The 400 ml Ambro-Sol W501 spray tank is a professional red penetrating, ideal for identifying cracks, porosity and surface defects on welds, prints and metal parts. This product is designed for non-destructive control applications (CND) in industrial, automotive and craft industries. Its low-voltage surface formulation ensures deep penetration in microfessures, making even the smallest defects visible when used in combination with a white detector. The result is a precise and reliable control, essential to ensure the safety and quality of metal processing. Mode of use: shake the tank well before use. Spray evenly on the clean and dry surface to inspect. Allow to act for a few minutes, then remove excess with absorbent paper or compressed air. Apply the white detector (available separately) to highlight any cracks or defects. Repeat the process if necessary. The tank is made of recyclable tinplate and produced in Italy, guaranteeing high quality and safety standards for the user.
