Please check out Newest Released Temperature and Humidity Portable Data Loggers with LCD Display OM-HL-SH Series or OM-HL-SP Series for more advanced features with better price.The OM-90 Series are portable, battery operated,temperature (OM-91) and temperature/humidity(OM-92) data loggers. The OM-90 Series data loggersoffer accurate and repeatable logging for temperatureand relative humidity. Temperature is measured to anaccuracy of ±0.3°C over the range of 5 to 60°C(41 to 140°F) and ±2.0°C over the full range of-30 to 80°C (-22 to 176°F). Relative humidity ismeasured to an accuracy of ±3.0% RH over the20 to 80% RH range and ±5.0% RH over the0 to 100% RH range. Both temperature and relativehumidity are logged at a user configurable logging ratewhich is software selectable.
These data loggers are ideal for transportationapplications where it is necessary to document thatthe material in-transit has stayed within particularenvironmental limits. High/low alarm limits can be setabove or below which LED indicators will be activatedso that the user can become aware that the desiredtransportation conditions have been exceeded.
Each data logger can be assigned a 16 charactername. This can be helpful in applications wheremultiple data loggers are used and there is a needto distinguish between them (for example based onlocation).
The data logger includes a very easy to use softwareapplication. The application is used for configuration ofthe logger, extraction of logger data, graphically viewingdata, spread sheet analysis of data and saving datato file (typically in comma separated value CSV fileformat) for third party applications such as MicrosoftExcel. The graphical user interface is completelyintuitive in terms of configuring new devices andextracting data from a field device. When the user hasmultiple devices requiring the same setup then a loggersetup from a saved configuration file can be preloadedinto the application to help expedite the process andensure all loggers get setup identically. The applicationdoes not require any driver installations to connect tothe data logger. Just install the software, run it and thenconnect the data logger.
