Klein MM600 vs MM700 – Choosing the Best Fit

Klein Tools, a symbol of American-made quality, has built its reputation on crafting reliable and durable tools that can take a beating. The MM600 and MM700 multimeters are no different. Their sturdy construction and dependable performance ensure they’ll be by your side for the long haul, withstanding the everyday wear and tear thrown their way. But which one reigns supreme?

Today, we clash a head-to-head showdown of Klein MM600 and MM700. Let’s get this meter matchup started!

Choosing the Right Multimeter

The best choice depends on your needs. If you primarily work on low-voltage projects or household circuits, the MM600’s functionality might suffice. But for professionals or those dealing with complex electronics, the MM700’s advanced features, like True RMS and LoZ mode, provide a significant advantage.

Difference Between Klein MM600 & MM700

After thoroughly testing both the Klein MM600 and MM700 multimeters, it’s evident that the MM700 emerges as the more feature-rich option. It boasts True RMS for precise AC measurements, a Low Impedance (LoZ) mode to prevent false readings, and an impressive temperature measurement capability that reaches up to 816°C—far surpassing the MM600’s maximum of 538°C.

While the MM600 is a cost-effective solution recommended for low-voltage tasks, the MM700’s versatility makes it suitable for a broader range of applications. Despite its higher price point, the MM700’s expanded features provide significant value, making it an excellent investment for both professionals and hobbyists seeking quality and functionality at a reasonable cost.

If I had to pick one, I would choose the Klein MM700 for its added features and affordable price, making it a superior choice for both professional and hobbyist uses​​.
