*Specific conductance (conductivity corrected to 25° C), resistivity, and total dis-
solved solids measurements are also provided. These values are automatically calcu-
lated from conductivity according to algorithms found in Standard Methods for the
Examination of Water and Wastewater (ed. 1989).

A mechanical totalizer is available for the 4220 that consists of a
seven-digit, non-resettable mechanical counter mounted in the
front panel. It must be ordered with the flow meter. The totalizer
advances according to program selections for units of measure
and the maximum flow of the primary device used. The totalizer
is internally set to advance at
totalizer. Consequently, you must multiply the number shown on
the mechanical totalizer by 100 to determine the actual value for
total flow.
