The OM-EL-USB Series of data loggers includes models for temperature, temperature/relative humidity, voltage, and current measurement. The user can easily set up the data logger and download the stored data by plugging the module into a PC"s USB port and running the easy-to-use Windows software. Software-selectable setup parameters include logging rate, start-time, high/low alarm settings, and temperature units (°C or °F). Data can then be graphed, printed, and exported to other applications such as Excel. Each data logger is supplied complete with a long-life lithium battery. Built-in LED indicators show data logger status. OM-EL-USB Series data loggers are protected against moisture to IP67 standards when the protective cap is fitted.

Cool Product.
Very easy to set up. I was able to follow the instructions and have the loggers ready to go very quickly.

Excellent value, does what was advertised
Easy to use logger, software provided on a CD.
Pros very easy to use program, small unit, Omega's service is excellent
Cons, the usb cover on one unit split just from putting it on, but I think it's more for looks than protection. If you don't have a CD drive that could be a problem. The logger must be restarted every time you read it so you can't get short term readings out of it and have a long log at the same time.
Not a pro or con, the program allows you to set the logging frequency to times as short as 10 seconds. I almost can't imagine the sensor being able to register an air temperature change though it's case, in that short time.

Great results with zero setup
Have been collecting battery discharge data every 5-minutes for two weeks with no problems, no setup and great graphical results.

Poor Battery - Doesn't work in Freezer
The battery died within 48 hours of being in a -20 freezer. The device is advertised to work down to -35C. Not as described at all.

A fine addition to a Quality Engineer's toolbox
I needed a data logger to better understand the ambient conditions of in-process product, final product in storage and final product in transit to our customers. The OM-EL-USB fit the need perfectly.
And software is simple, effective and free.
Overall, an outstanding product. Thank you Omega.

Good Sensor/logger Package
Simple and easy to use software, but provides enough flexibility to allow for delay deployment, and high/low alarms. I have the temp and humidity version. Two currently installed in an outdoors environment, but semi-protected from direct rain and sunlight. Time will tell how they will hold up, but not really designed for using outdoors. So far, very happy.

I have an om-el-usb 1lcd. I have download the software but am unable to get the software to find the usb stick. i't won't install the usb driver
Thank you for your question. A low battery under 3.6 volts is a possible connection problem and driver install is being prevented by PC security/firewall. If problem still persists please e-mail DAS Engr-DAS@OMEGA.COM

Hello! I would like to know what the temperature and RH accuracies are, as I can't seem to find the specs anywhere. Thanks!
For temperature: ±0.3°C (±0.6°F) and for Humidity Range: ±2.0% RH (for 20 to 80%)
Thank you.

How often do these need to be calibrated and how much is it to calibrate them?
Calibration is not economically feasible. If units read out of tolerance than it is best to trade-in for new and get a 20% discount.
Thank you.

Can this be used in a water bath or sanitation parts washer?
Thank you for your question. The logger is not designed to be submerged in any type of fluid. It is designed for ambient temperature.

Hi, I would like to know if is there an alert when the batteries are low? Thank you
Thank you for your question. Led will flash orange every 60 seconds when voltage drops below 3.3 volts.

I have several OM-EL-USB-1 but the software seems to not be compatible with 64 bit PC. Do you have updated software for contemporary PCs? Thank you
Thank you for your question. The version 7.5 Easylog software download from the product page is compatible with 64 bit PC.

Hello, I am interested with the OM-EL-USB-2 sensor. It is specified that it works with Windows 2000/XP/Vista/7 (32- and 64-bit). Will it also work with Windows 10 Enterprise? Thanks.
Thank you for your question. Windows 10 is fine. Windows Enterprise may be an issue because of company security.
