It reads from 30dB to 130dB with an accuracy of ±1.5dB, covering everything from quiet office spaces to loud industrial areas. The frequency range runs from 31.5Hz to 8.5kHz, and readings are shown in 0.1dB steps on a 4-digit LCD screen. It complies with the EN61326-1:2013 standard.\u003c\/p\u003e\n\u003cp\u003eInside is a 12.5mm diameter electret condenser microphone. You can switch between fast (125ms) and slow (1 second) response times, and choose A- or C-weighting depending on the type of noise you're assessing. A-weighting matches how the human ear responds to sound, while C-weighting captures more low-frequency content. Maximum and data hold functions let you capture peak readings or freeze a value on screen while you note it down.\u003c\/p\u003e\n\u003cp\u003eThis makes the TSL01 a practical tool for offices, industrial environments, airports and public buildings where you need to check or record noise levels. It runs on 4 x AA batteries, which are included, and weighs 308g with them fitted. The unit measures 256 x 70 x 35mm and arrives in a heavy duty plastic case with a windshield to reduce interference from moving air outdoors. It operates in temperatures from 0 to 40°C at 10-80% humidity.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBatteries\u003c\/td\u003e\n\u003ctd\u003e4 x AA (included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e±1.5dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency range\u003c\/td\u003e\n\u003ctd\u003e31.5Hz - 8.5kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e0.1dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 40°C, 10-80% humidity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage temperature\u003c\/td\u003e\n\u003ctd\u003e-10 to 60°C, 10-70% humidity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.31KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e256mm x 70mm x 35mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement range\u003c\/td\u003e\n\u003ctd\u003e30dB - 130dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/600106UK_2c6b171a-ca81-46c4-ac4b-dff85ecdb70e.pdf?v=1785038541\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat noise range can the TSL01 measure?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt measures from 30dB to 130dB, with a stated accuracy of ±1.5dB and a resolution of 0.1dB.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between A- and C-weighting?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA-weighting reflects how the human ear responds to sound and is common for general noise assessment.
