Model CDM-2
Direct reading C O N D U C T I V I T Y METER by RADIOMETER The Radiometer IVlodel C D M - 2 has been designed with laboratory requirements in mind. Without any sacrifice in accuracy it has been made more flexible and simpler to operate than the conventional conductivity bridge—and covers the complete range of conductivities. Direct readings on 12 ranges are displayed instantly on a hand drawn illuminated mirror scale with an accuracy of better than ± 1 % on most ranges and ± 2 % at the extremes of conductivity. A choice of conductivity cells makes C D M - 2 ideal for all normal laboratory conductivity measurements as well as conductometric titrations. Available cells coyer either immersion, flow, or pipette applications—all on grounded or u n grounded media. Output terminals are provided for connection to
recorders for continuous measurement, or to automatic titrators for automatic conductometric titrations. Write for complete descriptive literature and prices. RANGES: (12 complete full scale ranges) 0 - 1.5 - 5 - 15 - 50 - 150 - 500 micromhos. 0 - 1.5 - 5 - 15 - 50 - 150 - 500 mill imhos. Price $390.00 inclusive
