pH Controller & Alarm Supports both high/low pH control, 103dB buzzer, 3-color stack LED light

Gizmo Engineering PH-1 is a rugged industrial pH controller and alarm system designed for precise monitoring and automated control of pH levels in demanding environments such as wastewater treatment, chemical processing, and plating operations. Built with durability and reliability in mind, the PH-1 combines measurement, alerting, and dosing control into a single, compact unit. At its core, the PH-1 continuously monitors pH levels and allows users to define separate setpoints for both control and alarm functions. This enables automated activation of chemical dosing pumps to maintain desired pH ranges, while also triggering alerts if levels move outside acceptable thresholds. The system supports both high and low pH control, making it suitable for a wide range of industrial processes. A standout feature of the PH-1 is its multi-layered alert system. It includes a high-volume 103 dB audible buzzer and a three-color stack light that visually communicates system status-green for normal operation, red for out-of-range conditions, and yellow when pumps are active. This ensures operators can quickly identify issues, even in noisy industrial settings. The unit is housed in a compact, wall-mountable ABS enclosure with an IP65 rating, making it resistant to water, dust, and corrosive environments. Its plug-and-play design and eXternal control buttons allow for easy setup, calibration, and manual pump operation when needed. For integration into larger systems, the PH-1 offers RS485 and 4-20 mA outputs, enabling data logging and communication with plant monitoring or SCADA systems. Optional features include a data logger, dry contact relays, and BNC probe connections for fleXible deployment. Overall, the Gizmo Engineering PH-1 is a robust, user-friendly solution for maintaining pH stability, improving process control, and ensuring regulatory compliance in industrial applications.
