Elitech Digital Temperature Data Logger Medical Refrigerator Thermometer Vaccine Fridge Temperature Monitor, RC-4

Bad: Not that much bad stuff, actually. > Cannot set up or start/stop logging without a computer connected > Product data says the computer is just Windows (see below) > Not ideal as a temperature monitor, as the display times out after a few seconds Good: > Worked out of the box, after putting in the battery > Elitech download site has a Mac version! It's compatible with my MacOS 10.14.2 laptop. No bugs either - I made a few changes (turn off logging and enable button stop/start, change to F from C) and they showed up in the device after I hit Save on the laptop. Note: The download file description is deceptive: for USB interface, you do not need to load the driver (an odd thing on a Mac anyway). Just run the app, and it finds and talks with the device. It may require that driver for serial interface, but that's not what I needed anyway. I would definitely buy again. I'm a HW/SW engineer, always impressed by good performance and trouble-free software - especially at a very fair price. It worked immediately

Beware, the side contact for the battery was incorrectly bent on both the loggers I bought. Not knowing this, the first time I installed the battery, it squashed the side contact flat and the logger wouldn't work. I finally figured the problem out and bent the contact up so it touched the side of the battery. I see another reviewer has also encountered this problem, so it's a systemic issue. Just look carefully at the battery enclosure and make sure to bend the little "humped" contact so that it contacts the side, rather than the bottom face, of the battery. After that, both data loggers worked great. I'm using them to monitor run time on my home heating boilers, with the external probes attached to the sheet metal vent stacks. So far, so good. 5 stars, with one deduction for the bent battery contacts.

This small device is excellent at recording and charting the temperature, either stand alone or with probe attached. You can program alarms for out of range temps, set it to record at intervals needed, up to 16,000 samplings recorded! You can even set a delay before recording. Rechargeable internal battery. Convenient USB data/charge connection, and the application is very easy to use and understand. It's hard to believe this very accurate scientific device is so AFFORDABLE! I use it to verify the temperature of probiotic yogurt I incubate. Turns out my 'cooker' runs a degree or two high so I now know I need to set it lower accordingly. I am SO GLAD I thought to choose this one!

Poorly made product. Display shows nothing unless connected to computer. Software and documentation are poor. Battery compartment doesn't close properly. Internal and external sensors differ by about 4 degrees F. The external sensor is more accurate (internal reads higher), but the external one is off by 2 degrees or more when compared with reference thermometers. I'm returning this product.

We’ve been using this Elitech digital temperature data logger in our medication refrigerator, and it has worked so much better than the previous model we tried. It’s reliable, accurate, and incredibly convenient to have all the temperature readings digitally recorded without any extra effort. The setup was smooth, and we love having clear, consistent logs for compliance and peace of mind. If you need a dependable thermometer for medical or professional use, this one is definitely worth it!

Seems simple enough, got the software and set parameters, got it to work one time, but that's it. It's dead now. Contacted Elitech support by email, they won't answer phone support line. We'll see if they come up with anything. Update: Ok, support called me and fixed the problem. It was operator error. I did it. The device needs to be reset on the computer after every session. Do I see that in the instructions? I'm satisfied with it.

The device is inexpensive and does what you'd expect for the price. Everything seems to be accurate and the software, while simple, is useful. Customer service is phenomenal. I received this on a Friday afternoon and decided to download the software form the site instead of installing from the CD. After installing, the software would not recognize the device. I emailed support thinking I won't hear from them until next week, maybe not at all. I almost processed the return with Amazon. Before I got that far, support sent me a the correct software and even called me to make sure I received it. Resolved in less than an hour on a Friday afternoon. Best response ever.

excellent price for the given performance delivered. Internal temp sensor or plug-in external temp probe. Had to find PC USB driver on usb chip makers website, to make windows 10 OS talk to this device (did not work after installing data capture program). Software configuration and data download work great, very nice trend graph or data table display of temp data, or csv spreadsheet export. A very good value for this performance.

I originally thought the RC-4 data points could not be cleared thus the device would be filled up and became a throw away.. Not so, thanks to information received from Elitech Support. I received this via email from them: "When you export the data then click Save Parameter, the historical data will be clear and the memory will be released for continuous recording. " It works perfectly!

I downloaded the elitech software for my MacBook to work with the data logger as recommended by the manufacturer. However, the system does not permit me install it saying it is not approved by Apple.

This equipment is not working properly

I am using on a Mac, so these comments apply to that: The setup instructions are way out of date. File names in the instructions do not correspond to the download. The files I did download were flagged by my system as needing to be updated to be loaded. I did go to the CHAT which was very helpful. They walked me through it. I was a bit nervous to override the Apple warnings about the files needing updating for security reasons. But I did so as I wanted to get this working. When the program loaded it advised that there was an update, which I downloaded. I am unclear if this new update fixed the problem Apple was being cautious about? Operating wise it all seems to work fine. But the Manual is quite vague and you need to do some trial and error to really see how to set things up. I am still unclear about some things, but I am logging what I need to log and able to download to XL format, so that works for me

Looks good so far, downloaded the software to set up the parameters for the logging, and put it in the greenhouse to monitor higs and lows each day .So we will see how it goes
