MICROtron Controller Four Selectable Feed Timers

Description:

The MICROtron is a compact, four relay microprocessor-based controller with many standard features. MICROtron models are available to control conductivity and three selectable feed timers, or four independently programmable feed timers.
The MICROtron platform provides an economical option for conductivity control of a cooling tower or other recirculating water system. Selectable feed timer options include: pulse, 28-day, recycle and post bleed, with bleed.
