This is a simple sound level meter that complies with measurement laws, JIS, and IEC standards.
It can measure noise levels and output data to a level recorder. It is also capable of calculations such as equivalent noise level and time-weighted noise level. 【Features】 ■ Wide range of 100dB With a broad dynamic range, there is no need to switch ranges during measurement, allowing for safe long-duration measurements. ■ 24-hour battery life Continuous measurements can be easily conducted for long periods using dry batteries (when using alkaline batteries). ■ Built-in large-capacity memory For example, it can store instantaneous values every 100 milliseconds for up to 12 hours (432,000 data points). It can continuously store Leq and Lx every 10 minutes in the main memory for 50 days. ■ Built-in timer function Since the start and end times for automatic measurements can be set arbitrarily, simultaneous measurements at multiple points are now possible.
