Rion NL-43EX Class 2 Sound Level Meter

The NL-43 is a Class 2 sound level meter that has the same functionality as the NL-53 with an affordable price. The key difference between NL-53 and NL-43 is the frequency range. NL-43 covers 20 Hz to 8 kHz while NL-53 is capable from 10 Hz to 20 Hz, up to hearable limit of human sensitivity. In many cases, frequency up to 8 kHz covers the most frequency range that related to the annoyance to people, so choosing an NL-43 over NL-53 could be a good cost saver when your measurement task can be limited up to 8 kHz. Even because it is chosen by budget, NL-43 gives the exceptional performance promised by our quality standard. Fully complied with international standards IEC 61672-1:2013, ANSI/ASA S1.4.
