Portable Temperature and Humidity Data Loggers

The OM-90 Series are portable, battery operated, temperature (OM-91) and temperature/humidity (OM-92) data loggers. Logging is performed at a user configurable rate which is software selectable.

These data loggers are ideal for transportation applications where it is necessary to document that the material in-transit has stayed within particular environmental limits. High/low alarm limits can be set above or below which LED indicators will be activated so that the user can become aware that the desired transportation conditions have been exceeded. Each data logger can be assigned a 16 character name. This can be helpful in applications where multiple data loggers are used and there is a need to distinguish between them (for example based on location).

You may also use your data logger in Real Time Logging mode. This is a way to monitor temperature and humidity conditions directly from your PC or Mac instead of using the remote logging.

The data logger includes a very easy to use software application. The application is used for configuration of the logger, extraction of logger data, graphically viewing data, spread sheet analysis of data and saving data to file (typically in comma separated value CSV file format) for third party applications such as Microsoft Excel.

The graphical user interface is completely intuitive in terms of configuring new devices and extracting data. When the user has multiple devices requiring the same set-up then a pre-saved configuration file can be loaded into the application to help expedite the process and ensure all loggers get configured identically. The application does not require any driver installations to connect to the data logger. Just install the software, run it and then connect the data logger.
