HF Scientific - Environmental Testing Equipment - AdvantEDGE pH Electrode Sensor

pH Electrode Sensor

This pH sensor head is part of the AdvantEDGE probe system that allows a direct connection to a PLC for seamless integration with industrial control systems. Use any computer to display data, calibrate and customize the measurement without an intermediate analyzer electronics box. A LD500 local display can be used if desired. Sensor heads are pre-calibrated and can be replaced or exchanged with any other type of sensor without taking the system down. Save space, time and money.
