ElitechDigital Temperature Humidity Data Logger Medical Refrigerator Thermometer Vaccine Fridge Temperature Monitor Max Min Value GSP-6G

We have been having problems with excess water build up and overflow in the drip pan of our Sub-Zero refrigerator. The heater that is supposed to evaporate the water doesn't seem to be working properly despite multiple repairs. But how do I prove it isn't working correctly?Enter the Elitech Data Logger GSP-6. I set it to record temperature at 1 minute intervals. I now have a clear graph of a week's worth of data showing how the temperature of the water in the drip pan cycles between 72 and 82 degrees every few hours, which is not enough to evaporate the water. A senior service tech is now scheduled, based on this data. Finger crossed.This device is a quarter the price of other brands of data loggers that I looked at. The software is perfectly serviceable (I'm on a Mac). I was a little unsure how to set some things up, but trial and error and poking around on the desktop app were enough, along with other users' comments in reviews. There are a lot of features in the "Parameters" tab so you can really customize how this thing works. It is super easy to unplug the unit from the sensor cable and plug it in to my Mac via USB to download the data. The re-connect the unit to the sensor cable to continue collecting more data.Some people complain that the English translation of the manual isn't that great. It's not, but you know what - who cares? At least Elitech does provide written documentation, unlike many companies today who give you a scrap of paper with a few pictograms to scratch your head to. I struggled with some of the wording, like "to start press the button until the light flashes out." What is flashes out? But once I figured out what they meant by "flashes out" I started used that expression myself.Altogether, this is a very reasonably priced product that is a must-have if you need to monitor temperature and want to download a graph and data of the results. Be prepared to put on your thinking cap to figure out the software, but it is worth a bit of effort. I haven't used the humidity sensor yet but it could be handy some day. For now I'm keeping the humidity sensor in the surprisingly nice box that the data logger is packaged in. The box is a high quality you don't see much of today and even has a nice magnetic closing flap.

This is really a great tool for the price. I used it to log the temps. for a new "smart pump" that I installed for a client. Set it to log every minute and was able to discover an issue with cold water moving backwards thru the pump. Then I moved the sensor and discovered that the tank outlet temp. was set too high through the tempering valve and got these fixed before they became an issue. One reviewer said that the temperature on theirs was way off, mine was within 0.7 degrees (compared to a certified calibrated thermometer), the software allows you to add or subtract to adjust the calibration so that is a non issue. Other loggers that I looked at were either way more expensive or didn't have the features. This is a great tool for HVAC or plumbing trades to see how your setup is working without having to sit there and watch the unit all day.The parameter screen lets you set up everything exactly how you want it, turn it on and off in the field and download to a graph for simple view of what's going on, save as a JPEG for future reference. Temp. or humidity can be used separately or together. You do need to download it to a computer to view the data though.

I use this for storing and packing out refrigerated COVID and other vaccines for my mobile clinic. It passes state standards and functions well but you HAVE to leave it running. Comparing this to 2 other loggers, one state supplied and the other installed on the fridge, it's pretty accurate. Had a hiccup after about a month where the temperature suddenly stopped working. I worked with the manufacturer and they replaced the whole unit. Turned out it was the cord for the glycol bottle. I was able to replace the battery with a regular AA battery when troubleshooting the issue before replacement and it was fine. However the battery has never died and I leave it running all the time. The software is a bit clunky but I really didn't expect it to be sleek and easy for the money. 🤷🏾‍♀️ You get what you pay for.

Updated review: Nothing but trouble. Disclaimer, I am having to mail this logger back and forth to the place of instrumentation and coordinate with someone else to set it up. However, the logger has not functioned all three times I have mailed it back and forth. Wasting time and money. The first time, it didn't trigger properly. The second time, it triggered, and then I we tried to stop it so we could re-start it the next day. Apparently that is not possible without plugging the thing into the software again (that is NOWHERE in the documentation), so had to send it back again to reset. The final time, everything seemed to trigger properly, the logger started counting up, but at the end of the logging period it just wiped all of the data and will no longer connect to a computer. Garbage. They need better software engineering on this thing.Original review: What a great little tool! I am only using it for temperature measurement of graywater, so I can't comment on the humidity function. Super easy to set up and configure in the free software. Really nice software that has some nice post-processing automatically done. The auto graphing function is really nice. Great little device! Only wish it had a bit more internal memory, as I want to log every 10 seconds and it maxes out at 1D 20Hr of time. That's a minor niggle though. Highly recommend.

Very good value for money. The application is very easy to use. It comes with calibration and calibration certificate.
