55B053 - Walter pH Test Strips for Neutralization Verification (Pack of 5)

Precise Verification for Chemical Neutralization

The Walter 55B053 pH Indicator Strips are a critical quality control tool for industrial metal finishing and chemical cleaning processes. In the realm of stainless steel passivation and electrochemical cleaning, ensuring that the substrate has been returned to a neutral pH state is paramount. These indicator strips provide a reliable, immediate visual method for technicians to verify that all acidic residues from pickling pastes, electrochemical cleaning electrolytes, or other acidic treatments have been effectively neutralized and removed.

Failure to properly neutralize a surface after acid treatment can lead to "acid bloom," continued corrosion, or safety hazards for end-users. By utilizing these pH strips, operators can adhere to strict safety protocols and environmental standards. The strips are designed to react instantly to the presence of ions on the damp surface, changing color to correspond with a provided reference chart. This allows for a definitive go/no-go decision in the finishing workflow, ensuring that the workpiece is safe for handling and fully passivated.

Each package contains five booklets, providing an ample supply for busy workshops and production lines. They are particularly recommended for use in conjunction with Walter's Surfox system and neutralization fluids. Whether dealing with large tanks or localized weld cleaning, these strips are the industry standard for verifying that the chemical process is complete and the surface is chemically stable.

Technical Application and Compliance

These strips are an essential component of a compliant MRO strategy. They facilitate documentation of process control, allowing quality assurance teams to confirm that cleaning procedures meet specifications. The compact booklet design ensures that the strips remain protected until use and can be easily carried in a pocket or tool chest. For industries such as food and beverage, pharmaceutical, or architectural fabrication, where surface integrity is non-negotiable, the Walter 55B053 strips offer the peace of mind that the job is done right.
