Extech 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.

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.

Great item, works well in a remote location as a data logger. I use mine in the crawl space to capture humidity readings to decide if I need or want to invest in a de-humidifer for a crawl space. The crawl space de-humidifer's can run a grand or so. So this device is a great device with minimal investment before committing to a larger investment.

Excelente dispositivo, de fácil manejo y práctico. Permite el monitoreo de acondiciónese ambientales de una manera precisa y sencilla. Con análisis de datos gráficos y en tablas! Muy útil.

This unit is good for remote monitoring as it has a built in battery that allows is to function without a PC. It does not function well as a PC connected unit as it does not use or charge from the USB port. Reading temperature requires downloading data, which stops measuring. The graphs, save to .xls or .txt are attractive features. The application is a minimal load for the PC as opposed to the EL-USB-RT which can put a disruptively large CPU load. There must be better options for monitoring temperature through a USB port for same room temperatures.

I had a new refrigerator that would fluctuate in temperature radically. I've used USB data loggers at work before for various reasons and thought buying one and installing it in the fridge would provide a data record that I could show to the warranty repair company to help diagnose the on-going problem. I purchased the EXTECH RHT10 expecting the same reliable results as the EasyLog USB data logger I use at work. When I tried loading the provided software, It would not load. Finally after the 3rd time of trying, it finally loaded. I put the data logger in the USB port and my PC indicated that it was not connected. Then logger then seemed to connect and disconnect every 5 seconds. After a reboot and another try, I was finally able to connect and set up the logger. After setting it up, I disconnected it, started it (watched the LED blink every time it took a reading) and set it in the fridge. After a week, I plugged it into my PC only to get a message that the logger had zero data! It then started it's connect/disconnect sequence again. It's bad enough that this product didn't work, It's worse that it lost vital data. Bottom line. Buy a better product and test it several times before recording vital data.

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