Overview
The Autool TN201 Digital Sound Level Meter is a compact and precise device designed to measure environmental and industrial noise levels accurately. It uses an A-weighting filter to mimic the human ear’s response, covering a sound range from 30 to 130 dB with a fine resolution of 0.1 dB and an accuracy of ±1.5 dB. The meter offers both FAST (125 ms) and SLOW (1 second) time-weighting modes, allowing users to capture fluctuating or steady sounds effectively, while simultaneously logging the maximum and minimum noise levels during measurements. Its backlit LCD ensures clear visibility even in low-light conditions, and a sensitive capacitive microphone guarantees accurate readings. Additional features include a data hold function to freeze readings, an auto power-off timer after approximately 120 minutes to conserve battery life, and a durable IP40-rated ABS plastic housing suitable for field use. Powered by three AAA batteries, the TN201 is ideal for monitoring noise in engines, workplaces, homes, and construction sites, and it comes with a three-year warranty along with lifetime maintenance support.
