  • DeFelsko PosiTector Dew Point Meter Loggers

    DeFelsko has done it again!  Now with an enhanced second version, their Dew Point Meter Logger instruments are award winners for remote monitoring of environmental conditions.

    Both PosiTector DPML models offer the ability to continuously monitor climatic conditions remotely.  Both offer wireless connectivity to the PosiTector app.  Data from both is uploadable to PosiSoft for generating reports.  And now, the new DPML+ offers all the features of the original DPML, with 2 key upgrades, as follows:

    • AAA battery power, providing enhanced recording time.
    • WiFi enabled, offering continuous uploading of data to the PosiSoft software AND email alerts to users when climate conditions fall outside of user-defined limits.  

    Enjoy the greater peace-of-mind offered by the DeFelsko DPM-L series with autonomous recording and reporting of the climatic conditions over the life of your projects.
