OMYL-RH23_OMYL-RH23E

The OMYL-RH23 and OMYL-RH23E are robustdevices capable of logging temperature, humidityand barometric pressure readings and are softwareconfigurable to record either all three of theseparameters or just individual variables. These dataloggers are available with standard memory of100,000 readings (OMYL-RH23, OMYL-RH23E) orexpanded memory of 4 million readings(OMYL-RH23-4M, OMYL-RH23E-4M). TheOMYL-RH23/OMYL-RH23-4M have built-in sensorsfor temperature, humidity and barometric pressure.The OMYL-RH23E/OMYL-RH23E-4M have aninternal pressure sensor with the temperature/humidity sensors fitted in an integral 100 mm (3.94")steel probe. These data loggers are suited for avariety of applications including environmental orclimate studies, meteorological research and also inclean rooms and laboratories.

The storage medium is non-volatile flash memoryso no data is lost if the battery becomes discharged.Data logger setup as well as data retrieval isaccomplished using the included standardOMYL-SOFT software. Downloaded data isstored in the OMYL-SOFT software as a textfile for viewing in third party software packagesor Microsoft Excel. The OMYL-SOFT standardsoftware does not include any graphing functionality.Graphing and analyzing downloaded data filesrequires the OMYL-SOFT-PLUS version of thesoftware (sold separately).
