Frigga M2H Reusable Temperature Humidity Data Logger Multi-Use USB Digital Temperature Recorder 28800 Points High Accuracy Refrigerator Thermometer Logger PDF CSV Report

Multiple report types. Great information. inexpensive. I have used this to track issues in several buildings. Couldn't have found the problems without this data logger.

Works great, high accuracy, and love that it also collects humidity data. If you're looking for a temperature logger this is a great choice. There are also a lot of customization options if you download the frigga software (change the units F/C and set the recording delay).

In theory these are a good idea. In practice however, they are pretty frustrating. Didn't realize that you could only use them with their PC/Mac software. Couldn;t hardly set them up without it. My main PC runs Win 11 and the software kept bugging out. Used an older laptop with Win 10 and it fared better. Tried my wife's Mac and found the software to be nearly unusable so went back to my Win 10 laptop. Finally got them all set up but they just feel like a beta product that still needs development..

We have an insulated shipping container that we heat with a small 750w heater. It's been very useful to see how below freezing temps effect the internal temps of the container throughout the day. Very happy with It's performance.

This is a quite simple temperature logger. Many of these originated during Covid to record the temperature of vaccine shipment and guarantee that the temperature was maintained throughout the shipment. That is the reason these have the stop disabled by default and barcode. Of course, there are many other uses for these but that is the original intention, so don't complain about that.This logger does what it says. The parameters can be set/changed from the software which is simple and intuitive. However, I had few times when the software didn't recognize the device and had to reconnect it. Other than that the device logged the temperature well at set interval. Temperature accuracy seemed fine. In my test it didn't fail once when used from -20°C to +50°C. Getting the report in CSV or PDF without the software is good option.Overall it work as intended, you should know its intended purpose and your use case.

The basic functions on this data logger work well, but in order to get all the bells and whistles, you need to download their software. Husband is not a fan of downloading random stuff, but even so, he did. If you want to set your time zone and temperature scale, among other things, you do need the software. The device seems to be well made, with a protective rubber cap.

The data logger itself seems to be nicely made and does a good job, but you really need the Frigga software app to change operating parameters of the logger. And the software is flawed.As it is, the logger starts logging after you hold the START button for five seconds and then after a 30 m delay. I prefer a shorter startup delay, but you need the software to control that. The STOP button is disabled by default so that the logger cannot be accidentally stopped. You stop it by plugging it into the USB port of your computer, and then the logger generates report files that can be accessed just like you would from a flash drive.I let the logger run overnight and then plugged it into my M1MacBook Pro. As soon as I did that, the logger stopped logging and generated a .pdf report and a .csv file that I could open in a spreadsheet. That was all fine.And as for the software, it’s a bit kludgy to be generous. I tried it on my Mac and I’ll say that, at least the application was available for the Mac and not just for Windoze, so I appreciate that. But after downloading software from the App store (and as of the available version 1.01 at the time of this writing) – the software pops a dialog box asking you to download and install an additional and undocumented piece of software.It more than requests, rather - it insists. The dialog automatically downloads this installer, even if you click on the CANCEL button! And that dialog box pops up again, each time you click cancel, you get another copy of this undocumented software.And since I don’t know what the software does, and it’s not been vetted by the Apple store, I did not run the installer (which I think might be some communications component). I ended up with a bunch of these installers that I had to throw in the trash.All that said – without installing that additional piece of software, the main Frigga application still did allow me to interact with the data logger and control settings such as the startup delay, Fahrenheit / Celsius, time zone, etc., so I don’t know why it is so insistent that I install that bit of undocumented software. It worked enough for me to set the parameters I wanted. But I don’t plan to use the software again.The hardware dongle itself seems to be rugged and I think it’s a nice logger. In my experience, many of these types of imported data products fail when it comes to software and this one is no exception.The little instruction booklet is not terribly useful, but there is a reasonable instruction manual available on-line, despite parts where there are poor translations. I give the company credit for that.I think that this product has the potential to be a pretty nice data logger if they can work out the kinks in the software and improve the usability a little bit.

The temperature and humidity loggers keep track of temperature and humidity automatically. I configured them with the Windows application Frigga Data Center. Once installed, I plug in each logger and configure them to certain temperature and humidity thresholds, the measurement interval, whether there should be a delay when I press the start button, whether I can restart logging, and whether to activate the stop logging button on the device. I always configure the loggers with restart logging allowed. I press the start button for five seconds to start logging. Once logging is done, I can plug the device into my computer again to read the created PDF or CSV file without having to open the Data Center application again. It saves me time because I don’t have to personally check the temperature and humidity constantly.
