D ) To connect the sample flow to the cham-
ber, place the inlet flow on the left plastic
fitting (with the mounting bracket facing
away from you) and the outlet flow on
the right plastic fitting.
The optimum flow for the Martek
Ultrapure pH Sensor should remain between
45 - 150 ml/minute to avoid a streaming ef-
fect. The Martek temperature sensor or con-
ductivity reference cell must be connected to
the Mark 22 and subjected to the same sample
stream if temperature - corrected pH data is
to be obtained.
