Features
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 logger
Got 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.

Very versatile temp data logger
Very versatile temp data logger that can handle different types of thermocouple. Can sample at various times and log onto an SD card and easily be viewed in a spreadsheet.

Nice data logger, easy to use
Purchased for manufacturing operations. Works great and easy to use. It has a 3 week leadtime but on time to commitment.

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.

Where can I get a 9V power supply for this unit? I got the unit hot and now the battery compartment is warped.
The AC Adapter for the RDXL4SD is the ADAPTER-SD and is sold as an accessory.

Can this model display max/min for ALL 4 channels simultaneously?
Yes, the meter will display all four channels.

I need thermocouples that can be exposed to direct flame. Which ones would be compatible to this device?
Thank you for your inquiry! You can use bare thermocouple wire rated for the appropriate temperature range to directly measure the temperature of a flame. However, if you plan to measure for an extended duration of time, it would be best to select a thermocouple probe for durability and repeatability of your measurements. Lastly, the thermocouple you choose should have a mini connector to connect into this data logger.
Date published: 2021-05-31
Will the data still be logged after starting the REC and then powering off the unit? Or does the display need to stay on for the logging to occur?
The Logger should be left on when in record mode. When in record mode the meter enters into a low power consumption operation until recording is terminated.

RDXL 12 SD do you have a calibration manual???
Thank you for your inquiry. We believe the best assistance would come from speaking to us directly at 888-826-6342 ask for the Temperature Department Mon. – Fri. (HOURS 8:30AM - 5:30PM EST).

When recording data does the auto off feature need to be (no) or can it be left in auto off (yes)?
Once in record mode the logger will not turn off until it has the recording ended. So it would ignore the APO setting.

Good morning, Devise: RDXL 12SD Is it possible to apply a different Offset on the 12 channels? What method? * Type K and J thermocouple
The offset entered on the RDXL12SD will be for all channels not individually.
Date published: 2024-04-26
Besides the Temperature Offset, can this unit be calibrated. For example can the A/D converter be calibrated with a precise mV source. If not, what is done when buying with a NIST traceable certificate "-CAL"
The Logger can be returned for a NIST calibration but the procedure is proprietary and not available to send out.
