This pitot tube from Testo allows for the accurate measurement of air or liquid pressure in pipes, ducts or weirs. The tube is made from high-quality stainless steel, which offers excellent chemical and corrosion resistance. As this metal is durable and long-lasting, the tube is ideal for measuring high-flow velocities or heavily contaminated atmospheres. This component is compatible with Testo 512 manometers, which simultaneously offer pressure and flow measurements in one compact instrument.

• Extremely wide operating temperature range of 0°C to +600°C for use in harsh environments
• Broad measuring range of +1 to +100m/s for versatility
• Slender probe that can be inserted into an existing pressurised pipeline for improved ease of use
• Low loss of pressure when inserted for a high level of measuring accuracy

• Refrigeration and cold storage
• Filter measurement
• Tightness and leak detection

A pitot tube works according to a basic principle of fluid mechanics: if a fluid stops flowing, its kinetic energy is converted into pressure energy. The tube works by assisting in measuring the pressure energy of stopped fluid at any point in a pipe or channel.
