372 Hydrofluoric Acid (HF) Resistant pH Sensor

Brand: Rosemount
Request Information
The Rosemount 372 sensor uses a glass formulation that slows down the attack from HF considerably, making measurements in up to 1% (10,000 ppm) HF cost effective and economical.
Features
  • Enhanced resistance to process attack provided by field-proven pH glass formulation
  • Extended sensor life provided by double junction reference cell for process solutions that contain poisoning ions
  • Versatile mounting options provided by 3/4" Male NPT forward facing and 1" Male NPT reverse facing threads
  • Superior chemical resistance due to rugged Ultem body, completely sealed to eliminate sensor leakage
