Temperature, Humidity and Barometric Pressure Data Loggers
- This product line has been discontinued. For an alternate product, please see our wide selection of temperature and humidity loggers here. For pressure dataloggers, please see our selction here.
- Integral Temperature/Humidity/Pressure Sensors
- OMYL-RH23 Has Internal Temperature/Humidity/Pressure Sensors
- OMYL-RH23E Has Internal Pressure Sensor with Temperature/Humidity Sensors Fitted in Integral Probe
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).
