OMEGA OMYL-RH23 Series Data Logger

Manufacturer: Not Provided
Measurement Category: Meteorological, Condition Monitoring
Operating Environment: Dry Enclosed Space
Version(s): OMYL-RH23/OMYL-RH23-4M: Internal temperature, humidity and pressure sensors
OMYL-RH23E/OMYL-RH23E-4M: Internal pressure sensor with temperature and humidity sensors fitted in integral probe
Communication Protocol: Internal Logging
Operating Mode: Stand Alone
Power Supply Type: Battery
Power Specification: 3V lithium battery; user replaceable; optional high temperature range battery available


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 or expanded memory of 4 million readings. The storage medium is non-volatile flash memory so no data is lost if the battery becomes discharged.
