Please check out Newest Released Temperature and Humidity Portable Data Logger with LCD Display OM-HL-SH Series for more advanced features with excellent user experience.

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.

Is this data logger completely portable? Meaning, when used in an autoclave, does it require a connection to a computer? Or does it simply get removed from the autoclave and downloaded onto a computer following completion of a cycle?

Asked by: Kaitlyn
Hi, thanks for connecting with Omega. The OM-CP-HITEMP140 logger series requires a docking station OM-CP-IFC400 (sold separately) to interface with the computer. You would use the computer only for set up and to download data. After removing your logger from the autoclave, please allow it to cool down and clean it with a dry cloth before placing it in the docking station. This is really important as the docking station is not designed to withstand the autoclave operating conditions.

I use Linux, not Windows. A few Qs: 1. What is the default setting for sampling rate? 2. Will the device appear as a storage device if plugged into a Linux kernel? 3. If yes to 2., will the .txt data file appear on the device? Thx

Asked by: Cam W
Thanks for your questions. Unfortunately, the OM-141 (or the OM-HL-SP) will not support Linux since both logger’s software is designed for Windows. However, we can recommend the product OM-HL-SP, the max logging rate is 1 sec and the default is set to 60 secs. Please contact us anytime with further questions.

What is the fastest sampling rate?

Asked by: Simon
Thank you for connecting with Omega. 1 sample per 2 secs is the fastest sampling rate which is depend on the RF reader.
