Product Introduction

This field kit brings together the instruments and connections needed for duct pressure traverses. The digital micromanometer measures velocity pressure, calculates air speed and converts entered duct dimensions into volume flow. A graduated stainless Pitot-static probe, paired hoses, magnetic support and fitted case keep the test arrangement consistent between commissioning locations.

Key Features

Matched meter and Pitot probe support immediate duct traverse work.

Color-coded tubing preserves total and static pressure polarity.

Entered round or rectangular duct dimensions enable direct flow calculation.

Point storage and averaging organize multi-location traverse results.

Graduated stainless probe supports repeatable insertion depth.

Fitted hard case protects the complete set between test locations.

Customer Product Concerns

A reliable duct traverse depends on compatible instruments, correct pressure polarity and complete accessories arriving together at every test location.

Missing adapters or tubing can halt a scheduled duct test.The fitted case keeps the meter, Pitot probe, paired hoses and mounting accessories together.

Pressure polarity is easy to reverse during repeated traverse points.Blue and red connections consistently identify static and total pressure paths.

Manual conversion from velocity pressure to airflow is time-consuming.The meter calculates velocity and volume flow from pressure and entered duct geometry.

Unstructured point records make average duct flow difficult to audit.Point storage and averaging retain the traverse sequence and calculated mean.

Typical Applications

Cleanroom supply and exhaust duct traversesHVAC testing, adjusting and balancingAir-handler performance verificationVentilation commissioningFilter and coil pressure-drop diagnostics
