SDG #042 Mustool MT826 6000 Count Multimeter Review

The Mustool MT826 sits in the crowded budget bracket of Chinese-made handheld multimeters that promise a 6000 count display and true-RMS style specs for very little money. This review looks past the spec sheet to the things that actually matter day to day: how the display reads under bench lighting, how quickly the meter settles on a value, whether the ranging behaves sensibly, and how the rotary switch and probe sockets feel after repeated use.

Accuracy is the core question with any cheap DMM, so basic DC voltage, resistance and continuity behaviour are compared against known references to see whether the claimed tolerances hold up in the middle of each range and near the ends where cheap meters tend to drift. Capacitance and frequency functions are also worth scrutiny on meters at this price, since they are frequently the weakest implementations and can be slow or simply inaccurate on low value parts.

Just as important is the safety story. A meter that will be used on mains or automotive circuits needs adequate input protection, properly rated fusing and lead sets that do not compromise the category rating printed on the case. Budget meters often claim a CAT rating that the internals do not support, and the teardown side of this review shows what is really behind the front panel.

For buyers, the takeaway is about matching the tool to the task. A meter like the MT826 can be perfectly sensible as a second or third meter for hobby-level low voltage work, while anyone probing live mains regularly should weigh the compromises carefully before trusting a bargain-priced instrument.
