The
RM430 Resistivity Meter and Probe can be used with any DI
Overflow Rinse tank. Just place the sensor in the overflow path and
it will sense the overflow resistivity. As any DI rinse tank fills
with fresh water it will come to a level of resistivity, [somewhat
less than the metered output of the DI system] and as soon as product
is introduced into the tank the resistivity will drop. As the product
is rinsed the resistivity will increase to a certain level, at that
point the product is clean. Either an alarm can sound or the tank can
be equipped with a solenoid valve that automatically shuts off the
rinse ending the cycle.The sensor is placed at the bottom of a
10" filter housing assuring a consistant flood of water and
readings. The filter housing is connected to the outflow port of the
DI overflow rinse tank.
