8202 pH or ORP Meter

Brand: Burkert Fluid Control Systems

The Type 8202 is a compact measuring device designed for the measurement of:
  • The pH in clean liquids or liquids containing solids, sulphides or proteins
  • The oxidation-reduction potential (ORP) in clean liquids or liquids containing solids, sulphides or proteins which may present low conductivity
The meter consists of a replaceable 120 mm standard PG13.5 pH or ORP probe Type 8203 with S8 Connector, screwed in a probe holder with integrated Pt1000 temperature sensor. 

This ensemble is plugged-in and screwed with a nut to an enclosure with cover containing the electronic module and a removable display. Thus the Burkert meter facilitates short installation and maintenance effort.
Features
  • Integral compact measurement device for direct connection to control level (PLC)
  • Usage of 120 mm standard PG13.5 pH/ORP-probes with S8 connector 
  • Simulation of process value and diagnostic function
