Some of the newer instruments, the MS1500E and MS3500E/3510E in particular, perform metal loss
and corrosion rate calculations automatically and display these as a direct reading. These instruments
contain a selectable library of element geometries that, once selected, are automatically fed into metal
loss corrosion rate calculations. Should the user not find the element geometry specific for the
probe in use, he can select any geometry (except wire) of the same thickness in order to
obtain valid results.

Two key performance characteristics for a particular element style are element life and response time.
The element life is directly proportional to its thickness, whereas response time, which is the time
required to obtain a significant reading change at a given corrosion rate, is inversely proportional to
element thickness. Thus, the user must make some compromise between life and response time when
selecting a sensing element. Figures 8 and 9 provide a general guide for selecting optimum life and
response time combinations.

The other major performance characteristic related to element geometry is measurement reproducibility.
Under ideal circumstances the measurement reproducibility will match the instrument resolution, which is
+0.1% for most commercially available units. However, low resistance elements in systems exhibiting
frequent (30-60 minute cycle), and comparatively large (±10-15°F), temperature fluctuation may only
achieve a reproducibility of +0.5%. Such low resistance elements should be avoided when temperature
instability is anticipated, unless high corrosion rates are expected (20+ mpy).
