Elitech USB Temperature Data Logger Reusable Digital Recorder Medical Refrigerator Thermometer Programmable Monitor RC-51 32000 Points High Accuracy (50 Packs)

We purchased 5 of the RC-51 data logger thermometers to validate shipping containers that are used to transport refrigerated products. We will be ordering more to monitor each shipment. The software used to configure the data loggers is fantastic... easy to install and use to configure the device parameters. The software is also used to read the data points from the data logger automatically when it is plugged into the computer usb port. As soon as the data is loaded a graph of the data is automatically produced along with a table of the time and temperature of each data point.The graph, table and device parameters are automatically used to produce a report which can be exported as a .pdf. Excel spreadsheet, a text file or another format I am not familiar with. The reports clearly document the temperature changes over the duration of the validation period (or shipment).The work effort to configure the data logger and place it into a shipping container, then read the data logger to produce graphs takes only a few minutes of work effort. Doing this procedure manual (with a fraction of the number of data points that were logged) required several hours of work effort. The labor savings with a single validation was greater than the cost of the data logger.The RC-51 data loggers have many useful features:Wide temperature range (-30 to +70'CNist certified- Data readings can be set from 1 reading every few seconds to 1 reading every few hours (with a 1 minute time interval the data logger has sufficient memory to last 22 days. With a 15 minute interval there str sufficient memory to read temperature fluctuation for over 1 year- Each data logger has a unique serial so the software automatically tracks the identity of the data logger- Historic data read from a data logger is stored automatically by the software- There are 3 settings for how the device can be set to start recording- Nist certified- Waterproof and dust proof

Performs well as advertised. One has to download software to start or take advantage of various features. It would be helpful if this could be done online.It is QA certified so if medicines need temperature monitoring, this satisfies that need. Long sampling period available and batter can be replaced as needed.

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.

Their claim that it can be used without a computer is completely false. It can only be programmed and reset by computer. It shows the highest and lowest temperature on its screen, but there is no way to reset it to start a new test without a computer. There is no way to view all the temperature readings it took during the period of time it was activated without a computer. Once a high temperature is reached, it will always display that high temperature until a higher temperature is reached, unless it is plugged into a computer and reset through the computer. Its instructions are practically nonexistent, and you definitely need instructions to figure it out. I finally found a video from Elitech on YouTube that helped a little, but it was very poor. They don’t even reference the video in the “instructions” that come with the device. It doesn’t say anywhere in the “instructions” or the video that you need to go to a website and download a program in order to program the device. After trying and trying to figure out what I was doing wrong and finally finding and watching their video a few times, it started to dawn on me I had to download a program to use it. I had been looking for the way to use it without a computer, but there isn’t one. Once I realized there must be a website somewhere to download the program, I searched in the “instructions” and found a website listed in small letters at the bottom. It didn’t say anything about needing to go to the website and download something, it just listed it. I wanted to use this device to monitor the temperature of the cooler where I keep my medications while traveling for days with no access to a computer or electricity, but it won’t work because as soon as I open the cooler and take out the device to check the temperature, it starts warming up and that higher temperature will always display as the high temperature until the device is reset by computer. Wish I could return it.

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

Why does the Software need to run full screen? It just feels like we will TELL you how to use it and we will DO anything we want. I really feel like this thing has to be sending info from my machine back to HQ without any control or say. Not happy with it requiring installed software that gives me nothing.

The device kept very good track of temp and with a fine gradient if time. However, the device is not terribly user friendly as well the software.

Bought this because my sister thought there was something wrong with her freezer. Easy to setup and use. Software is intuitive. Measurements are more than adequately precise.

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

Tiene gran capacidad de almacenamiento de datos

I received the product fast, it's good a quality product and I happy with my purchase and will order again.

Used it to log temps in the greenhouse over the winter. Computed the number of minutes per to last 8 months before reset. Had a small user error (mine) when programming it as I selected 10s vs 10m and the buffer filled up. Fixed it when I noticed after taking the first weeks samples and buffer was almost full.Has worked flawlessly up to -25C temps.
