, HVAC equipment and small motors. Its safety rating and measurement ranges suit most residential and light commercial work where reliability matters.

Those who require specialized high-current (>10A) measurements, bench-grade lab precision beyond general field accuracy, or integrated logging and Bluetooth should look elsewhere; this model focuses on rugged, essential functionality rather than advanced connectivity or ultra-high current ranges.

Pros & Cons
