Description
Description
The OMYL-RH25 is a temperature/humidity datalogger that also accepts two external temperatureor temperature/humidity inputs. This data logger isavailable with standard memory of 100,000 readings(OMYL-RH25) or expanded memory of 4 millionreadings (OMYL-RH25-4M). The following inputs canbe configured:
• Internal temperature and humidity sensors
• External temperature (Pt100/Pt1000 RTD, Type U thermistor)
• External temperature/humidity (for combinedexternal temperature/humidity probes)
The storage medium is non-volatile flash memory so nodata is lost if the battery becomes discharged.Data logger setup as well as data retrieval isaccomplished using the included standardOMYL-SOFT software. Downloaded data is storedin the OMYL-SOFT software as a text file for viewingin third party software packages or Microsoft Excel.The OMYL-SOFT standard software does not includeany graphing functionality. Graphing and analyzingdownloaded data files requires the OMYL-SOFT-PLUSversion of the software (sold separately).
