372 HF resistant pH Sensor

372 HF resistant pH Sensor
Manufacturer:
Emerson

372 model pH sensor manufactured by Rosemount Analytical uses a spacial glass that has higher resistance to hydrofluoric acid (HF) and dissolved fluorine that ordinary sensors. This model is recommend for application in water containing dissolved fluorine or hydrofluoric acid for measurement of pH level of etching solution.
