Protmex Portable Digital Sound Level Meter, 30-130dB Decibelmeter with Backlit LCD Display with 4 Batteries for Indoor/Outdoor Use

Easy to use with full instructions, and very accurate.

Helped with my home cinema setup, set all the speakers to 75 decibels & improved the sound way better than expected. Slightly pricey so maybe some of the other cheaper meters will do the same thing but happy with my purchase.

Good device for a reasonable price. Managed to calibrate the studio setup and got a good result. Would be good if it had some way to mount on a stand or something.

Easy to use, very accurate and does what it says on the can Great Product

Product was easy to follow and operate

Very simple to use. Also very consistent in the measurements. A must have for a manual cal. of a home theater.

ery good item, just what i needed, thank you

Great product. Nice and solid.

Perfect voor de audio kalibratie van je Home Cinema installatie, en het meten van het geluidsniveau in verschillende ruimtes.

I wanted to monitor the sound at my gym and provide data to them on the levels. I found the device could not be seen in the dark of an RPM class and putting on the light was a total pain and disturbing. I didn't want to look at the device all the time and hoped to have a reasonable output I could use. You can buy a $2.99 app on an iPhone and get a better result. I compared the app to the device and found they gave a similar result. I was horrified to find that the device gets less reliable after a year and you need to spend a whole lot more to recalibrate it.

校正できないので正確性はわかりませんが、静かな住宅地で40db(A)前後の表示 でしたので、そんなにおかしな数値は出ていないように思います。 スマホの騒音計アプリはアプリによって全然数値が違うので、そもそも正確では なく、はかり比べても参考にはなりませんでした。 今度機会があったら校正されたものとはかり比べてみますが、個人使用には十分 な性能ではないでしょうか？ ボタンの文字等は何度も使っているとすぐに消えそうな感じでしたが、まー、押 してみればLCD画面の表示が変化するので分かると思います。 LCDにはMAXとMINの表示がありますが、MINのホールドはできませんMAXのみ。 電池は単4☓4本で、入れるところの精度が悪いのかキツキツですが、四角の9V 電池より入手しやすいので goodです。 マニュアルはなくても使えそうですが、必要なら「PT6708 manual .pdf」で 検索すると KPS-SN10という同等と思われる製品のスペイン語版の下に英語版 が記載された pdfが見つかります。 これを googl翻訳などにかければ日本語化できました。 マニュアルから 電源onで30-130dbの表示で大体のdbを把握し必要なレンジに▲▼で切り替えて 正確な測定をするように書いてあります。 使い方で注意するのはそれくらいですかね？

l'ho comprato per avere una certezza sul volume dei locali discoteche dove lavoro, mi ha risolto un gran problema con il gestore, che davanti alle continue lamentele del vicinato, ha vuto dei paramentri affidabili con cui dimostrare di essere in piena regola, l'apparecchio mi e stato consigliato dall'arpa lazio, che vengono a fare i controlli prima dell'inizio della stagione, ma poi si sa i dj tendono ad esaggierare si toccano alcuni paramentri ed ecco i dubbi, be con meno di 50 euro te li togli, abbiamo avuto sembre dati live per poter sapere di essere in regola con buona trenquillita dle gestore e anche del vicinato. ampio display retroilluminato ci vogliono due batterie per farlo funzionare, sul manuale c'e la procedura per settarlo e calibrallorlo al primo uso, poi ha diverse impostazioni fra cui anche una per i db di musica o alti rumori davvero completo

Para nuestra situación, muy bueno.
