Chemtrol PC1500 ORP/pH Programmable Controller – Advanced Digital Water Chemistry Control

The Chemtrol PC1500 sets the industry standard for sophisticated, fully programmable ORP and pH control. With advanced microprocessor-based operation, it provides precise sanitizer and pH regulation while offering easy setup, clear menu navigation, and flexible control modes. It's the ideal solution for pools, spas, cooling towers, and other water treatment applications that demand accuracy, reliability, and full-featured automation.

The PC1500 includes ORP control for chlorine, bromine, or other oxidizers, pH control (acid or base feed), and temperature readout. It also calculates the Langelier Saturation Index using pH, temperature, alkalinity, and calcium hardness to help maintain optimal water balance. A safety flow switch ensures chemical feed is only active when water is flowing properly.

A large, easy-to-read LCD display with full-screen menus in English, French, or Spanish and support for U.S. or metric units ensures clarity for any operator. With automatic data logging, USB port for download, and remote communication capabilities via Ethernet or Wi-Fi, the PC1500 keeps operators connected and in control.
