This is a brand new style 3.5 inch super large screen multimeter.Not only the screen is super large, but also triple line display can show both ACV and Hz on the screen, shocking your vision.It just 12mm thickness, when you hold it you can make a joke say this is a cell phone. Really interesting.


• Phone Size Design: Super-thin body and pocket size design make it looks ike a real phone. Ideal for daily diy use, teachal use, or fashion use.
• Large Screen 3 Line Display: Large screen triple line display can show 3 test results on the screen, such as voltage, frequency and analog bar.
• Automatic Identification Design: Automatic identification design allows for no-switching when testing AC/DC voltage, Hz, continuity and resistance.
• Unibody Design: Unibody design, no need to plug in and out probes, which not only can save learning and test time, but also prevent wrong insertion of ports, which may burn out the multimeter.
• Flashlight Design: Flashlight design makes measurement more efficient. Hang hole design makes it more portable.

    Hello, I just received my Mustool MT99, it came very well packaged and protected. It has its English manual and it really is a good multimeter, easy to use, it displays big clear numbers, and automatically adjust in accordance to what you are measuring, with the push of a button you can read capacitors, it has a light for obscure environments, It has a very lightweight
