Remote Data Collectors (RDC’s) are used at every probe location where maximum visibility and sensitivity to corrosion rate changes are required. Readings of corrosion and temperature data may be set as frequently as every five minutes for RDC-COT. Programming of all the RDC's, and data retrieval from the RDC's is accomplished by a single Checkmate™ DL or Mate II for direct transfer to a portable or desktop P.C. running Corrdata ® Plus Software. For non-intrinsically safe applications the RDC may be configured directly from the PC.
