Rosemount™ 372 Hydrofluoric Acid (HF) Resistant pH Sensor

The Rosemount 372 pH Sensor uses a glass formulation that slows down the attack from hydrofluoric acid (HF) considerably, making measurements in up to 1% (10,000 ppm) HF cost effective and economical. The hydrofluoric acid resistant pH sensor is designed for extended lifetime in processes containing fluoride ions. Measurement Range: 0 to 12 pH (0-14 pH if no sodium ions are present) Temperature Range: -5 to 50°C [23 to 122°F] (100°C [212°F] if no fluoride ions are present) Pressure Range: -13 to 135 psig (6.9 to 1035 kPa abs)
