HOW IT WORKS

The portable, hand-operated PosiTest AIR Leak Tester tests the air barrier integrity of single, two-ply and liquid membrane systems, including air barriers, roofing systems, waterproofing and ground liners by locating leaks.

In accordance with ASTM E1186, the PosiTest AIR will indicate whether leaks exist in the test area. It is a simple Pass/Fail test.

Quick Overview – Performing a Test

1. Apply the PosiTest AIR Test Solution to the test area

2. Place the clear Test Chamber over the test area

3. Initiate the test (depressurize the chamber)

The location of an air leak is indicated by bubbling of the Test Solution. An estimate of the relative size of the leak can be made based on the size and speed with which the bubbles form. The image below demonstrates an air leak is present: (FAIL test result). Upon completion of the test, the maximum pressure differential and duration of the test will flash on the display.

4. Store Test Result (optional)

The PosiTest AIR’s internal memory can store up to 200 test results which can be transferred to a PC using PosiSoft 3.0 Desktop Software. Test results include rate of depressurization, pressure differential limit, time duration and user-entered PASS/FAIL conclusion.
