RHT10 Humidity and Temperature USB Datalogger with 16,000 Data Point Memory, Dew Point, Time/Date Stamp, Long-Term Environmental Monitoring

I bought this Data logger to log temps for Freezers, Ambient Car Temp (in the summer) and various other applications. Its very easy to use, Windows Interface works without complication for downloading and graphing Temp, Dew Point, Humidity. Software only works in Windows, but will work under VMWare Fusion (or Bootcamp / Parallels). This unit was bought used and but was in brand new condition (it appeared it had never been used) - very happy with this transaction and product. Only drawback I saw was when you download the data, it quits logging new data. You have to reset the logger (and clear its previous logs) before starting a new log. You can't "spot check" the temp and then return it to keep collecting data... other than that, its an awesome product.

Muy buen equipo

I wanted to keep track of the temp & humidity in my garage prior to installing a exhaust fan. The unit is well built and comes with several useful accessories. From the front panel you can see current/max/min temp & humidity. You need to connect it to a PC via USB to set the unit's date, time, and logging options. The software installed fine on my Win 7 64-bit PC. I downloaded the latest version from the Extech website. The software works surprisingly well. I was able to quickly set up a logging schedule, set the time on the unit, and switch to Fahrenheit. Many logging options are available, from 1 sample per second (max 4 hours, 32 minutes) to one sample every 24 hours, and everything in between. I used one sample per minute which will last 11 days 8 hours. You can have the unit stop logging after it collected the max # of sample, or overwrite the oldest data. It records temp & humidity simultaneously. After a week of of logging, I connected the unit to my PC and was able to download the data quickly and display it in graph or spreadsheet form. If you export the data to a file, it is a tab separated file, and can be opened in a spreadsheet. Each timestamped (m/d/y h:m:s) temp & RH reading will be in the file. The graphic display can't be saved by the program, but you can screen capture it. Data can also be stored in a propriety format for reading into the software later. On the not-so-great side, You can't do much from the front panel, like change from Celsius (factory default) to Fahrenheit or setup logging, or view previous logs. User manual is sparse (-1 star) and a little helpful. If you're not handy with a PC, this unit may not be for you. The front panel display is a bit confusing, there's some data there I don't understand. No backlight. The battery is one of those expensive non-rechargeable camera batteries, a standard 9V or AA, AA would have been nicer. There are two tiny (easy to lose) screws holding the battery cover in place, but the screws go into a metal sockets, not plastic - thank you Extech for that. The battery cover also looks to be environmentally sealed. Overall, I'm very happy with my purchase and recommend the RHT20.

I bought this in April 2013 to track temperature & humidity in my safe. Every 2 months, I pull it out of the safe, plug it into my Windows (Vista 64) computer & download the data. Once I have saved the data, I run the setup which ensures the settings are the same, unplug it, press the button on the side, put the clear cap back on, & put it back into my safe.. I have been doing this since I bought it & it always provide good data. It does exactly what I bought it to do so I am 100% satisfied.

I bought this specifically for work, to make sure our testing labs are within spec for temp and humidity (I work in R&D). It is very easy to program, very easy to get data off of. The only criticism was that it took a little bit of messing with the data to straighten out the timestamp format to be how I wanted it, but that's not a big deal. This was a great price for a little longer like this. There's no better way to go to your boss and say "we need to replace the HVAC system" than to have a beautiful capability analysis and I-MR to back up claims of it being "weird and not good" in the room.

The software comes on a small 80mm CD which Windows 10 could only read on the fourth try. I installed the USB drivers and software application easily, but it did not create a desktop icon. I found an Extech folder in Program Files (x86). Windows Defender at first prevented DataLogger.exe from running. Once beyond that, it gives you four buttons: Connect, View File, About, and Quit. Selecting Connect (with the RHT10 plugged in to a USB 2.0 slot) brings up a blank window with menus. Selecting Link/Logger Set brings up a parameter-setting window, with the title that starts as "Connecting..." and changes after a moment to "Connected". Sounds great! However, setting a few parameters and clicking "Setup" pauses for a few seconds, and then the title changes to "Connected (not responding)". No action I tried would get the hardware and software communicating, except if I unplugged the RHT10, a popup announced "Datalogger Disconnected!". Ugh! Finally, on the 14th attempt to Connect and Setup, it worked, and I got the "Press Orange Button to begin" popup. This may be an excellent piece of hardware, but the software seems amateurish at best.

Was having issues in laboratory and office at work, so bought these items to monitor temp and humidity. It does as advertised, but the managing of the data is somewhat annoying. Instructions are basic, but not completely clear. Would not install on a Windows 7 computer, but works with XP just fine. You have to set it up every time you off load data. It doesn't automatically restart. Off loading the data doesn't clear it, and it will not restart on its own. Just a minor annoyance. You cannot rename the device, so if you have multiples your are trying to manage, you have to be careful not to mix them up.

Great tool for collecting temp and humidity data inside a room.

Piccoli facili da usare e affidabili

Kunde inte installera drivrutiner i Windows 11. Kan inte sätta grundlägg konfiguration direkt på enheten. Skickade tillbaka som dag.
