RDXL4SD logger is in the end of its life cycle. As a possible substitute & upgrade, please check out Newest Released 8 Channel Thermocouple Data Logger OM-HL-EH-TC Series for more advanced features with better price.
The Handheld RDXL4SD and RDXL12SD models are portable thermometer/data loggers with backlight display and built-in analysis functions. The data loggers are powered by an internal battery and are capable of sampling, processing and displaying measurements without being connected to a computer. With their high resolution and fast analog to digital converter (ADC), the RDXL4SD and RDXL12SD meet the majority of data logging requirements in most industrial applications. Real-time SD memory card data logger, built-in clock and calendar, real time data recorder, and sampling time set from 1 to 3600 seconds comes standard. Data logger can log data manually by setting the sampling time to zero. These real-time data loggers, save the 4- or 12-channels temperature measuring data, along with the time information (year, month, date, minute, second) into the SD memory card and can down load to Excel. The end user can make any data or graphic analysis by themselves.

Great Data loggerGot two of these for temperature profiling of our freezers, very convenient to set up and use these.
This model did not have an AC adapter - which could be handy especially for long term data recording (or redundancy) to prevent data loss due to battery draining out.
Otherwise, this is a great unit for portability and convenience.

Indispensible to our work.We have used Omega thermocouples for over 20 years. We still have some from then that still work.
The data logging capabilities of the RDXL Series is a great value for documenting our work for our customers and in preventing costly failures.
