The OM-DVTH temperature/relativehumidity data logger with display isan easy-to-use, versatile devicewhich can be used for a widerange of logging applications.The OM-DVTH records andinstantly displays trends fortemperature, humidity and dewpoint. With the OM-DVTH you canmonitor real time measurements forinstant environmental conditions.

When you’re ready, download over40,000 data points to your PC forfurther analysis. Data logging hasnever been this visual.The OM-DVTH is capable ofsampling as fast as once persecond or as slow as every 18hours. A total of 43,344 temperaturemeasurements can be stored inthe data logger memory if onlytemperature is measured, or 21,672measurements for temperature,humidity and dew point if all threeparameters are measured.

Easy-to-use Windows software isincluded with the OM-DVTH. Thesoftware is a full-featured programthat allows you to set up all datalogger functions including samplingrate, logging duration, start mode,logging mode, and high and lowtemperature and relative humidityalarm values. Once data has beenlogged, the program then allows youto download data from the logger,plot the data and export the data toan ASCII text or Excel file format forfurther analysis.
