34 UDA2182 Universal Dual Analyzer Product Manual January 2009
The UDA also supports Pharma Europa (PhEur) section 2.2.38, which specifies tests for
determining Highly Purified Water which are identical to USP Stages 1, 2 and 3. PhEur
adds a less demanding test for determining Purified Water at the end of the sequence.

Figure 5-5 Pharma Display screen example
5.8.4 Displays
The upper left portion of the screen shows the measured temperature uncompensated
conductivity of the solution in uS/cm for Stage 1. For stage 2 and 3 it displays the test
conductivity value entered during the measurement in stage 2
The process temperature is shown in the upper right of the screen
The lower right portion of the screen shows the USP stage 1 purified water limit, the
stage 2 limit of 2.1 uS/cm and the stage 3 purified water test limit at the measured pH.
When the Pharma n display window is active the various stages can be accessed through
the pharma op panel. (Table 5-6)
