pH Monitoring And Controllers
The Injecta Nexus Series pH monitoring and controllers are versatile devices designed for precise pH regulation in various applications, including water treatment, swimming pools, agriculture, and industrial processes. These controllers ensure optimal water quality by automatically adjusting pH levels through chemical dosing, making them ideal for maintaining system efficiency and compliance with regulatory standards. Whether used in hydroponics for nutrient balance, industrial plants for process control, or swimming pools for safe water conditions, the Nexus Series provides reliable and accurate monitoring. Its integration with high dosing pumps enhances automation and efficiency, making it a valuable solution for businesses requiring consistent pH management.

Nexus 3000 Series pH Monitoring and Controller
SINGLE PARAMETER READING
The instrument’s very large display allows all operating parameters to be viewed. The instrument can handle the following measurements: pH, Rx, Conductivity, Chlorine amperometric, mA input potentiostatic sensors , Flow
The following configurations are available:
– 144 x 144 mm Ip 65 for wall mounting
– 96 x 96 mm for panel mounting (with IP65 front and IP20 rear section)
It is possible to set the Relay2 output for the flushing function: through the Washing, Waiting for stabilisation and Interval of activation, the sensor cleaning process can be set to automatic mode.GUIDED CALIBRATION
The calibration wizard allows you to follow all the steps and return the quality of the sensors for optimal alignment.ON-OFF / TIMED / PROPORTIONAL RELAY ACTIVATION
The Relay output can be set in three different modes: On-Off activation, timed activation, proportional activation. These modes make it possible to find the right compromise in the management of chemical parameters within the process.ANALOGUE AND DIGITAL OUTPUT
The Nexus 3000, is equipped with 2 relays for set point control and probe cleaning management, temperature measurement and alarm control, a 4/20ma analogue output and a frequency output. The installer can set the instrument by choosing the most suitable configuration for the system.TEMPERATURE COMPENSATION
By using a temperature sensor, it is possible to display the temperature in the instrument’s display and make the compensation in the intended measurements.EVENTS AND ALARMS
Via the alarm list, it is possible to view the history of events recorded in the instrument. The entire list can be reset at any time.
