Control pH, OD and Temperature with our company control system. Optical Density is automated with measureable optical sensor. pH and Temp electrodes are standard BNC type connections which allow for affordable routine replacement. All controls are custom installed and pre-programmed in a non-metallic weather-proof enclosure. The large size of the enclosure allows for multiple control modules and motor controllers to share a single enclosure reducing the price. The enclosures come standard with a fan cooling system. Wall mounting hardware is supplied standard or the enclosure can be mounted directly to any paddle wheel frame for an RW 2 - 0.5.
