As an electrical engineer from Stanford University with over 7 years of experience using multimeters.

One thing that adds to the allure of Klein Tools is its solid US make. They have built a reputation for producing reliable and durable tools; the MM600 and MM700 are no exception. With their sturdy construction and dependable performance, you can trust these multimeters to withstand the rigors of everyday use.

This article reveals the thrilling tale of the Klein MM600 vs MM700. These two titans of the measurement realm are set to go head-to-head.

Let’s get this showdown started!

Klein MM600 vs MM700 – Which One to Consider?

Having had the chance to work with both the Klein MM600 and MM700, I must say the Klein MM700 stands out due to its additional features, including True RMS for more accurate AC readings, a Low Impedance (LoZ) mode, and an extended temperature measurement range up to 816°C, compared to the MM600’s limit of 538°C​​.

Even though the MM600 is suggested for low-voltage work and the MM700 for more varied uses, the MM600 is less expensive and offers more features, making it a better value for money.

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​​.
