Which pH glass should I choose for my chemical application?

Choosing the right pH glass is critical for measurement accuracy, sensor lifetime, and reliable performance. The optimal pH glass depends on your process conditions and application requirements.

• PHI Glass 
  Offers the longest lifetime in applications with frequent hot cleaning cycles with NaOH, sterilization, and autoclave cycles while maintaining very low drift. It also provides good accuracy at high pH values and elevated temperatures.
• HB Glass
  Provides a long lifetime in applications with frequent hot sterilization and autoclave cycles and delivers the fastest response time.
• HF Glass 
  Specifically designed for use in media containing hydrofluoric acid (HF), offering superior robustness and reliability in these demanding environments.
• H Glass 
  Delivers stable measurements in anhydrous or partially aqueous solutions. It offers the lowest alkali error and works well in most chemical applications.
