FF20 Flow Fittings for pH/ORP Measuring Loops

Brand: Yokogawa Electric Corporation

For liquid analysis, the sensors are usually mounted in either a flow or an immersion fitting. 

Therefore Yokogawa has invested considerable design and development time in producing a full range of fittings with particular emphasis on designs that reduce installation and maintenance time and consequently save operation costs.

A high degree of standardization makes it possible to mount electrodes with DIN dimensions directly into a fitting. 

For most other types a mounting kit (accessory) is available. A wide choice of construction materials gives the user the optimal solution for any process considering chemical resistance, pressure and temperature specifications.
 
The program includes fittings and subassemblies for mounting of a variety of electrodes and/or a cleaning system.
Features
  • Wide choice of construction materials.
  • High degree of standardization reduces spare holding requirements.
  • Direct mounting of sensors with DIN dimensions.
  • Liquid earth pin for stable measurements.
  • High pressure and temperature specifications.
  • Chemical cleaning system as an option for 2-, 3- and 4-hole fitting.
  • Brush cleaning system as an option for 4-hole fitting only.
  • Electrolytically polished stainless steel fittings for optimal corrosion resistance.
