Twist-Lock ph & ORP

Twist-Lock 1 Twist-Lock 2
Low Cost Replacements
Long-lasting, reliable, and low in cost for pH and ORP sensors. Twist-Lock housing design allows for an all-in-one electrode or sensor replacement to reduce inventory requirements.

Housing Features
¼ turn is all that is required for installation. The housing is ribbed for easy handling.
O-ring Arrangement
Dual external o-rings and an internal o-ring seal the electrode from any process leakage.
Quality "Built In"
All parts meet strict, documented quality specifications, followed through each step of the manufacturing process.

Safe Operation
A stop pin is installed in the adapters for positive electrode/sensor positioning; locking pins on the housing are visible through an opening 90° from the removal slots to assure correct installation.
The Van London-pHoenix Co. Twist-Lock™ mounting system provides continuous pH, ORP, or Conductivity monitoring with safe and convenient service capability for any flow-through system. Typical installations include by-pass streams, sample systems, or sensor stations.

Dimensional and Mounting Detail
Installed Twist-Lock Series Twist-Lock Installation Angle Range
Adapters, tees, electrodes and sensors are all sold separately. A Twist-Lock adapter is required for initial installation.
To build your own part number, first determine the electrode or sensor style required and then replace X's, Z's, and Q's with selections listed in the drop-down menus on the back page.
Call the factory if electrode application assisstance is required. Conversion information is also available for quick replacement of existing installations.
