Measuring instrument for measuring and processing characteristic quantities of the environmental atmosphere, particularly below ground

摘要

In a measuring instrument (10) for measuring and processing characteristic quantities of the environmental atmosphere, particularly below ground, comprising a current source (21), a measuring arrangement (22), an operating unit (23) and a display unit (27), written recordings and, particularly underground, the keeping and carrying of an air log can be dispensed with since a memory unit (13) for storing the measurement values of the respective characteristic quantity is provided and connected to the measuring arrangement (22). Measurement values stored in the memory unit (13) can be transmitted to a central processor in which they are then evaluated, but a pre-evaluation, for example a normalisation of the measurement values, is also possible in the measuring instrument (10) itself, via a normalising stage (25).
