Connection hose, silicone, 5m long - max load 700hPa (mbar)
Pressure connection hose, single, Ø:4/6 mm, 50 cm, long, without connection adaptor
Pressure set with flue draught probe, includes 2 silicone hoses, each with Ø 4 mm and 6 mmmm, 4mm and 6 mm T-piece, connection part
Pitot tube, 350 mm long, stainless steel, measures velocity, speed

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.

testo Electronic Manifolds

The testo 550 series electronic manifolds with up to a 3-way valve bank are the ideal tools for regulating refrigerating systems. They are high quantity sensors for measuring pressure, vacuum and temperature.

Display condensation and vaporisation temperatures - the measured pressure on the suction and pressure side is shown on the display. The calculation and display of the respective condensation and evaporation temperatures for the selected refrigerant take place at the same time
Valve bank for temporary alteration to flow passages
