The CHEMTROL
CT3000 controller is a fully programmable controller designed for complete chemical automation (Conductivity, pH and ORP) as well as control of chemical additives
(inhibitors, biocides, dispersants, etc.), water level, and influent/effluent pressures in cooling
towers, boilers, and waste water, all with full remote duplex capability. The user-friendly eight-line Main Screen display enables the operator to supervise all the process functions at a
glance and to quickly respond to any changing condition with choice of operating language (English, French and Spanish) and units (US or metric). Entries are made on the 16-key keypad
on the front panel. Â Each unit is supplied with a full 40-page instruction manuals with schematics of installation and menu flow charts.
All CHEMTROLcontrollers are covered  with a FIVE-YEARelectronics warranty backed up
by our network of factory-trained Qualified Dealers.

The CHEMTROL
CT3000 controller operates like a computer with full-screen displays and direct access to all menus and submenus. The front panel keypad is used to move up and down each menu
and enter or exit the submenus. All operating functions can be easily modified from the keypad, including sensor calibration, control setpoints, alarm levels and the different feed programs.
