Testo 3.3 ft Stainless Steel Pitot Tube

This Testo 3.3 ft (1000 mm) stainless steel pitot tube is purpose-built for accurate airflow velocity measurement in demanding HVAC and industrial environments. It's a solid bit of kit for any tech or engineer needing reliable data on duct systems.

When you're dealing with dusty rooftop units or contaminated exhaust stacks here in Australia, you need a probe that can take a beating and still give a true reading. This pitot tube is up to the task.

Best For

• HVAC service and installation technicians
• Industrial process engineers
• Building commissioning specialists
• Maintenance teams measuring duct airflow

Compatibility

This pitot tube is designed to integrate with compatible differential pressure measurement devices, requiring a connection hose and a suitable pressure probe for full functionality. It's ideal for use with Testo's range of handheld meters and combustion analysers that support differential pressure inputs.

If you're running a different model, check fittings and specs before ordering.

Features

• Robust Stainless Steel Construction: Built to withstand harsh industrial and commercial environments, ensuring long-term durability.
• 1000 mm Length: Provides ample reach for accurate measurements in larger ducts and exhaust systems.
• Designed for High Flow Velocity: Delivers precise readings even in rapid airflow applications where other methods might struggle.
• Handles Contaminated Flow: Its design allows for effective measurement in heavily particulate-laden air streams without clogging.
• 7 mm Shaft Diameter: Slim profile allows for easier insertion into test ports with minimal impact on airflow.

What's in the Box

• 1 x Stainless Steel Pitot Tube, Ø 7 mm, 1000 mm length

Using It on the Job

1. Prepare Equipment: Ensure your differential pressure gauge is calibrated and ready. Connect the pitot tube to your gauge via appropriate connection hoses.
2. Identify Test Point: Select a suitable measurement point in the duct, ideally a straight section with minimal turbulence. Drill or use an existing access port large enough for the 7 mm probe.
3. Insert Pitot Tube: Carefully insert the pitot tube into the duct, ensuring the tip faces directly into the airflow. Position it at the centre or other specified points for an accurate traverse.
4. Take Readings: Record the differential pressure reading from your connected gauge. Use appropriate calculations or your gauge's internal functions to convert this to airflow velocity.
5. Remove & Store: Once measurements are complete, carefully remove the pitot tube. Wipe it clean, especially if used in contaminated environments, and store it safely to prevent damage.

Limitations & Safety Notes

• Always ensure the pitot tube is correctly connected to the differential pressure instrument before insertion.
• Do not use the probe in explosive atmospheres unless explicitly rated for such conditions.
• Be aware of high temperatures within ducts; always use appropriate PPE.
• This pitot tube is a measuring accessory and requires a separate pressure probe and connection hoses for full functionality.
• Follow all Australian workplace safety standards and manufacturer guidelines during use.

Tradie Pro Tip

To get reliable readings in dirty ducts, always double-check that the pitot tube's measuring ports are clear before and after use. A blocked port will give you bogus numbers, wasting your time and potentially leading to incorrect system adjustments.

Pair With
