Introducing our Digital Sound Level Meter, a versatile instrument designed to meet the measurement requirements of Safety Engineers, Health and Industrial Safety offices, as well as Sound Quality control in various environments. Whether you're in a factory, office, traffic area, family setting, or working with audio systems, this meter provides the accuracy and functionality you need. Here are the key features of our Digital Sound Level Meter:

Compliance with Standards:
The meter is designed according to the IEC651 TYPE2 and ANSI S1.4 TYPE2 standards, ensuring reliable and consistent measurements.

High Accuracy:
With an accuracy of up to +/- 1.5 dB under reference conditions, you can rely on precise and dependable sound level measurements.

Wide Measurement Range:
The meter has a measurement range of 30-130 dB, allowing you to capture a broad spectrum of sound levels, from quieter environments to louder industrial settings.

Weighted Sound Pressure Levels:
It provides two equivalent weighted sound pressure levels, A and C. These weightings enable you to evaluate sound levels according to different frequency response characteristics.

Dynamic Characteristic Modes:
Choose between Fast and Slow dynamic characteristic modes to suit your specific measurement requirements. Fast mode captures rapid changes in sound, while Slow mode provides a more averaged response.

AC and DC Outputs:
The meter offers AC and DC output options, allowing you to connect it to frequency analyzers, level recorders, FFT analyzers, graphic recorders, and other compatible devices for further analysis and data recording.
