How It Works
Detailed instructions are available in our PosiTest AIR Instruction Manual
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.
1. Apply the PosiTest AIR Test Solution
2. Place clear Test Chamber over the test area
3. Initiate the test (depressurize the chamber)
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 Desktop Software. Test results include rate of depressurization, pressure differential limit, time duration and user-entered PASS/FAIL conclusion.
Does the PosiTest AIR include a certificate of calibration?
The PosiTest AIR arrives fully calibrated and ready to measure. A long-form Certificate of Calibration showing traceability to a national standard is included at no additional expense. For organizations with re-certification requirements, the PosiTest AIR may be returned at regular intervals for calibration. DeFelsko recommends that our customers establish their instrument calibration intervals based upon their own experience and work environment. Based on our product knowledge, data and customer feedback, a one year calibration interval from either the date of calibration, date of purchase, or date of receipt is a typical starting point.
Can dish soap be used instead of the included solution?
DeFelsko recommends the use of PosiTest AIR Test Solution only. Dish soap and other common soapy liquids don't have the necessary viscosity and formulation to reliably create visible bubbles when encountering the types of air leaks that the instrument is designed to detect. Using such non-specific liquids may result in building envelope air leaks being missed. They also don't comply with the ASTM E1186 standard as they will form bubbles when applied to the are being measured.
Extensive research and development went into the formulation of our PosiTest AIR Solution. This proprietary high viscosity formulation ensures...
Air bubbles properly form and are visible when an air leak is present – leaks don't get missed!
air bubbles don't form when solution is applied to test area (in compliance with ASTM E1186)
optimal results when measuring on vertical surfaces – test solution doesn't flow away from the test area
proper test solution performance in cold environments down to -10° C/14° F (low temperature solutions available for measuring down to -20° C/-4° F
PosiTest AIR Test Solution
Every PosiTest AIR comes complete with (4) bottles of Test Solution. Additional bottles are available in cases of (16) 8 oz. bottles.
Each bottle includes application dauber
Operating temperature: 14° to 149° F (-10° to 65° C)
The PosiTest Air Test Solution has been specially formulated not to have any adverse effects on waterproofing, roofing, air barrier membranes or the PosiTest AIR tester. Do not use on spun polyolefin building wrap.
