RC-5+ PDF USB Temperature Data Logger Reusable Recorder 32000 Points High Accuracy

Very good

Good one.

Fiquei chocado com a versatilidade! Comprei pra comprar pra garantia que uma geladeira não esfriava o suficiente e acabei arrumando desculpas pra usar na "caixa que esfria" alheia por pura curiosidade.

Buena calidad

I initially purchased two units, an RC5+ and an RC-5+TE. I have since purchased two additional "TE" units. These loggers are intended for use in monitoring shipments of food and other goods that need to be kept cold, so of course a record of the shipping conditions is essential. Check the specs to get an understanding of their outstanding flexibility. My use is in monitoring temperatures in rooms in which the air conditioning or heating may have problems, so I need to be able to monitor fairly rapid temperature changes. If you need to monitor for conditions like this, you should buy the "TE" version which adds an external sensor on the end of a cable about 3 feet long. Nothing magic about that sensor, there is another one like it inside the RC-5+ case and you can choose which to use, but the external one has much less mass than the case so it responds more quickly to temperature changes. It took me a little while on line to find the correct application software to download. For a Windows PC that is ElitechLogWin V6.4.0. There is an understandable user manual included in the app, but it has some omissions I found annoying. Most of those have to do with how to transfer data from the logger into the PC, how to configure the logger, and how to choose stored database files to display. This is like any other competent tool that's new for you, not everything is obvious and there is a learning curve. But the hardware and software work just fine, and the plotting routine (PDF only) is marvelously capable. Not only can you overlay multiple data logs, you can even display (and export!) logs that only partially overlap -- and the software takes care of this offsetting and scaling for you! And you can change the X-axis scaling and location of the viewing window; it's a little clunky in my opinion, but workable and I'm making fewer errors now. If I didn't feel these are marvelously capable and well worth their cost, I wouldn't have bought two more soon after the first two! The only reason it didn't get 5 stars from me is what I consider some obvious omissions in the user manual explanations. Martt Harding
