👍 Pros & Cons of Each
Fluke 115
Pros:
- Reliable and accurate True-RMS performance.
- Compact and easy to carry.
- Slightly more affordable than the 117.
- Great for general-purpose electrical and electronic work.
Cons:
- No non-contact voltage detection.
- No LoZ function (ghost voltage readings possible).
- Lacks AutoVolt convenience.
Fluke 117
Pros:
- Includes VoltAlert non-contact voltage detection.
- LoZ function eliminates ghost voltages.
- AutoVolt saves time by auto-selecting AC/DC.
- Tailored to electricians and building service environments.
Cons:
- Slightly more expensive than the 115.
- Features may be unnecessary for hobbyists or light-duty users.
🏁 Which One Should You Choose?
- Choose the Fluke 115 if you’re a field technician, engineer, or hobbyist who needs a solid, general-purpose multimeter without extra electrician-focused features.
- Choose the Fluke 117 if you’re an electrician or building technician working in residential or commercial wiring. The added functions like VoltAlert, LoZ, and AutoVolt make troubleshooting faster, safer, and easier.
Both are excellent, compact multimeters built with Fluke’s trademark accuracy and durability — but the 115 is better for general use, while the 117 is optimized for electricians.
