WHICH LIQUID PENETRANT TESTING METHODS DO YOU APPLY? We use two different methods involving either a colour-contrasting liquid or one that glows up under UV-light. Mostly the penetrant washes off with just water, yet we sometimes also apply a chemical solution. Both options are offered for you to choose.
IS LIQUID PENETRANT TESTING POSSIBLE UNDER COLD CIRCUMSTANCE? Yes, because we then switch over to another method, which is suitable to use in circumstances way beyond freezing point.
CAN LIQUID PENETRANT TESTING BE USED FOR FOOD PRODUCTION? Yes it can, we apply another method and liquid, thus guaranteeing food safety requirements.
IS LIQUID PENETRANT TESTING POSSIBLE ON HOT SURFACES? It is possible to a certain degree. Please let us know which temperature you are referring to, then we can determine which method is suitable.
