The Fluke 117 and Fluke 175 are both professional True RMS digital multimeters, but they are designed for slightly different users. The Fluke 117 is built around fast electrical troubleshooting, especially for electricians working in residential, commercial, and light industrial environments. The Fluke 175 is a more general-purpose industrial multimeter designed for accurate measurement, broader bench use, and professional maintenance work.
The Fluke 117 stands out because it includes electrician-friendly features such as VoltAlert non-contact voltage detection, AutoVolt automatic AC/DC voltage selection, and LoZ low-impedance mode. These features make it faster and more convenient when diagnosing circuits, outlets, panels, switches, and ghost-voltage issues.
The Fluke 175 is part of Fluke’s 170-series industrial multimeter family. It focuses on accuracy, durability, and general measurement confidence rather than specialty electrician shortcuts. It is a better fit for technicians who work across electronics, industrial maintenance, control systems, bench testing, and general troubleshooting.
The decision comes down to workflow. If you are an electrician, the Fluke 117 is usually the better tool. If you want a more general-purpose industrial meter with excellent accuracy and a traditional layout, the Fluke 175 is the better long-term choice.
Best for most electricians: The Fluke 117 is the better buy if you work mostly on building electrical systems. Choose the Fluke 175 if you need a more general-purpose meter for industrial, bench, or maintenance work.
Choose the Fluke 117 if you want the better electrician’s multimeter with non-contact voltage detection, LoZ mode, AutoVolt, and fast field troubleshooting features.
Choose the Fluke 175 if you want a more traditional general-purpose True RMS multimeter with strong accuracy, rugged construction, and better fit for industrial maintenance and bench work.
The Fluke 117 is the more convenient choice for everyday electrical troubleshooting. VoltAlert helps quickly identify energized circuits, LoZ helps reduce ghost-voltage confusion, and AutoVolt simplifies voltage checks when speed matters.
The Fluke 175 is the stronger choice if you want a rugged, accurate, professional meter for broader electrical and electronic troubleshooting. It is less specialized than the 117, but more appealing as a general industrial and maintenance meter.
Don’t overbuy: If your work is mostly checking outlets, panels, lighting circuits, HVAC controls, and building wiring, the Fluke 117 gives you the features that matter most. The Fluke 175 makes more sense when you need a broader industrial meter rather than an electrician-focused tool.
Bottom line: Buy the Fluke 117 for electrical field work. Buy the Fluke 175 for general-purpose industrial and maintenance measurements.

Fluke 117 Overview
The Fluke 117 is designed specifically for electricians who need to move quickly through real-world troubleshooting tasks. It is compact, rugged, and focused on the measurements electricians perform every day: voltage, continuity, resistance, capacitance, frequency, and current.
Its biggest advantage is convenience. VoltAlert gives you built-in non-contact voltage detection, which is useful for quickly checking whether a conductor, outlet, switch, or fixture may be energized before moving to a contact measurement. It does not replace safe test procedures, but it speeds up initial checks.
The LoZ mode is another major reason electricians choose the 117. Ghost voltage can appear on long cable runs or disconnected conductors because of capacitive coupling. A high-impedance meter can display voltage that is not actually capable of delivering meaningful current. LoZ loads the circuit enough to help distinguish real voltage from stray induced voltage.
AutoVolt is also useful in the field. Instead of manually selecting AC or DC voltage, the meter can automatically detect the type of voltage being measured. That saves time when moving between control circuits, panels, power supplies, and building wiring.
The Fluke 117 is the best choice for electricians who want a compact professional meter with VoltAlert, LoZ, AutoVolt, and True RMS measurement. It is built for fast troubleshooting in residential, commercial, and light industrial electrical work.
- ✓ Built-in VoltAlert non-contact voltage detection
- ✓ LoZ mode helps reduce ghost-voltage confusion
- ✓ AutoVolt simplifies AC/DC voltage checks
- ✓ True RMS measurements
- ✓ Excellent for outlets, panels, lighting, controls, and field service
Skip it if: you do mostly bench electronics, industrial maintenance, or general-purpose measurement work where electrician-specific features are less important than a traditional industrial meter layout.
Fluke 117 Pros

Fluke 175 Overview
The Fluke 175 is a general-purpose True RMS multimeter from Fluke’s 170-series family. It is designed for technicians who want a dependable industrial-grade meter for a wider range of work rather than a meter optimized specifically for electricians.
The 175 is a good fit for plant maintenance, equipment repair, controls troubleshooting, appliance repair, electronics work, and general electrical testing. It provides accurate voltage, current, resistance, capacitance, frequency, and continuity measurements in a rugged Fluke package.
Unlike the Fluke 117, the 175 does not include VoltAlert, AutoVolt, or a dedicated LoZ mode. That makes it less convenient for building electricians, but not necessarily less capable as a measurement instrument. In fact, users who prefer a traditional meter without extra electrician-specific functions may prefer the 175.
The 175 is the better choice when your work is varied and you want one meter for broad troubleshooting rather than a meter tailored to panels, outlets, and building wiring.
The Fluke 175 is the better choice if you want a rugged, accurate, professional True RMS multimeter for broad electrical, industrial, maintenance, and bench troubleshooting.
- ✓ True RMS measurements
- ✓ Strong general-purpose measurement capability
- ✓ Good fit for industrial maintenance and repair
- ✓ Rugged Fluke construction

Key Differences
The biggest difference between the Fluke 117 and Fluke 175 is specialization. The Fluke 117 is an electrician’s meter, while the Fluke 175 is a general-purpose industrial multimeter.
The Fluke 117 is designed to make field electrical troubleshooting faster. VoltAlert helps with quick voltage presence checks, LoZ helps clarify ghost voltage, and AutoVolt reduces switching between AC and DC voltage modes. These features matter when you are moving quickly through service calls, panels, outlets, lighting circuits, and HVAC controls.
The Fluke 175 is less specialized but more broadly applicable. It is better for users who want a traditional professional multimeter for mixed tasks, such as equipment repair, industrial maintenance, electronics troubleshooting, and general measurement work.
In simple terms: the Fluke 117 is better for electricians. The Fluke 175 is better as a general-purpose industrial and maintenance multimeter.
Real-World Performance Comparisons
Which Is Better for Electricians?
