The Integrating Sound Level Meter is a combination meter and datalogger for monitoring SPL, Leq, SEL, MaxL and MinL in a 30dB to 130dB range. Its handheld design and LCD display allow for easy use and viewing of measuring sound levels. The LCD screen is able to switch between four display modes, has an analog bargraph to display the current relative range of input, and a built-in, real time calender and clock.
This logger can record up to 32,000 readings on Impulse/Fast/Slow settings, and has a programmable recording time to begin logging. This logger can either be used manually, or be setup with the included tripod stand to work autonomously.
