Decibel Meter, High Accuracy 30-130 dB Meter, Rechargeable Digital Sound Decibel Meter | A/C Frequency, Fast Sampling, 43,000 Data Record & Export, 3-Color Alarm Noise Sound Level Reader Data Logger

The GT1355A decibel meter data logger is a versatile, professional-grade sound level meter designed for accurate noise measurement, long-term logging, and easy data analysis. With storage for up to 43,000 records and USB connectivity, you can quickly transfer measurement files to a Windows PC (Windows 7/10/11) to print graphs or perform deeper analysis. Its 30–130 dB range, ±1.5 dB accuracy and 0.1 dB resolution make it suitable for environmental surveys, workplace noise assessments, machinery diagnostics, audio testing, concerts and HVAC inspections.Choose A-weighting for assessments that reflect human hearing sensitivity (environmental and occupational noise limits). Switch to C-weighting when measuring very loud or low‑frequency‑dominant sounds—engines, subwoofers, heavy machinery—or when you need less low‑frequency attenuation. Use FAST mode for rapidly changing sources and SLOW for steady background monitoring.The GT1355A’s IPS color screen shows trend lines, analog bars and real‑time/max/min values at a glance, while the 3-color LED alarm instantly notifies you when noise levels cross your custom thresholds. Built tough with an anti‑impact ABS shell and a metal microphone with wind muff, it also features a tripod mount for hands‑free logging.Recommended Applications:Environmental noise surveys and community noise monitoring;Workplace and occupational noise assessments;Industrial machinery diagnostics and preventive maintenance;HVAC, airport, traffic and construction noise checks;Audio system tuning, concert and venue sound monitoring;Schools, hospitals and residential area noise monitoring...SPECIFICATIONModel: GT1355ARange: 30-130dBAccuracy: ±1.5dBResolution: 0.1dBFrequency Weighting: dB(A) 30-130dB, dB(C) 35-130dBSampling Rate: 8 times/sec (FAST); 1 time/sec (SLOW)Powered by: built-in 1000mAh lithium batteryWorking Condition: 0-50℃, 10-80%RHDimensions: 2.2*1.2*6.3in / 56*31*160mmWeight: 4.02oz / 114gPACKAGE1 x Digital Decibel Meter1 x USB-C Charging Cable1 x Manual
