The OMYL-RH25 is a temperature/humidity data logger that also accepts two external temperature or temperature/humidity inputs. This data logger is available with standard memory of 100,000 readings (OMYL-RH25) or expanded memory of 4 million readings (OMYL-RH25-4M). The following inputs can be configured:
• Internal temperature and humidity sensors • External temperature (Pt100/Pt1000 RTD, Type U thermistor) • External temperature/humidity (for combined external temperature/humidity probes)
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).

Are there temp/humidity sensor options that allow for a real-time export of the data or a configurable XML output to a local port?
Asked by: JoeS
The logged data from the OM-EL-WIFI unit can be imported to EXCEL after it is displayed on PC. You cannot import real-time.

is there a calibration certificate coming with instrument, and If so, is it traceable to ILAC-MRA standards?
Asked by: paulo
Hi, thanks for connecting with us. The calibration certificate is an additional purchase. If you order this at the time of purchase, it would come with the logger. Yes, our certificates are NIST traceable as well as traceable to ILAC-MRA standards. MDQ Calibration Laboratory is accredited to ISO 17025:2005 by PJLA which is an MRA Signatory of ILAC. The insignia for both ILAC-MRA and PJLA are included on our calibration certificates. Please contact us if you have any further questions.
