RC-51 Temperature Data Logger

Works the way it should. Shipping was fast. I'd recommend this to anyone looking for a data logger.

El producto está muy bien contruído. Buen material

de 9 am a 1pm eleva hasta 13 °C mas la temperatura que otros, no sirve, imposible regresarlo sale muy caro

After a problem with our refrigerator, I looked for a better solution for ongoing temperature monitoring than the classic $5 uncalibrated dial thermometer. I found this device, and based on the specs and reviews, gave it a try. I deliberately purchased the IP67 rated model rather than the version that included a humidity sensor. First, I am not particularly concerned about the humidity in the fridge. Second, the fully sealed pen could have its calibration verified by submerging it in an ice bath. The ice bath verified that it read 32°F dead on, until the glass of ice melted, then it followed the water as it warmed. Since then it has sat on a shelf in the fridge, knocking around among the jars of pickles, jams, and spreads. Occasionally, I've pulled it out to read it. And that process is a point where it shines. Once it is configured, you can simply unscrew the water-tight cap to reveal a USB A plug and plug it in to any PC. When connected, it will process its log and create a report in a PDF file, then act like a common USB pen drive so you can copy the report aside. No software is required to create the report, and the file it produces is readable with any PDF viewer. It is even reasonably nicely formatted, with a summary page at the front full of statistics and a plot, and a table of every temperature reading stored on the following pages. At this point (assuming you've read this far) you might be wondering what happened to the fifth star. I'd actually prefer to give it four and a half, but the rating system doesn't allow partial credit. My issue here is the software provided for download. You need to install and run this software in order to configure the logger. It does run, but it has a number of rough spots and outright blunders that make me wince. A big issue is that it did not follow any of the usual Windows conventions for installation location: and it defaulted to wanting to be installed in a folder on C:\. That is simply not done these days. Even after I forced the installation to a better location, it made a shortcut to the default folder instead of the place I moved it to. Installation foibles aside, the application is fairly clunky and not really all that friendly to a new user. It does look like it was intended to be used in a commercial setting to track and log a fleet of these loggers, and I suspect that a fleet of 100s would be just as inconvenient to deal with as my single unit. In a commercial setting, these are inexpensive enough that one could be included in the packaging of a temperature sensitive product when shipping, and you could expect the recipient to be able to produce and email the PDF report on receipt. For a high-valued shipment, the $25 logger might not even be worth the postage required to recover it. My bottom line is that I'm pleased with it living in my fridge, and I've already recommended it to several friends. I'm just not entirely enthralled by the software quality.
