Micromomanómetro
A high-resolution dual-port micromanometer for cleanroom pressure-cascade checks, filter pressure-drop testing and Pitot-tube duct traverses.
- High-resolution low-pressure measurement.
- Dual ports for cleanroom cascade verification.
- Pitot velocity and volume-flow calculation.
Introducción del producto
This portable micromanometer resolves small static and differential air pressures through two color-coded pressure ports. Automatic zeroing, selectable engineering units and damping help stabilize readings at airlocks and controlled rooms. With a Pitot tube and entered duct geometry, the same instrument can calculate velocity and air volume during ventilation commissioning.
Características clave
Dual ports support positive, negative and differential measurements.
Selectable damping steadies readings affected by door movement or turbulence.
Pitot input converts velocity pressure into duct air speed and flow.
Min, max and average capture supports systematic test-point review.
Rugged handheld enclosure suits qualification and maintenance routes.
Preocupaciones del producto del cliente
Controlled environments depend on small pressure differences that must be measured without confusing transient fluctuations, tubing polarity or instrument drift.
Small room-pressure differentials can be obscured by sensor noise.A high-resolution low-pressure sensor with damping produces a stable displayed value.
Reversed tubing can make pressure direction difficult to interpret.Color-coded positive and negative ports make the connection polarity immediately visible.
Door movement creates short transients during cascade checks.Averaging and min/max capture distinguish the settled relationship from brief disturbances.
Duct velocity calculations add time and opportunities for arithmetic errors.Pitot mode and entered duct dimensions provide direct velocity and volume-flow results.
