Case Study #11
High HF Resistant pH Sensors for
HF neutralization

Reduce sensor replacement with the most high HF resistant pH sensors available on the market with novel pH glass formulation and solid-state non-porous reference system.

• Improved HF treatment system efficiency through more accurate pH measurement and control
• Reduced Sensor Usage through less breakage during cleaning
• Reduced maintenance and increased service time from sensors using solid state polymer reference system & specialized high HF resistant pH glass
