This full-featured pH/ORP transmitter/controller is designed for drinking water, wastewater, and general-purpose applications. The analyzer offers a wide range of features: two adjustable high/low relays, one wash control, and two isolated 4 to 20 mA outputs (one for the selected measurement and one for temperature), and enhanced measurement stability with sample averaging functionality. Automatic calibration with preset standards for up to three buffers. Calibration data can be password protected with a programmable security code.
