The OM-70 Series of portable temperature and temperature/humidity data loggers are easy-to use, versatile devices which can be used for a wide range of logging applications including coolers, freezers, greenhouses, museums, laboratories, shipping containers, warehouses, environmental monitoring and food storage.
These data loggers are capable of sampling as fast as once per second or as slow as every 18 hours. Models OM-71 and OM-72 can store a total of 43,344 temperature measurements in memory. Model OM-73 can store a total of 43,344 measurement points for temperature only or 21,672 points of temperature, humidity and dew point. The model OM-74 thermocouple data logger can store 32,638 temperature samples. Easy-to-use Windows software is included with each data logger.
The software is a full-featured program that allows you to set up all data logger functions including sampling rate, logging duration, start mode, logging mode, and high and low temperature alarm values. Once data has been logged, the program then allows you to download data from the logger, plot the data and export the data to an ASCII text or Excel file format for further analysis.
Software Features Include:
• Data summary to read statistics and alarm information in a simplified report format.
• Data listing for tabular view of detailed dates, times and values of recorded data.
• Graph function displays data in clear graphical format.
• Zoom magnifies data with powerful zoom and autoscale functions.
• Autoscale function fits data to the screen or allows user to manually enter their own values.
• Graphical Cursor displays exact data of any point in the graphical display.
• Export data in text or Excel format.
• Print graph or text data with print preview and setup options.
• Logger configuration allows easy set up and launch of data loggers with immediate or delayed start, preferred sample rate, alarm setup, and custom ID.
• Password protected calibration function automatically stores with parameters in device or restores factory defaults. A calibration Window is provided in the software to simplify the calibration procedure.
• Status windows display unique ID of logger, battery voltage, memory used, sample rate, duration, alarm condition and logging status.
• Menu Bar along the top of the screen provides one click access to software functions.

Solid Logger (for the most part)
I have bought roughly 10 of these over the past 8 years. We use them for monitoring the temperature and humidity of a control room for Concrete testing. For the most part these are solid units. I have had a couple that had the screens go out on them after 5 years or so and the plastic gets discolored when exposed to sunlight. One had the temperature go out and it only lets you calibrate it slightly from the original settings. That said these generally work great with those few exceptions. The program for the PC is easy to use and understand. I will continue to purchase these as needed.

works great.
easy to use.
had to guess where to get software to download data to but figured it out eventually.
USB connection works easily, but I would now pay a little mre for a wireless download option

Good for general monitoring
We really like the OM-70 series for monitoring temperature and humidity during our testing. They work well and the software is easy to use.
The only issue we have is that they will not stay in calibration in the lower 10 degrees C of the published range and there is no adjustment to correct this. We calibrate them to 10 C above the published low range and they work well there.

Works as promised
These are great for measuring temperatures in a concrete cure room that we have for ASTM C511.

Good value for a stand alone data logger
I have bought these many times over the years and appreciate the updates to the user interface. The data loggers are very robust and accurate. I would give this a 5 star review if there was a version of the software that would also calculate Heat Index as part of the standard data output. Very useful for safety studies.

NOT A PRODUCT YOU WANT TO PURCHASE!!!!
OMEGA will not support this product. You have to send over $65.00 for the software to operate the product. DO NOT PURCHASE THIS PRODUCT!!!

Reliable instrument
Have one of this working for more than 4 years in a curing room in the middle of the Mojave desert. No problem at all.

Can I log two separate temps continuously with this one unit? Since you discontinued the OM PL-TT I am looking for a replacement.
OM-72 has one internal and one external temperature sensor. Other options you can consider are OM-DVT4 or ISD-TC.
These are not direct replacements of the OM-PLTT, so please read the spec sheets before making your decision. If you have any question please contact our DAS team at das@omega.com or give us a call and ask for the Data Acquisition group.

When Calibrating the logger (per the user manual), is the new calibration stored within the logger itself or in the software app on the PC?
Thank you for your question. Calibration is stored in the logger.
Date published: 2023-05-19
Does the equipment come with a calibration certificate?
Hello, thank you for your question. OM-71 does not include a calibration cert, if a certification is needed then you should order OM-71-NIST instead. This part number includes the same logger plus a NIST traceable calibration.

The data sheet says that the data loggers are compatible with windows 7 and 8 but does not mention Windows 10. Would it work with Windows 10?
Thank you for your question. The software is compatible with Windows 10.

Is the OM-72 approved through the VFC program for vaccine monitoring in refrigerators and freezers.
Hello
I am sorry it is not.

I am looking at the OM-74 for use with a C-type or B-type thermocouple. How many hours do the batteries lasts, are they rechargable?
The battery life could be up to 3 years depending on logging interval and the frequency you connect to PC for setup. It is not rechargeable, AAA alkaline or lithium are used.
Date published: 2020-02-14
Using the interface software, is there any way I can live export data when new points come in, or do I have to manually export every time I want the data?
Thank you for your question. Once the logger has started you can auto-load date to software and then you would have to manually Export to Excel. It will not import real-time into Excel.

Is there a list of serial commands for this instruments? I am looking to communicate with the instrument over serial interface from a python environment.
Thank you for your question. There are no serial commands available just the provided software.
