Frequently Asked Questions

Which analog multimeter is better for a first-year electronics student?

I’d go with the Tekpower YX360-TRE-B if your student is serious about learning. It packs 8 functions and 19 ranges compared to the Gardner Bender’s 5 and 12, so it covers diode testing, transistor leak current, and higher voltages up to 1000V. The Gardner Bender is simpler and lighter at 0.05 lbs, but you’ll hit its limits fast once you move past basic voltage and continuity checks.

Is the Tekpower worth the extra money over the Gardner Bender?

Honestly, the price difference between these two is tiny — they’re both in the same budget range. For that small gap, you get almost double the features: 8 functions instead of 5, 19 ranges instead of 12, and the ability to measure up to 1000V instead of 300V. I think the Tekpower is absolutely worth the small bump in cost for anyone who wants room to grow.

Which meter is more accurate for reading resistance?

The Tekpower wins here because it measures resistance up to 20 MΩ with a mirrored scale and 20kΩ/V DC sensitivity, which reduces reading errors. The Gardner Bender only goes up to 1 MΩ and lacks the mirrored scale. For student labs where you’re measuring resistors in the kilo-ohm range, both work fine, but the Tekpower gives you more precision and range.

Can these meters test diodes and transistors?

Only the Tekpower YX360-TRE-B can do that. It includes a diode check that works with standard diodes and even LEDs, plus a transistor leak current test. The Gardner Bender GMT-312 has no diode or transistor function at all — it’s limited to voltage, current, resistance, continuity, and batteries. If you’re learning about semiconductors, the Tekpower is the only choice here.

Which one is more portable for carrying to class?

The Gardner Bender GMT-312 is way more portable at just 0.05 pounds with dimensions of 3.5 x 2.38 x 1.13 inches — it really does fit in a pocket. The Tekpower weighs 0.44 pounds and measures 6.75 x 1 x 4.75 inches, so it’s more of a bench tool than something you’d carry daily. If portability is your top priority, the Gardner Bender wins easily.

Do both meters have fuse protection for beginners?

Yes, both meters include fuse overload protection, which is critical for students who might accidentally connect to the wrong range. The Gardner Bender has “fuse overload protection circuitry incorporated,” and the Tekpower says it’s “all range fused.” I wouldn’t let a beginner use either one without that safety feature, and both have it covered.
