Elitech GSP-6G Digital Data Logger Detachable Buffered Probe Temperature and Humidity

NO LO PUDE INSTALAR

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.

Buyer beware. These seem to be decent data loggers but the description specifically notes they come with a certificate of calibration and were designed for vaccine storage. The certificates are 2 years expired, and if you plan on using these in a regulated space you will need to recalibrate/recertify. Plan on about $100 additional cost per unit. If you just need a data logger and the certificate is not important, you are good to go.

This appears to be a good thermometer. It sticks to the side of the fridge. The cords are long so you can place the temperature probes in most places in the fridge with ease. However, the directions and the website were difficult to follow. The website listed in the directions was in correct. I called my computer tech at my work install the app. But it even too him about 30 mins to figure out how to download it. He called the phone number for assistance and the person only spoke possibly Mandrin. He sent an email also and we did get a response in about an hour in broken English with a different website. After downloading the app it seemed intuitive. I set it up for every 20 min monitoring and will see what kind of graph I get tomorrow morning.

Two issues prevent me from getting this past the health department in my state for COVID-19 vaccine storage: 1) The calibration certificate states the device is verified accurate to +/- 0.5 deg C from between -20 to +50 deg C. At -25 deg C, the certificate states accuracy is +/- 1 deg C. Frozen Moderna COVID-19 vaccine is required to be stored at between -25 to -15 C using a monitoring DDL device with accuracy no less than +/- 0.5 deg C. My state interprets that to mean it has to be that accurate in the temp range actually used, not just somewhere on the temperature scale. This means this should work for thawed/refrigerated temp range of +2 to +8 deg C. So in theory it is accurate enough for the fridge but not freezer. 2) The calibration certificate does not provide a manufacture date or calibration date, so this won't work in any event since my State Health Dept requires that. Others have mentioned this too. Fortunately they're returnable so I'm working on finding a rigorous enough device. The cheap price was indeed too good to be true. For uses not requiring those specifications or documentation it is probably great.
