Accuracy And Performance
How well do these brands perform when you need accurate measurements?
Kaiweets
Kaiweets multimeters are known for high accuracy, especially in their mid- and upper-range models. They often use true RMS (Root Mean Square) measurement, which gives better results for irregular AC signals. This is important if you measure the output of inverters, variable-speed drives, or non-standard waveforms.
Response times are fast, and readings are stable. The auto-ranging function helps avoid mistakes that can happen with manual settings.
Astroai
AstroAI models are accurate enough for most home and automotive tasks. Entry-level multimeters are not true RMS, so they may show wrong results with non-sinusoidal AC signals. Higher-end AstroAI models have true RMS, but at a slightly higher price point.
Manual-ranging models require you to set the range yourself. This can lead to mistakes and slower readings if you are not experienced.
