The OMYL-RH23 and OMYL-RH23E are robust devices capable of logging temperature, humidity and barometric pressure readings and are software configurable to record either all three of these parameters or just individual variables. These data loggers are available with standard memory of 100,000 readings (OMYL-RH23, OMYL-RH23E) or expanded memory of 4 million readings (OMYL-RH23-4M, OMYL-RH23E-4M). The OMYL-RH23/OMYL-RH23-4M have built-in sensors for temperature, humidity and barometric pressure. The OMYL-RH23E/OMYL-RH23E-4M have an internal pressure sensor with the temperature/ humidity sensors fitted in an integral 100 mm (3.94') steel probe. These data loggers are suited for a variety of applications including environmental or climate studies, meteorological research and also in clean rooms and laboratories.
The storage medium is non-volatile flash memory so no data is lost if the battery becomes discharged. Data logger setup as well as data retrieval is accomplished using the included standard OMYL-SOFT software. Downloaded data is stored in the OMYL-SOFT software as a text file for viewing in third party software packages or Microsoft Excel. The OMYL-SOFT standard software does not include any graphing functionality. Graphing and analyzing downloaded data files requires the OMYL-SOFT-PLUS version of the software (sold separately).

Overall good pieceGood piece for the money. Manual wasn't that thorough, but there isn't much about the product to be thorough about, it's fairly straight forward for the most part. My only question was how, if possible, to stop the machine from running. There are three options on how/when to start recording, but it doesn't say anything about stopping it, unless you plug it in to the computer. If that is the only way to stop the testing, I feel that is a design flaw. Otherwise, great piece of equipment.

Convenient recorder but software dependentSeems to be a nice data recorder, but you can’t do anything with it without loading the Omega software on your computer. If you work in a setting that requires IT approval for that sort of thing, or want to easily share it between multiple users, that could be problematic.

Great for concrete monitoringWe use these devices to monitor concrete temperatures during the first 5 days of curing. Great for saving heating costs when the internal temperature shows it is above the requirements
Thank you for your inquiry. It comes with a free certificate of conformance. If you need a calibration certificate, you would need to buy the OM-EL-USB-TC-LCD-NIST instead.

Does this thermocouple logger display compensated temperature readings? The manual and product details do not clearly indicate whether cold junction compensation is performed via dedicated circuit when converting voltage to temperature.
Asked by: DavidL
It is not mentioned in the specs, though generally for our thermocouple loggers / monitors, cold junction compensation is built in to the circuitry and performed when converting voltage to temperature.
