Description

The OM-NOMAD-340 portable temperature datalogger features a backlit LCD display for easy viewing of temperature data as well as setup parameters. The datalogger’s waterproof housing makes it ideal for a wide variety of applications. Temperature recordings are started and stopped using the front keypad on the datalogger. Stored temperature data is time stamped via the unit’s built-in real time clock. Data is transferred to the PC using the accompanying download box, RS-232 cable, and Windows software. The software screen includes a window that duplicates the LCD display on the datalogger and shows the real time temperature value, memory status, and battery status. The software also displays the minimum, maximum, and average values of the data set being displayed. Downloaded data can be printed in tabular or graphical format and can be exported as a text or Microsoft Excel file.

Rated 4 out of 5 by from Decent We bought a couple of these, they do a good job of logging data. The graph is not super usable at least in firmware version 1.01. When the temperature is set to Fahrenheit it the graph displays it as 32° lower than it actually is. The graph also really needs a zoom feature that can be either dynamic or user controlled. Right now you can change how many seconds per graph pixel but if you change it it erases everything already on the graph. You can kind of scroll through the graph but this is rather buggy. It would also be great if we could put it into a mode where it logs voltage and resistance directly. Looking at the literature I was under the impression that the RTD would only work for PT100 sensors but in the settings it can be configured for PR200 500 and 1000 as well which I wish I had realized before ordering my sensors. It logs directly onto an included full sized SD card as a CSV file which is well formatted for excel to understand along with timestamps. If you pull the SD card while logging and then re-insert it it will continue logging but will not fill in any data points from the time the card was out. It would be nice if the SD card had a cover over it to prevent you from accidentally popping the card out. The SD card cannot be read from USB, instead a USB serial bridge get's installed that has a few mod-bus instructions allowing you to poll the device for data (including the raw voltage and resistance values) you cannot access any logged values you can only get values in real time. If you plug in or unplug the power the unit continuities working without missing a beat (unlike the HH306A and it's ilk that irrevocably erases all data every time you look at the power connector even though it has a battery and can operate under battery) It comes with a kickstand that feels like it will break soon. I wish it had a tripod mount instead.

Rated 4 out of 5 by from Works great for what it is This is a handy little tool for recording TC's in spots where you don't have any power, just make sure you have fresh batteries in it. Although it has 6 inputs you can only use TC's in 4 of them. You have to have a SD card reader to extract the data as you can't read the logged over a USB cord form the device. The csv file is great for importing into excel and graphing.

Hello, I am trying to use port 5 and 6 and having no luck. (It says you can use two wire PT 100 wire) so I am trying with K type thermocouple wire. should this work? Is PT and thermocouple the same. Please advise great magical one lol thanks

Asked by: LaserMan
Thank you for your inquiry. This model accepts four thermocouple inputs for ports 1 through 4 only, and 2 PT 100 RTD inputs for ports 5 and 6 only. PT 100 RTD sensors are not the same as type K thermocouples. We offer a wide range of PT 100 RTD sensors for you to select from from our website.

The operating temperature is 0-50 C, what is the max safe temperature that the unit can be exposed to without damage?

Asked by: mschulz
Thank you for your question. The storage temp is 60 degrees C. Please contact our Tech Support if we can be of any further assistance. Thanks!

What is the file naming convention? It seems to create a folder w/the create data as the folder name, but inside is a .csv file that looks like DA-XX-YY where XX and YY seem to be random numbers. What is the convention for those file names?

Asked by: LuJR

I'm trying to get information on Modbus communication with this unit and am not having much luck. The communications link in this manual ( https://assets.omega.com/manuals/M5717.pdf ) does not work. Can you point me in the right direction?
