AWISEL Smoke Pen

Clean observation in testing

Traceable airflow, made visible.

The Smoke Pen works like a traditional snap pen. A smoke emitter wick is placed inside the pen, adjusted to protrude about 10 mm, then lit with a lighter or match. The protective cover extinguishes the wick and stores the remaining material for the next use.

Smoke not classified as toxic
According to the SDS, the product is not classified as hazardous or toxic and supports clean, controlled observation under normal conditions of use. (View MSDS)
Continuous trailA visible, traceable white smoke trail that makes airflow direction easier to observe and record.
No initial velocityThe smoke source creates less disruption at the release point, which supports cleaner airflow observation.
Cool-burning sourceThe cool-burning smoke source is highly useful for clean observation of airflow, recovery measurements and smoke detector checks.

Airflow visualization

Invisible behavior becomes visible evidence.

Airflow visualization tests are a very important part of testing, inspection and certification of HVAC systems. The Smoke Pen produces a traceable continuous smoke trail that has no initial velocity. This makes it possible to observe airflow performance without disruptive effects from the smoke source. These tests provide an observable indicator of airflow performance. This information is required to document the level of success of the tested environment. Tested environments may have technical requirements according to national and international regulations and guidance such as cGMP, EU GMP, ISO 14644, ASHRAE 170, DIN 1946-4, NSF/ANSI 49, EN 12469, ASHRAE 110 and EN 14175.

The Smoke Pen has been used for airflow visualization in cleanrooms, pharmaceutical manufacturing areas, operating rooms, intensive care units, isolation rooms, laboratories, biosafety cabinets, fume hoods, laminar flow units and air duct systems.

Smoke detector test with Smoke Pen

Life-safety requirements

An easy and safe smoke source for detector checks.

Smoke detectors can be easily tested by using the Smoke Pen. The most critical part when testing smoke detectors is that the test media should be as similar to fire smoke as possible. It should have a long hang time, which is especially important when testing air sampling systems. The test media should not harm the detector's function.

Manufacturer (Björnax AB) has performed a test where they used the Smoke Pen and tested more than one smoke detector 200 times each, with the test time measured from smoke exposure to triggered alarm. The summary is that there was no extra delay in response time after all tests, or any other malfunction noted.

Recovery measurement

Particle generation source for ISO 14644-3 recovery testing.

The Smoke Pen is a particle generation source for cleanroom recovery testing according to ISO 14644-3. Ninety-six percent of the smoke particles are between 0.1 μm and 1.0 μm; the remaining particles are larger. In a cleanroom with 20 air changes per hour, releasing a smoke trail from the Smoke Pen for 3 seconds is sufficient. After the smoke has been distributed uniformly throughout the cleanroom, recovery time can be measured with any Light Scattering Airborne Particle Counter (LSAPC). This test is used to determine the cleanroom's ability to remove airborne particles and return to the specified cleanliness class after a particle generation event. Recovery of the specified cleanliness class after contamination is one of the most important capabilities of a cleanroom.

96%of smoke particles are between 0.1 μm and 1.0 μm; the remainder are larger.
3 secof smoke trail release is sufficient in a cleanroom with 20 air changes per hour.
