Penetrant Processing Inspection Equipment

ZA-37 is a high-performance, integrated processing/inspection system for fast and reliable manual penetrant testing. It comes in three models, each designed for a specific testing method. Its modular design varies with different penetrant materials.

  • ZA-37W – Water-Washable Method – These are the simplest units because water can be used directly to wash excess penetrant from parts without additional steps.
  • ZA-37E – Post-Emulsified Method – These units can locate extremely shallow flaws, but they require an extra processing step – applying an emulsifier – to make the penetrant washable.
  • ZA-37H – Hydrophilic Method – These units deliver the highest sensitivity, but require an additional processing station for pre-rinsing parts.
