Kind Regards, Tester co uk ## Customer Reviews ### ⭐⭐⭐⭐⭐ Speakers sound better after using this *by on Reviewed in the United Kingdom 24 August 2021* Has made my movie listening far better after using this to dial in my 5.1.4 Atmos setup ### ⭐⭐⭐⭐ Bought to test audibility on Fire alarms and services plant. *by on Reviewed in the United Kingdom 2 December 2021* OK its chinese, it will never be a Rhode and Schwarz but for a quick test to see that the dBa of the alarms is in the right ball park, it does it quite well. Nicely built. Could do with a protective case with it and for the money, even a slip cover would be good. Fortunately I had the box my previous meter came in that was replaced with this one after it died. Overall a reasonable tool ### ⭐ Failed badly on frequency response tests, insensitive *by on Reviewed in the United Kingdom 27 November 2012* I tested this thoroughly in our microphone calibration room alongside our reference mic. Calibration at 1kHz 90dB SPL was spot on - it read 90.0! However, this is only part of the story. Tests at ten frequencies revealed that the A-weighting is nowhere near correct. Errors were: 50Hz +16dB, 100Hz +0.3dB, 200Hz +1.6, 2kHz +0.3 10kHz +13.5dB!! 12.5kHz +7.3dB.The gross errors at 50Hz and 10kHz are totally unacceptable and massively outside the standard specification. The peak at 10kHz will make it read very high on noise sources with high frequency content. Note also that the minimum reading is 40dBA which makes it useless for measuring noise on fridges, air conditioning etc which normally fall in the range 20 - 35dBA. A shame as the analog bar is a nice feature. ## Frequently Bought Together - Extech 407730 Digital Sound Level Meter 40-130dB - Extech LT300 Light Meter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nl/products/51926108-extech-instruments-407730-digital-sound-level-meter](https://www.desertcart.nl/products/51926108-extech-instruments-407730-digital-sound-level-meter) --- *Product available on Desertcart Netherlands* *Store origin: NL* *Last updated: 2026-06-07*
