Extech Oscilloscopes MS420 Editorial Review

** Extech MS420 Digital 20MHz 2-Channel Oscilloscope** The Extech MS420 Digital Oscilloscope has received a rather lukewarm reception from users, with many expressing disappointment in its performance compared to more reputable brands. A common criticism is that the readings can be inConsistent when compared to the Fluke brand, which is typically held in higher regard for accuracy. Some users have specifically targeted its applicability to automotive diagnostics, indicating that it struggles with capturing starter profiles and even basic electrical checks, such as those required for a 110V outlet. Further compounding these issues, some customers have pointed out that the MS420 is essentially a rebranded version of the Owon HDS1022M-N, which is available at significantly lower prices. This points to a perception that buyers may be paying a premium for a product that doesn’t offer much in terms of functionality or reliability. Overall, the Consensus seems to be that while the oscilloscope is functional for basic tasks, it falls short for users who require precision and reliability in their measurements, earning it the label of a "poor product" or "toy" by some reviewers. **
