A portable cleanroom door leakage tester for applying a controlled pressure difference to a defined door-seal test boundary while recording differential pressure, airflow and calculated leak rate.
- Controlled differential-pressure testing.
- Synchronized airflow and leak-rate display.
- Portable localized door-seal interface.
مقدمة المنتج
This field system combines regulated airflow, dual-channel pressure referencing and a foldable local seal interface in one portable kit. The rectangular hood or narrow-gap attachment is temporarily sealed over a defined section of the closed door perimeter, while two color-coded pressure tubes reference opposite sides of the test boundary. The operator adjusts the single airflow path until the specified differential pressure is stable, then records the flow required to maintain that condition and, where applicable, normalizes the result by the entered test length or area. The instrument supports comparative commissioning and troubleshooting measurements; it does not automatically certify an entire cleanroom door, adjacent wall or room envelope. Test pressure, boundary preparation, allowable leakage, environmental state and result interpretation remain controlled by the approved method.
الخصائص الرئيسية
Six-key local interface supports target entry, zeroing, stabilization timing, data capture and result recall with a fixed physical control layout.
One fine pressure-adjustment knob and one visible flowmeter provide direct feedback while the selected pressure condition is established.
Red and blue pressure tubes keep the two pressure-reference sides identifiable from the instrument ports to their endpoint probes.
One flexible main hose connects the airflow source to a foldable rectangular seal hood for localized door-edge or gasket testing without depicting a full test chamber.
Rugged blue-gray enclosure, top carry handle and four stable feet support temporary cleanroom commissioning and maintenance work.
مخاوف المنتج للعملاء
Door leakage measurements are sensitive to the temporary test boundary, pressure-reference position, HVAC stability, tested perimeter length and flowmeter range; controlling these variables is essential before two results can be compared.
Air escaping through the temporary hood seal can be mistaken for leakage through the door gasket.Clean the contact surface, use the correct seal-frame size, secure the perimeter uniformly and perform the defined blank or attachment-leak check before measuring the door segment.
Normal HVAC pressure fluctuation can prevent a stable differential-pressure reading.Test in the specified room state, allow the pressure cascade to settle, route both reference tubes away from drafts and use an agreed stabilization window before logging flow.
A test may be recorded before the target pressure is reached or while the regulator is still changing.Approach the target gradually with the single adjustment knob, verify the pressure and flow trend together, and capture data only after both values meet the stability rule.
Leak rates from different doors can be compared even though the tested length or area is different.Record the exact hood boundary and exposed seal length, apply the same normalization basis and compare only results obtained at the same specified pressure difference.
A localized door-edge result can be interpreted as proof of whole-room airtightness.Identify the tested segment in the record and combine local findings with the separate room-envelope or door-assembly method required by the approved test plan.
Very low or high leakage can fall outside the installed flowmeter range.Select the appropriate flow range or calibrated nozzle option, verify zero and tubing connections, and repeat the test within the instrument's usable operating window.
