FAQ

What is ABB 100E used for?

ABB 100E is a compact 12 mm pH/ORP sensor designed for general-purpose water measurement applications such as drinking water, environmental monitoring, irrigation, and aquaculture.

What is the difference between ABB 100E and 100 GP?

The main difference is the application focus:

• 
  100E: Basic and economical pH/ORP measurement for clean water and general applications.
  
• 
  100 GP: More advanced industrial sensor designed for water, wastewater, and cooling water applications with enhanced reference protection and fouling resistance.
  

Does ABB 100E require electrolyte maintenance?

No. The 100E uses a gel electrolyte reference system, which reduces maintenance compared with refillable electrolyte sensors.

Can ABB 100E measure ORP?

Yes. With the platinum ORP electrode configuration, the sensor can measure redox potential from -2000 to +2000 mV.

What is the recommended conductivity range for ABB 100E?

The ABB 100E is recommended for samples with conductivity of approximately 100 μS/cm or higher. For lower conductivity or ultra-pure water applications, ABB 100 ULTRA or 700 ULTRA series sensors are more suitable.
