1. A device for gathering information on enviromental conditions, comprising:

  • a portable base;

    measuring means on said base for detecting the magnitudes of selected environmental parameters;

    chronometric means on said base;

    storage means on said base coupled with said measuring and chronometric means for registering a detected magnitude of a selected one of said environmental parameters together with the time of detection on a recording medium;

    coding means on said base for additionally registering on said recording medium the location of a device at the instant of said detection; and

    adjustment means interposed between said measuring means and said threshold means for modifying a detected magnitude in light of other information, said adjustment means including means for selecting among parameter-specific items modifying information for a particular one of said environmental parameters and thereby modifying the detected magnitude with the selected information and for changing said items among which selection is made.
