H3: Safety Ratings and Warranty

The Fluke 117 offers CAT III 600V protection and a 3-year warranty, making it ideal for general use. In contrast, the Fluke 177 steps up with CAT III 1000V and CAT IV 600V ratings, backed by a lifetime warranty. This higher safety standard is crucial for professionals working in high-voltage environments.

If safety and warranty are important factors in your decision, you might also want to explore how the Fluke 87V and 179 compare in our Fluke 87V vs Fluke 179 article. The 87V is known for its superior industrial features and thermal capabilities.

H3: Specialized Features and Functionality

The 117 includes non-contact voltage detection and low input impedance, features that make it especially useful for electricians identifying ghost voltages. However, if you need diode testing and a wider measurement range, the 177 is more suitable. This model supports AC/DC milliamps and includes advanced features like an analog bar graph and Min/Max/Average recording.

H3: True RMS Accuracy

Both the 117 and 177 offer True RMS for accurate readings even with irregular waveforms. This makes them excellent choices for diagnosing complex systems such as HVAC units or power supplies.

Those considering a slightly different model within the same family should read our Fluke 175 vs 177 comparison, which outlines the subtle but important differences between the two.

H3: Ease of Use and Build Quality

These models are built to last. The 117 is slightly heavier, but both are compact and ergonomic. Both multimeters come with durable holsters and are designed to withstand minor drops. The 177, however, features a clearer display with a built-in bar graph for easier real-time monitoring.

For those who prioritize ease of use, our Fluke 117 vs 115 comparison highlights how the 115 trades some features for simplicity and portability, making it a great budget-friendly option.

H3: Temperature Measurements

Neither model includes a built-in thermometer. If temperature measurement is essential to your work, you might be better off with a model that includes this feature or pairing these devices with an external probe.

Alternatively, our Fluke 87V vs 179 guide compares two models with built-in temperature features and advanced measurement capabilities.

H3: Performance and Reliability

Both models feature quick response times, a bright backlit display, and long battery life (up to 200 hours). Their performance is trusted in the field, and both are ideal for electricians, engineers, and technicians.

The Fluke 117 is part of a popular lineup, and our Fluke 17B vs 117 article is especially helpful if you’re considering budget-friendly alternatives in international markets. The 17B offers core measurement functions at a lower cost but with fewer safety and usability features.

H2: Final Verdict: Which Should You Buy?

Choose the Fluke 117 if:

• You need a reliable multimeter for general household or light professional use
• You prefer a lightweight, compact unit with non-contact voltage detection
• Budget is a key concern

Choose the Fluke 177 if:

• You need diode testing and higher safety ratings
