However, it does not have a true RMS measurement, which can be important for some applications. The Quest DS-110 and TES-1352X are both more expensive than the Extech 430, but they do have true RMS measurement. The Quest DS-110 is also slightly more compact than the TES-1352X.
Ultimately, the best sound level meter for you will depend on your individual needs and budget. If you are looking for the most affordable option, the Extech 430 is a good choice. If you need a meter with true RMS measurement, the Quest DS-110 or TES-1352X are both good options.
Here are some additional factors to consider when choosing a sound level meter:
- The frequency range you need to measure.
- The maximum SPL you need to measure.
- The features you need, such as true RMS measurement, data hold, and max hold.
- Your budget.
