- You don’t mind a lower build quality and just want something that works for occasional use.
ā Who Should Skip All of These?
If you need accurate digital readings, data logging, auto-ranging, or any kind of advanced electrical troubleshooting ā skip all three analog meters and grab a decent digital multimeter instead. Analog meters are great for learning and simple checks, but they’re not the right tool for professional diagnostics or precision work.
For the vast majority of home users and hobbyists, I’d grab the Gardner Bender GMT-312. It’s the most trusted, simplest to use, and backed by over 790 happy reviewers ā you can’t beat that peace of mind for basic electrical work.
Frequently Asked Questions
Which is better for a beginner ā the Gardner Bender GMT-312 or the Tekpower YX360-TRE-B?
I’d point a beginner straight to the Gardner Bender GMT-312. It’s simpler with only 5 functions and 12 ranges, plus the color-coded display and test lead input icons make it much harder to mess up. The Tekpower has way more features at 8 functions and 19 ranges, but that complexity can be overwhelming if you’re just learning to read a needle. The Gardner Bender also has 791 reviews at 4.5 stars compared to the Tekpower’s 187 reviews ā that’s a lot of beginners who found it easy to use.
Is the Smgda analog multimeter worth the lower price compared to the Gardner Bender?
Honestly, no ā I don’t think the savings are worth it. The Smgda has a 3.6-star rating from only 56 reviews, and it lacks features like continuity testing that the Gardner Bender includes. The Gardner Bender also has UL approval and fuse overload protection, which gives me way more confidence when I’m poking around a circuit. You’re getting a much safer, more reliable tool for the money.
Which analog multimeter measures higher voltage ā the Tekpower or the Smgda?
Both the Tekpower YX360-TRE-B and the Smgda measure up to 1000V AC and DC, so they tie on max voltage. The Gardner Bender GMT-312 only goes up to 300V, so if you’re working on higher voltage circuits, skip that one. Between the Tekpower and Smgda, I’d take the Tekpower every time ā it has 19 ranges and 8 functions versus the Smgda’s limited feature set, plus a much better 4.4-star rating.
Does the Gardner Bender GMT-312 have a diode check or transistor test?
No, the Gardner Bender GMT-312 doesn’t include diode check or transistor testing ā it’s a basic 5-function meter focused on voltage, current, resistance, continuity, and batteries. If you need to test diodes or transistors, you’ll want the Tekpower YX360-TRE-B, which has both features built in. That’s one of the main reasons the Tekpower costs a bit more and offers 8 functions instead of 5.
Which analog multimeter is the most portable and lightweight?
The Gardner Bender GMT-312 wins by a huge margin here at just 0.05 pounds ā it’s basically pocket-sized at 3.5 x 2.38 x 1.13 inches. The Smgda comes in at 3.15 ounces, which is still light, but the Tekpower weighs 0.44 pounds and measures 6.75 x 1 x 4.75 inches, making it the bulkiest of the three. If you’re carrying your meter around all day, get the Gardner Bender.
Can I measure DC current lower than 1mA with any of these analog meters?
Yes ā the Tekpower YX360-TRE-B can measure DC current as low as 10 microamps, which is 0.01mA and something most digital meters can’t do. The Gardner Bender goes down to 250mA, and the Smgda goes down to 0.5mA. So if you need to measure tiny currents like leakage or sensor outputs, the Tekpower is your only real choice here.
My Final Verdict
After comparing all three, the Gardner Bender GMT-312 is my clear winner for most people. It’s the most trusted with 791 reviews at 4.5 stars, UL approved, and pocket-sized at just 0.05 pounds ā perfect for home DIYers and beginners who want something simple and reliable. The Tekpower YX360-TRE-B is the runner-up for anyone who needs extra features like diode testing, transistor checks, or the ability to measure down to 10 microamps.
If you’re still on the fence, ask yourself this: do you need 19 ranges and a mirrored scale, or do you just want a proven meter that works every time you pull it out? For most of you, the Gardner Bender is the smarter, safer bet.
