Rated 5 out of 5 by from So easy to use!!! Let me preface my review by letting you know that I am an engineer employed at a large and very well-known chemical company. I purchased this data logger a few weeks ago to log pressure in my plant's fire water piping system. I have used many different data loggers in the past, but this one is by far the best and easiest I have ever used. My only complaint is that this data logger does not have a built-in power supply; however, considering how small this data logger is in comparison to others with an interactive visual display, how can I really complain.

Rated 4 out of 5 by from Temperature Testing Overall impression is good! It is super easy to use, I did not even require the manual to get up and testing in 5 minutes. My only complaints are battery life for long data logging tests (you can leave plugged in to wall outlet just wish the battery lasted longer), the plug in connectors are a little difficult to install and remove, I wish I could view all channels at the same time on the graph, I wish I could adjust the scale of the graph and finally I wish it could record more channels.

Rated 4 out of 5 by from Field Engineer I bought this about two months ago and overall have been happy with it. There were a few times I had an error with programming when turning it on but was able to quickly fix the issue by just resetting it and have been able to log several different parameters and get the results I needed to. It coupled well with some of the pressure and temperature sensor we had available and the data and time stamping seemed accurate and easy to export. I think that this is a good versatile data logger for monitoring industrial issues.

Rated 1 out of 5 by from Tons of promise wrecked by poor UI and a buggy OS We needed a product to use on the road for some basic logging - some 4-wire RTD's and some analog channels. This seemed like a great way to avoid headaches for temporary setups. We've got a deep well of trust for Omega, having used Omega stuff for years and years. So this was a shoe-in. Out of the box, all was well. The interface draws a lot from modern smartphone conventions, which makes it super intuitive to figure out - I was logging 2 minutes after I opened it up. In the field though, things began to fall apart. During setup it would occasionally freeze up and need a power cycle. Fine, normal, but the power cycling takes a very long time (2-3 minutes at least) and the device doesn't tell you if it's turning off, turning on, if you've pressed the button long enough, etc. This was surprisingly frustrating. Many selections made on the touchscreen (such as reading interval) feature a "poke and pray" scrolling list, which would be too hard to use even on the newest phones. The screen itself has to be the poorest capacitive screen I've ever used. It almost feels like one of those old resisitive ones. Data cannot be removed during a logging session. Not a big deal, unless combined with the last and largest issue... Getting the thing to recognize a USB stick (including the one it comes with) is madness. Reboot, reboot with it plugged in, try a different stick, take it back to your PC and format it, reboot again, and MAYBE this time it will recognize it. It's an excellent toy if you want to mess around. But if data is equal to dollars, stay far away from this product.

Rated 1 out of 5 by from Completely broken after a few uses the analog board blew out according to an error message on the display after using only a few times. It was measuring fine but ended up just stopping and I haven't bee able to start it back up since then. It appears to be a $1000 broken piece of equipment. I'll see what Omega does to help fix this situation.

Rated 1 out of 5 by from JUNK! Great design, poor execution. Touch Screen Problems: The touch screen is very unresponsive and sluggish. Also, when typing you will have to touch a bit higher on the screen to get it to press the correct button. There's no way to calibrate the touch screen that I can find. Typing a six letter word will take about 15 seconds with the extremely slow response time. USB Problems To transfer the data files off the unit you will need a thumb drive or a USB-C cable to connect to a computer. The majority of the time the handheld doesn't recognize when you plug a thumb drive in. The only way I've found to get it to recognize it is to reboot the unit, usually several times. I tried to use the cable and connect to a PC with zero success. I updated the software on the PC to the latest version and still no luck. With the exception of these two critical flaws, when you can get it to work it does have some great features and would make an awesome data logger if the execution would've been better. Shame on Omega for releasing this garbage knowing full well of these issues.

Rated 3 out of 5 by from Logger impressions after initial setup and use This device is very simple and functional, but has several shortcomings. The touchscreen sometimes is very insensitive and other times double hits, but it is useable. The data graph is very basic with very limited scaling and only 2 channels displayed. This device is adequate, but was expecting amazing at this price point.

What are the power requirements to keep the unit continuously powered? The battery life is far too short for a semi-permanent installation.

Asked by: DonW
Assuming that I don't have a 120 VAC plug in handy inside of the controller where I'd need to install the logger though, I'd need to provide power another way. I assume that it's expecting 5V on the USB circuit, but how much amperage will it draw? I can provide 5V more easily than 120V, but I'd still need to know the load.

There is one issue that continually comes up, in that it doesn't recognize a USB stick when inserted, so it is difficult to transfer the data off of the unit. Is there a workaround or firmware update available?

Asked by: James2
Thank you for your question. Please note that the USB drive should not be inserted until the OM-CP-OCTPRO is fully booted. If the USB drive is inserted before the OM-CP-OCTPRO is started, the drive will not be recognized. Please wait until the device is running, and then insert the USB drive. If you have further issues please e-mail DAS Engr-DAS@OMEGA.COM.

Channel 9 details? The manual is not clear on how ch 9 is connected to the system, just says "Port 9 serves as an alarm output". Are there any other details available (voltage, current limits, etc.)? Need to determine what, if anything, can be connected.

How often is calibration recommended? Aside from standards is there a manufacturer time frame for this?

Asked by: JEng
Thank you for your question. With all of our loggers, we recommend calibrating every year. However, this is not any sort of official specification or requirement; this is just our general recommendation. How often a user has the device calibrated will depend on their specific accuracy needs, any regulatory requirements they need to conform to, etc. So, ultimately, how often they calibrate the device will be their decision.

I would like to use thermocouple(Fine Gage, Single Strand, Insulated Thermocouple Wire) type-T with this device, should I buy additional connector or adapter?

Asked by: Ian C
Thank you for your question. The logger accepts stripped leads attached to screw terminal adapter that is included.
