Klein MM600 Multimeter Review
Klein MM600 Review:
Klein Tools proclaims its self-designed multimeter, the Klein Tools MM600 HVAC multimeter, is made “by electricians for electricians.” It’s a low-budget meter, equipped with innovative, time-saving features that can be used in light industrial locations, businesses, and at home.
This automatic ranging digital handheld multimeter measures up to 10A AC/DC current, 1000V AC/DC voltage, and 40M resistance. It is also capable of measuring temperatures, frequency, capacitance, continuity. Need to measure test diodes and duty cycle as well? The Klein MM600 can do it.
Klein Tools is a US company that is well-known for their meters and other quality tools. The company has been designing premium quality handheld tools for six decades. It has made the list of the Best Multimeters Under $100, but how does the Klein Tools MM600 HVAC Multimeter hold up?
Features and Benefits of the Klein MM600
Time to break it down and put each feature to the test.
Voltage & Current
The MM600 can measure up to 1000V AC/DC voltage. For current it can measure up to 10A AC/DC, which is perfect for an electronic hobbyist, such as myself, to use around the house and at my store. With that said, many meters have auto-sensing on the voltage setting. The MM600, on the other hand, automatically sets to AC and to switch over to DC you have to press the “SEL” button. It would be helpful if it had the option to set the default or to automatically detect between the two.
Along with its ability to read voltage, current, capacitance, frequency, continuity, diode testing, and continuity, it also reads the temperature. You can choose to display °F or °C by clicking the ‘SEL’ button to switch options.
Design & Durability
I was very impressed with the design of the Klein MM600. Everything is well built and doesn’t feel cheap at all. It is built with strong heavy plastic surrounded by a chunky rubber casing. I have dropped it a few times and it still works, and doesn’t show any damage. Durability? Check.
The dial movement is crisp and doesn’t feel loose. It comes with a big display screen that is easy to read. There’s also a bright backlight that makes it convenient to work in areas that aren’t well lit. It’s supplied with quality probes and attachable alligator clips, making it easy to switch between clamping or probing something.
It has a place on the back to hold the probes when they are not in use. The battery box compartment is easily accessible, making it convenient and simple to change the batteries and replace the fuses. There is also a low battery indicator which is a useful feature. A nylon bag is included, to store the meter and accessories away from dust.
The Klein multimeter MM600 has a CAT III 1000V / CAT IV 600V safety rating. It is equipped with high rupturing capacity fuses, allowing it to control a short circuit and heavy current for some time.
It is perfect to use in low voltage environments and designed for testing on the primary supply source. I find this to be true and have never had any problems using it around my house. Its CAT III rating allows me to use it on the lighting system in my store. However, it probably won’t suit someone looking to measure higher voltages.
What Users Say About The Klein Mulitimeter MM600
I find the Klein MM600 the perfect fit for me and it lives up to everything that it is supposed to. This should be the choice multimeter if you are in the market for a meter under $100.
However, what are other users saying about it?
Before purchasing, I did extensive research and after reading numerous reviews, this is what I gathered. Although there were a handful of negative comments from users, I would say 95 percent of feedback was positive and almost all users were satisfied with their purchase.
