Extech 430 Compare with Similar Item

a table comparing the Extech 430 to two similar sound level meters:

Feature	Extech 430	Hanwell SL-400	Quest DS-110
Sound pressure level range	30-130 dB	20-130 dB	30-130 dB
Frequency response	31.5 Hz-8 kHz	31.5 Hz-8 kHz	31.5 Hz-8 kHz
Accuracy	±1.5 dB	±1.5 dB	±1.5 dB
Weight	1.2 lb	1.6 lb	1.4 lb
Dimensions	5.5 x 2.5 x 1.5 in	6.3 x 2.8 x 2.2 in	6 x 2.8 x 2.1 in
Price	$60	$70	$80

As you can see, the Extech 430 is the most affordable of the three sound level meters, but it also has the narrowest frequency response range. The Hanwell SL-400 and the Quest DS-110 both have a wider frequency response range, but they are also more expensive.

Ultimately, the best sound level meter for you will depend on your specific needs. If you need a basic sound level meter for occasional use, the Extech 430 is a good option. If you need a more versatile sound level meter with a wider frequency response range, the Hanwell SL-400 or the Quest DS-110 may be a better choice.

Here is a brief summary of the key differences between the three sound level meters:

Extech 430: Most affordable, narrowest frequency response range.
Hanwell SL-400: Wider frequency response range, slightly more expensive.
Quest DS-110: Same frequency response range as the Hanwell SL-400, slightly more expensive.
