E&OE Overview The FNIRSI FDM01 Decibel Meter has been designed to check noise compliance with safety regulations. It is used to perform acoustic analysis by safety engineers, health, industrial and safety officers as well as sound quality control in environments like factories, and offices, where traffic noise needs to be monitored and for any other noise monitoring applications. The FDM01 Sound Level Meter features Fast and Slow measurement switching. Fast measurement is more sensitive and picks up on fast-changing noise levels. Slow measurement is more stable and able to pick up on lower frequencies. Features Free sensitivity Temperature and humidity detection Light alarm Mobile app intelligent linkage Conforms to International Committee IEC651TYPE2 and American International Standard ANSIS1.4TYPE2 standards Measurement range: 30dB-130dB Accuracy: ±1.5dB A-weighting responses, with fast and slow response rate selection "Automatic shutdown in 15 minutes" function Dual mode switching with adjustable sensitivity Diligently designed with attention to detail Specifications Measuring Range: 30 ~ 130dB Dynamic Range: 3.50dB Accuracy: +-1.5dB Frequency range: 31.5Hz ~ 8.5kHz Sampling Frequency: 2 times/sec Resolution: 0.1dB Max/MIN/Average Mode Data Hold Temperature and Humidity measurements Backlight display Auto power-off in 15 minutes Microphone: 6mm high-sensitivity condenser microphone Digital Display: 2.3inch Colour LCD Compliance: CE, IEC651TYPE2, ANSIS1.4-TYPE2 standards Power source: built-in 600mAh/3.7V Lithium-Ion Battery USB-C Charging interface Dimensions: 190 x 61 x 31mm
