    Features Features Features The Model 275R analyzer has three ranges for purge and normal generator operation, with zero and span potentiometers for each. Each range also has its own scale on the meter face. Efficient insulation around the cell block enables quick restarts so that the instrument can be carried from one generator to the next without a lengthy warm-up period.

  • Page 7: Operational Theory

    (as in chlorine and carbon dioxide gas) indicates that the substance may be a better insulator than conductor. Operation of the 275R analyzer is based on being able to detect the differ- ence in thermal conductivity between the gas being monitored and the known reference (which, in this case, is helium).

    Use 2-conductor shielded cable (nominally #22 ga. wire size) to interconnect the analyzer output signal with any recording equipment. The shield should be terminated on the appropriate terminal (see interconnec- tion diagram) at the analyzer, and be left disconnected at the recorder. TELEDYNE ANALYTICAL INSTRUMENTS...
