The Deltaflow-pitot by Systec Controls is the perfect sampling instrument for performing coherent measurement as indicated by DIN 2640 standards. It has the same and precise profile in deltaflow Df25 which is used to check and align existing measurements. Also, it comes with a testing profile which features great degree of impenetrability to contamination and building up of moisture. The deltaflow pitot is the ideal tool for plants and in the heating and cooling industry to test the effectiveness of the ventilators, air admission and exhaust. Since the deltaflow pitot might be dismantled upon transport, it could be agreeably transported in a convey case. Due to its straight structure design, it can be effectively embedded into the inspecting cross-section using its previously existing gaps.
