EC Mini Controllers Measuring in μS/cm

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.
