Works great, PC required

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.

Hardware works like a charm; software's somewhat kludgey

Purchased this to monitor temperature and humidity in my lab. Was looking for something that was compact, wireless in the sense of not being hard-wired but NOT capable of RF transmission, and a fairly sizeable memory. It comes with a holder that can be mounted to something secure and locked in place. Downloaded the software from the company's website and it installed without issue on my Win7 computers. All configuration must be done through the software, which is kludgey in some regards. You synchronize the logger's clock with your computer's and configure the logger's sample rate and alarm conditions. It does have a battery monitor. As time progresses, we'll see how it works. It doesn't give you any information other than a picture of a battery segmented into quarters. No time estimation until dead which would be a nice feature to let you know when the battery needs replacing. The klugey part is how you enable logging. You have to go through a configuration setup every time you want to start logging. With the temperature/humidity loggers I've worked with in the past, you configure the device once and then download/erase/restart logging through separate commands. With this unit, you download the data through a separate function and then must go into the configuration screen to erase and restart recording. Not that big of a deal, just different. The downloaded data is saved in two files - one, in the native format of the logging program and one in Excel format. The formatting of the Excel file needs some massaging in order to graph the data nicely, but quite do-able. The unit is on the spendy side, but it does what I want, so I'm happy with the purchase.

Easy to use and good quality

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.

Non l'ho ancora potuto utilizzare perchè il programma non si carica.

Non l'ho ancora potuto utilizzare perchè il programma non si carica. Prima ancora: l'avevo ordinato circa 2 mesi fà ma il primo Datalogger non è mai arrivato. Devo dire comunque chje Amazon si è adoperato a dovere rispedendomi un altro Datalogger. Come detto ad oggi non l'ho potuto ancora utilizzare. Chiamerò la Extech per aiutarmi in merito. La mia valutazione è complessiva rispetto a tutta la vicenda ed al fatto che, ripeto per l'ennesima volta, non l'ho ancora utilizzato. Il rammarico è maggiore perchè avevo cercato uno dei migliori rispetto al prezzo-qualità.

Guter Logger

Wird verwendet, weil Mieter über oberflächliche Feuchtigkeit klagten. Der Logger kann im 1/2 Minuten-Takt Temperatur und Luftfeuchte messen; der Speicher reicht bislang für einige Wochen aus. Die Daten sind passwortgeschützt und können nur mit korrektem Passwort ausgelesen werden. Anhand der Daten kann das Lüftungsverhalten dokumentiert werden. Gut für eine allfällige Beweissicherung.

Battery dead on arrival

The device itself is fine, and the packaging is fine, but the battery appeared to have been dead for some time now. We cannot use this and am looking to buy a battery to replace it

Fácil de usar

El instrumento funciona correctamente, es fácil de configurar y descargar los datos. La visualización de los elementos gráficos de Temperatura, RH, Dewpoint son adecuados, además se pueden exportar a una hoja de cálculo.

Solid, reliable, changeable batteries

4 stars because one of the 4 units I ordered was dead on arrival. I have not yet contacted the manufacturer to have it replaced. Otherwise, solid loggers with good supports, and easily replaced batteries.
