Testo Stainless Steel Pitot Tube, 750mm

This Testo stainless steel Pitot tube is built tough for measuring flow velocity in ducts, especially where you've got high speeds or grubby air. It's an essential bit of kit for anyone dialling in combustion analysers or balancing commercial HVAC systems.

On a dusty Aussie rooftop job, you need gear that won't pack it in. This 750mm unit gives you the reach and durability to get reliable readings when it counts.

Best For

• HVAC technicians conducting air balancing and system commissioning
• Industrial maintenance teams performing combustion analysis
• Engineers verifying flow velocities in process air systems

Compatibility

This Pitot tube is designed to integrate seamlessly with Testo's range of combustion and emission analysers, including the popular Testo 340 and Testo 350 series. It connects via the included hoses to measure differential pressure, which the analyser then converts into flow velocity.

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, including dirty or high-temperature ducts.
• 750mm Length: Provides ample reach to position the probe accurately in the centre of larger ducts or stacks for representative velocity measurements.
• High Flow Velocity Measurement: Ideal for applications where air speeds are significant, ensuring accurate readings where other methods might struggle.
• Includes Hoses and Heat Protection: Comes complete with three 5-metre hoses for flexible connection to your analyser and a heat protection plate for safer handling in hot conditions.

Technical Specifications

What's in the Box

• 1 x Stainless steel Pitot tube, 750 mm length
• 3 x Connection hoses, 5 m long
• 1 x Heat protection plate

Using It on the Job

1. Connect to Analyser: Securely attach the three supplied hoses from the Pitot tube to the appropriate differential pressure ports on your compatible Testo combustion or emission analyser.
2. Probe Insertion: Carefully insert the Pitot tube into the duct, ensuring the measuring tip faces directly into the airflow for accurate velocity pressure readings.
3. Zero Check: Before measurement, always perform a zero-pressure check on your analyser to calibrate out any offsets, especially crucial for low differential pressures.
4. Maintain Position: Hold the Pitot tube steady during measurement to avoid fluctuations. Consider traversing the duct if a full velocity profile is needed.
5. Post-Use Care: After each job, gently clean the Pitot tube, especially the measuring tip, to prevent build-up from contaminated air streams. Store it in a protective case to prevent bending.

Limitations & Safety Notes

• This Pitot tube requires a compatible differential pressure measuring device (e.g., Testo 340/350 analyser or a manometer) to function and display readings.
• Not designed for use with highly corrosive gases without verifying material compatibility.
• Always ensure the probe is securely fitted and hoses are not kinked or leaking to maintain accurate pressure readings.
• Use the included heat protection plate and appropriate PPE when working in high-temperature environments.
• Follow Australian standards and Safe Work guidance for confined spaces or elevated work platforms if applicable to your measurement location.

Tradie Pro Tip

When you're trying to get a dead-accurate velocity reading in a tricky spot, try rotating the Pitot tube slightly back and forth. You'll see the differential pressure peak when it's perfectly aligned with the flow. Makes a huge difference for precise air balancing.

Pair With

Pair with a Testo 340 or Testo 350 combustion analyser and spare silicone connection hoses for comprehensive air and flue gas analysis, ensuring your systems are running efficiently and safely.
