Era lo necesitaba para medir temperatura de las neveras funciona muy bien lo recomiendo

buon prodotto ma non per uso non professionale .

erfasse damit schon über mehrere Jahre Temperaturen ohne Probleme, sehr lange Batterie Laufzeit

I am astonished by the negative reviews: it does exactly what it claims!I downloaded the app ElitechLog from the AppStore onto my iMac and it works perfectly.The app includes an excellent manual in perfect English. The .pdf file is brilliant because, once downloaded, it gives all the relevant data and an excellent graph which you can edit by filtering time, before printing or sharing.To use the logger, you just press the left hand button for 5 secs until you get REC and, after your period of monitoring press right hand button to STOP.Works fine on the USB port on my Mac keyboard: bit funny about ejecting, but no sleep lost over that.I suspect that you can download the .pdf and .csv files without the software, but the software is nice and gives averages etc.I think the negative reviews reveal more about the intellect of the reviewers than of the product!

Perfecto para la función que se le requiere , compré uno para probar y ahora tengo 3 instalados, buen producto
