Pitot Tube, 13.8 inch Stainless Steel

This 13.8 inch (350 mm) stainless steel Pitot tube is your go-to for accurate air velocity measurements, especially in challenging environments like dusty return air ducts or industrial extraction systems.

It's built tough to handle high flow velocities and heavily contaminated airflow, so you're not constantly cleaning it out on the job.

Best For

• HVAC technicians balancing air systems
• Industrial maintenance teams checking extraction rates
• Process engineers monitoring airflow in industrial applications
• Anyone needing reliable airflow data in ducted systems

Compatibility

This Pitot tube is designed to integrate with compatible differential pressure measurement devices. You'll need a connection hose (like Testo's silicone or silicone-free options) and a precision pressure probe to complete your setup. It's a standard design, but if you're running a different model, check fittings and specs before ordering.

Features

• Robust Stainless Steel Construction: Built to last in demanding industrial and commercial HVAC environments.
• 13.8 inch (350 mm) Length: Ideal for accessing various duct sizes and reaching central flow points.
• Handles High Flow Velocities: Provides accurate readings even in fast-moving air streams up to 100 m/s.
• Designed for Contaminated Air: Less prone to clogging and blockage when working in dusty or particle-laden airflow.
• Wide Operating Temperature Range: Suitable for applications from 0°C up to +600°C.

What's in the Box

• 1 x Stainless Steel Pitot Tube, Ø 7 mm, length 350 mm

Using It on the Job

1. Connect the Pitot tube to your differential pressure gauge using a suitable connection hose.
2. Ensure all connections are secure and leak-free for accurate readings.
3. Insert the Pitot tube into the duct, aligning the tip against the airflow for total pressure measurement, and the static port perpendicular to the flow.
4. Take multiple readings across the duct cross-section and average them for a representative velocity, especially in larger or irregular ducts.
5. After use, carefully withdraw the Pitot tube and wipe down the exterior to remove any debris or contaminants, particularly if used in dirty environments.

Limitations & Safety Notes

• Requires a separate connection hose and differential pressure probe/meter for operation.
• Not suitable for use in highly corrosive or explosive atmospheres unless specifically rated for such conditions.
• Always ensure proper insertion into ducts to prevent damage to the tube or injury from moving parts within ventilation systems.
• Follow manufacturer's guidelines for compatible instruments, storage, and cleaning practices.

When you're trying to get a good average velocity in a duct, don't just take one reading. Map out a few points across the cross-section, especially in larger or rectangular ducts, to get a more reliable flow calculation. It makes a real difference.
