This is the kit I’d grab first for general home electrical work. The circuit breaker finder is a total time-saver, and it works as advertised to pinpoint the right breaker from a crowded panel. I really like the GFCI outlet tester with its backlit LCD; it gives you more detailed wiring fault info than a simple light-up model. The multimeter handles up to 600V and the NCVT detects from 12V, which is great for low-voltage lighting. It’s the perfect set for anyone who needs to map circuits or troubleshoot outlets regularly. The main limitation is that it’s a bit heavier than the 80067 at 1.78 pounds.
✅ Pros
- Circuit breaker finder solves a common, frustrating task
- Advanced GFCI tester with LCD for clear fault diagnosis
- High CAT IV 1000V safety rating for peace of mind
- Highly rated with over 1,500 reviews averaging 4.8 stars
❌ Cons
- Heaviest of the two kits at 1.78 pounds
- No thermal diagnostic capability
Klein Tools 80067 Electrical Test Kit with IR Digital Thermometer

- DIGITAL MULTIMETER measures up to 600V AC/DC voltage, 10A DC current and...
This kit is for the troubleshooter who thinks about heat. Swapping the breaker finder for an infrared thermometer lets you check for overheating breakers, connections, or motors up to 752°F. The multimeter is the same capable 600V model, and I found the non-contact voltage tester’s 50-1000V range perfectly fine for most household and light commercial work. It’s also the lighter kit at 1.29 pounds, which is nice for all-day carry. This is ideal for HVAC techs, appliance repair folks, or anyone who needs to add thermal scanning to their electrical checks. The trade-off is you’ll need another method to identify circuit breakers.
✅ Pros
- IR thermometer adds valuable thermal diagnostics
- Lighter and more compact at 1.29 pounds
- Competitively priced for a kit with a thermometer
- Non-contact voltage tester has a simpler 50-1000V range
❌ Cons
- No circuit breaker finder, a key tool for many
- Outlet tester is a basic model, not the advanced GFCI type
- Lower safety rating (UL listed vs. CAT IV 1000V)
Which One Should You Buy?
Both kits are excellent, but the right one for you comes down to your most frequent task. I find the choice is surprisingly clear once you match it to your job.
Klein Tools 80101 Circuit Breaker Finder Kit is right for you if…
- You’re a homeowner or landlord who needs to label a confusing electrical panel.
- You frequently troubleshoot outlets and want the detailed GFCI tester with the LCD readout.
- You value the higher CAT IV 1000V safety rating for working on service entrances or panels.
Klein Tools 80067 Electrical Test Kit with IR Thermometer is right for you if…
- You work on appliances, HVAC systems, or motors and need to check for overheating up to 752°F.
- You want a lighter kit (1.29 lbs) for your bag and don’t mind manually tracing breakers.
- Your electrical work is primarily standard indoor troubleshooting where a basic outlet tester suffices.
❌ Who Should Skip All of These?
If you’re a professional electrician who already owns a high-end multimeter and voltage tester, you might just buy the individual circuit finder or IR thermometer you’re missing. Also, if you only need a simple outlet checker, a single check current price on Amazon tester is all you need.
For most people tackling home electrical projects, my top pick is the Klein Tools 80101. The circuit breaker finder is a tool you’ll use constantly, and it solves a problem that’s otherwise a huge hassle.
Frequently Asked Questions
Which Klein Tools kit is better for a homeowner?
I recommend the Klein Tools 80101 for homeowners. The circuit breaker finder is an absolute big improvement for labeling your panel or finding the right breaker after a trip. Its advanced GFCI outlet tester with the LCD also gives you clearer information on wiring faults, which is more helpful for DIY troubleshooting than the basic tester in the 80067 kit.
Is the IR thermometer in the 80067 worth losing the circuit breaker finder?
Only if you specifically need thermal diagnostics. The IR thermometer is great for checking overheating breakers, motors, or HVAC components up to 752°F. If you don’t do that kind of work, the circuit breaker finder in the 80101 is far more useful for general electrical tasks. For most people, the finder is the more valuable tool.
Do both kits have the same multimeter?
Yes, both kits include a digital multimeter that measures up to 600V AC/DC voltage, 10A DC current, and 2MOhms resistance. This core tool is identical, so your decision should be based on the fourth piece: the circuit breaker finder versus the IR thermometer.
Which kit has a better safety rating?
The Klein Tools 80101 has a higher safety rating. It’s rated CAT IV 1000V, which is suitable for working on service entrances and panels. The 80067 kit is listed as UL compliant, but the spec sheet doesn’t mention the same CAT IV rating. For work closer to the power source, the 80101 offers more protection.
Can the 80101’s voltage tester detect low voltage like doorbell wiring?
Yes, it can. The NCVT3P non-contact voltage tester in the 80101 kit has a dual range that starts at 12 VAC, making it suitable for low-voltage applications like doorbells or thermostat wiring. The tester in the 80067 kit starts at 50 VAC, so it wouldn’t be reliable for those lower-voltage tasks.
Is one kit significantly lighter than the other?
The 80067 kit is lighter. It weighs 1.29 pounds compared to the 80101’s 1.78 pounds. The difference is noticeable if you carry your tools all day, but for most home use, the half-pound isn’t a deal-breaker compared to the added functionality of the circuit breaker finder.
My Final Verdict
After testing both, the Klein Tools 80101 is my clear winner. Its circuit breaker finder solves the most common and annoying electrical task, and it pairs that with a superior GFCI outlet tester and a higher CAT IV 1000V safety rating. The 80067 is a great specialized kit for someone who specifically needs the 752°F IR thermometer for thermal diagnostics.
If you’re stuck deciding, ask yourself this: will you more often need to find which breaker controls an outlet, or check if a motor is overheating? For 9 out of 10 people, it’s the breaker finder, and that makes the 80101 the smarter buy.
