Discontinuous indication

{
  "id": "MLC-T-CHM-003279",
  "term": "Discontinuous indication",
  "field": "Chemistry",
  "definition": "An analyser reading that relates to the sample concentration only during separated intervals of time, so the output is refreshed in steps and not followed without a break. A gas chromatograph, for instance, reports a new value once per analysis cycle, perhaps every few minutes. It contrasts with a continuous indication, which tracks the sample concentration permanently, though a time lag may exist.",
