Analytical Measurements (Hopatcong, NJ) offers a new microprocessor based pH Indicator-Controller that, when connected to a Circular Chart, provides a complete monitoring and recording system for industrial wastewater. The controller is compact with user friendly programming. Additional features include:
- Two process controllers provided to activate alarms, pumps, etc., based on pre-set pH (or millivolt) set points.
- Either panel mounted with 1/8 DIN, or mounted in a NEMA 4X enclosure with hinged access panels.
- A probe and buffer solutions to calibrate the instrument.
If recording is needed, an optional Circular Chart Recorder can be included driven from the controllers’ 4-20 mA output. The recorder can be configured for either a 24-hour or 7-Day chart with 0-14 pH.
