NL-53

Sound Level Meter For Noise Level Measurement

The NL-53 features a precision condenser microphone that is capable of measuring sound levels from 25 to 141 decibels (dB) with a frequency range of 10 Hz to 20 kHz.
The instrument is equipped with a large, easy-to-read TFT LCD touch panel display with backlighting that provides real-time readings of sound levels in decibels, as well as other key metrics such as frequency weighting, time weighting, and maximum hold.
A built-in data logger and various measurement value: A, C, Z weighting allows you to store up to 32,000 data points for post analysis.
A user-friendly interface that makes it easy to navigate and customize settings.
A compact and durable design that's easy to use in field calibration and to view its history.
Equipped with Type- C Connector
Compatible with USB Power Supply
Overall its accuracy, reliability, and ease of use make it a valuable investment for professionals.
The main unit’s input/output functions include an alternating current (AC) / direct current (DC) terminal, an RS-232C terminal, a USB terminal, and a LAN function for improving connections with communication devices.
It complies with the following laws and regulations related to sound level meters:
