Industrial The Twist-Lock sensor and adapter is designed to convert a standard pipe tee into a low cost, low maintenance flow-through sensor assembly. Only a ¼ turn is required for field maintenance or sensor replacement; threading is eliminated. The adapter is available in a variety of materials & connection sizes for easy installation. The Van London Co. Twist-Lock mounting system provides continuous pH, ORP, or Conductivity monitoring with safe and convenient service capability for any flow-through system.
