Well-suited for wastewater neutralization, cyanide destruction and other pH-dependent processes, Systematics’ Model 960-3621 pH controller features plug-in output receptacles designed so that metering pumps or other devices can be easily and inexpensively connected for activation at programmable pH set points.
Simple routine calibration is said to be operator friendly, yet the instrument is packed with useful parameters such as ORP (mille volt display), temperature (manual or automatic), and high- and low-set-point adjustment. The wall-mounted enclosure is all plastic with an opening window for protection against corrosive metal finishing environments. A standard pH electrode is included, but a variety of special-purpose measurement electrodes also are available. Other options include 4–20-mA output, metering pumps and recorders.
