Elitech GSP-6 Digital Temperature Humidity Data Logger Pharmacy Refrigerator Thermometer Vaccine Fridge Temperature Monitor Max Min Value

Excellent piece of kit, software could be easier to edit, to cover separated periods of recording, but overall good value for money

I use this for measuring temperature and humidity in a portable incubator. When compared to a separate - and trusted - device it seems more than accurate enough for my needs, and within the stated accuracy of the device.The magnets in the back are useful and the screen is clear and easy to read. The screen is 'off' to save battery, unless the single switch on the front is briefly pressed. Don't press it for a prolonged period or the machine starts/stops.I think there are two hardware issues that detract. The first is that there's no way of turning the machine off altogether - for example, for long periods of storage - without removing the battery, or adding a piece of paper between the battery and the contact. However, even doing that is tricky as the battery compartment lid is difficult to remove and feels a bit fragile. I understand why there is no on/off switch, and there doesn't need to be if the battery was easy to remove. Secondly, the interface is micro-USB. USB-C would have been preferable, but this isn't a deal breaker.The software generates Excel and PDF format output together with a proprietary format that I can't open. The Excel format output timestamps are a single field (YYYY-MM-DD HH-MM-SS). The 'header' of the file - i.e. before the temperature and humidity data - contains all the machine and run parameters. I would have preferred the machine to also output an unformatted CSV file, though this can be generated with a little work from the Excel file. The Excel file can be read in Apple's Numbers.The PDF output - and the software that I used on a Macbook Air M2 - contains some labelling in Chinese. Sloppy. In an official report this would be unacceptable. The other oddity of the software is that it does not adhere to standard Apple UI details, like having a "Quit " option in the first menu item. You have to exit the program using the X in the top left hand corner of the window. Irritating.I've deducted one star for these 'features', but otherwise recommend this logger.Longevity has yet to be determined, either of the unit or the battery, but I'm pleased with it. I've used several other loggers and this is by far the best, notwithstanding the unfinished software.

Excellent device, well made and easy to use.

Once you figure out how to use the software and the device, it's pretty satisfying, especially for the price compared to other products on the market.

Firstly, and very weirdly, there appears to be no way of switching the thing off! You can alter the time the screen remains on, but there's literally no way to turn it off fully. Very odd.Works a treat for what I needed it for, I just wish it could record more frequent data points than every ten seconds.The software is decent and pretty user friendly.Don't regret my purchase overall.

Very good. Took some time to get the software. Was not ransferred from the unit to the PC. Had to go looking for it. But got it eventually. very pleased with the unit itself.

Not clearly described. It needs additional wired probe sensors.

Do the job, not too expensive and seems to be quite precise.If it lasts a long time it is a great product, we will see.
