RION Japan 

Class 2 Sound Level Meter

Model: NL-43

It complies with various standards, including IEC 61672-1 : 2013 class 2, JIS C 1516 : 2020 class 2 and JIS C 1509-1 : 2017 class 2. It can be used to measure noise emitted from factories, machinery and personal surroundings. The optional NX-43WR (sold separately) can be used to record sound, which can be played back on a PC, and the dedicated PC software AS-60 can be used to play back the sound and, if deemed unnecessary, exclude the sound from the calculation and recalculate it. The main unit is equipped with a colour LCD touch panel with language selection feature, making it easy to operate for the first time. The main unit also features a waterproof mechanism to reduce malfunctions caused by sudden rainfall or unexpected exposure to water. Measurement data can be stored on an SD card (up to 1000 hours) and stored data can be processed and edited using dedicated PC software AS-60 or commercially available spreadsheet software. The NL-43 has a new LAN communication function that enables control of the NL-43 and acquisition of measurement data from the web browser of a PC or smartphone, making it possible to manage measurements from a distance from the NL-43. “Connectivity” is the key word for RION’s new generation Sound Level Meters. More intuitive operation with a touch panel, LAN terminal for more expansion, USB Type C connector for power/data transfer and newly added measurement functions increase your noise measurement capabilities. We have carefully designed our new sound level meter to maintain the advantages of the previous model such as ease of operation, reliability and durability. At the same time, there are many new features in the new model to support your measurement tasks. Fully compliant with international standards IEC 61672-1:2013, ANSI/ASA S1.4. The NL-43, NL-53, NL-63 sound level meters are very popular noise meters in many different types of industries and applications because they can support measurements according to international and local regulations and guidelines. https://www.youtube.com/watch?v=TP27PMjpqGU Video: Sound Level Meters: NL-43/NL-53/NL-63 Promotional
