These Hanna mini controllers have been
specially designed for water conditioning
and growing applications. Compact in
size, they can be mounted in con+ned
spaces or even right next to the vat or
barrel containing the chemicals. These
meters permit automatic control of
installations previously checked manually.
EC measurements are shown on the display
and the multi-colored LED continuously
indicates if the mini controller is in
measurement, dosing, or alarm mode.
Users can choose automatic or manual
dosing mode with a switch on the front
panel. Manual control is particularly useful
during maintenance operations, because
it permits operators to enable or disable
the dosing relay according to need. The
overtime control system advices users
when the relay is active for too long,
helping to prevent overdosage.
