The Lufft OPUS 10 recording thermo/hygrometer is a portable, compact and completely self-contained instrument providing both current and long-term measurement of air temperature and relative humidity. The unit will easily and quickly mount to a food storage area's wall surface or serve as well as a stand-alone shelf-top instrument. The large, easy-reading LCD simultaneously displays both current temperature and current relative humidity readings. A third display segment serves as a digital clock. Use of the SmartGraph software with the OPUS 10 thermo/hygrometer allows control of data interval and duration as well as a selection of graphic computer screens with printout of recorded readings. The resulting temperature and humidity profile allows a permanent record of environmental storage and operating conditions over the selected time frame.
