Elitech USB Temperature and Humidity Data Logger 5PCS RC-4H Upgraded, Refrigerator Thermometer, Food Storage Monitor, Cold Chain Recorder with 64,000 Data Points, Auto PDF/CSV

The logger itself is simple and works very well, with a calibration certificate. The downloadable software is really good. For the money this is exceptional value.

My initial impression when unpacking was that it looked cheaply made. One of the battery contacts was bent which meant the battery could not initially be inserted until I had corrected this. When I used it for the first time I realised that this was however excellent value for money and works, hence the reeson for 5 stars. The accuracy is within the tolerances specified, and the software mostly works. No disk is supplied however it was not problem downloading it via the supplied link. I'm using the Mac version on a MacBook Air. The software is not perfect, however it does record the temperatures over time. (for some reason the graph curve doesn't exactly match the temperatures populated in the table). I've also changed the time between measurements and found it doesn't always accept the change, even though it was saved. Overall however it's an excellent tool for giving an indication of temperature changes over time, useful for optimising my central heating, and at a very good price.

I bought this product, and at around the same time another with similar functionality but sold at about twice the price. It's hardly surprising, but perhaps gratifying, that the more expensive product turned out to be easier to use and generally felt and looked higher quality. With that out of the way, I'm happy to report that Elitech data logger does what I bought it to do, which is record temperature and relative humidity in my house. I managed to download the software from the US site, the only issue being that I had to go into the Security settings on my Mac to get it to load; I think this relates to the verification signature on the software being out of date. I like the ability to adjust the data logging frequency. I don't like the fact that the exported Excel data file has the sensor readings formatted as text rather than number, which means an error is thrown when you want to make a plot in Excel. Easily fixed manually in a small data file, but I wouldn't enjoy dealing with two weeks worth of data. General look and feel is a bit dated, both the device and the software. Instructions okay, but felt what I ended up doing was not quite the same as what they told me to do. Functionality is as advertised, and seems to work fine, although I've not done comparisons/calibrations so can't comment on the accuracy. Haven't had it long enough to comment on battery life either. I'd be cautious about using out of doors where rain might be an issue. Would I buy another? It depends on what I wanted to do. For a one-off application where cost was a major concern, probably yes. For a multi-sensor project, like monitoring several rooms and outdoors simultaneously, probably not; I'd go for a product where the software was a bit more up to date in look & feel, and which seamlessly handled data from multiple sensors.

It works perfectly and suitable for what I was looking for. I downloaded the software from Elitech website and figured it out how to set custom intervals etc... easily. No problem so far.

I was looking forward to using this logger to help resolve some humidity issues. I would be looking forward to it if I was able to get some software that works. First off in the pack you get a mini cd with the software on it, great if you have a drive that can take it. A quick scan of the internet then results in the UK Elitech site not being found so no chance of downloading hit from there. Emails asking for Elitech's help are bounced back. I have now downloaded the software from the Elitech US site but still cannot get it to work. Sorry Elitech but what a let down.

Very easy to set up Small and neat Takes a temperature reading at a defined interval. When you want to see the results, plug device into USB on your laptop and it connects to software. Software (supplied/downloaded from web) shows graphs and tables and has good functionality for export etc Seems to be accurate I attached a bit of sticky velcro to it so I can take it off the wall when I want to review the data

The logger itself is good, but the supplied pc software to work with it doesn't work - it won't communicate with the logger. I sent several emails to elitech sales and support but received no reply. So much for customer and product support! *Updated* - Support got back to me, apologised for the delay, sorted out the software and all is working perfectly now!

I wanted a device to track the temperature of my hot water system so I needed something with a remote probe. The unit is very compact and simple to use. Simply press and hold the button to start/stop recording. The unit lets you see some basic recording info on the LCD screen but for proper use you need to install the software. The software is fine but with some quirks (eg you have to press connect before it will talk to the data logger). It's also an 'unknown' publisher which is not great but you can live with that. Once in the application you can set the recording parameters, view recorded data and export to different formats. Exporting to excel was a bit quirky so I used text export and then opened myself in excel. I've knocked off a star for the quirky software otherwise would have given 5 stars.
