The Van London Co. (aka Van London pHoenix Co.) Mark X Pneumatic Retractable pH / ORP Sensor Assembly permits continuous pH or ORP monitoring where service must be performed without process interruption. It can be mounted vertically or inclined in reactors of pilot and production plant facilities.

 Mark X Assembly
  • Low Cost Electrode Replacement
    An all-in-one electrode design incorporates the measuring, reference, and optional automatic temperature compensator (ATC) in one reducing inventory requirements.
     
  • O-ring and Ball Valve Arrangement
    Prevents process spray or process contamination of junction box or conduit, even in the event of electrode breakage.
     
  • Automatic Cleaning Capabilities
    Use of select microprocessor-based analyzers or a DCS will enable the assembly for automatic cleaning or calibration.
     
  • Quality "Built In"
    All Van London Co. (aka Van London pHoenix Co.) assemblies and electrodes meet strict, documented quality control specifications, followed through each step of the manufacturing process.
  Mark X Pneumatic Retractable Sensor Assembly for pH AND ORP
 
DESCRIPTION
The Van London Co. (aka Van London pHoenix Co.) Mark X Pneumatic Retractable Sensor Assembly permits continuous pH or ORP monitoring where service must be performed without process interruption. It can be mounted vertically or inclined in reactors of pilot and production plant facilities. The replaceable electrode cartridge is sold separately and selected depending upon the application requirements. For maintenance, removal, or cleaning, the sealed electrode is withdrawn from the process during operation and into a separate locking chamber. O-ring placement within the assembly prevents process leakage even after repeated retraction. For electrode cartridge removal or sensor assembly over-haul, a ball valve is supplied for process isolation and additional safety.
