Дымный карандаш
A pocket-size smoke pencil producing a narrow, low-velocity tracer stream for quick qualitative checks of drafts, leakage paths and localized airflow.
- Pencil-thin low-velocity tracer.
- Reusable capped metal holder.
- Precise localized airflow checks.
Введение продукции
The reusable pen-style holder accepts a replaceable smoke wick and protects the remaining insert under a close-fitting extinguishing cap. Its pencil-thin plume is suited to door gaps, fume hood faces, grilles and small enclosure openings where broad fog output would mask the exact flow direction. The slim anodized body and pocket clip keep the tool accessible during inspection rounds.
Основные характеристики
Low initial plume velocity limits disturbance of the observed path.
Replaceable wick inserts allow repeated short checks.
Protective cap extinguishes and stores the remaining insert.
Slim metal holder is easy to position beside gaps and grilles.
Pocket clip and compact case support field inspection work.
Обеспокоенность клиентов продуктами
Small drafts and leakage paths require a tracer source that can be placed close to the opening without flooding the area or pushing the air being observed.
A large fog source can hide the direction of a very small draft.The exposed wick produces a thin tracer line close to the test point.
Tracer discharge momentum can influence weak local airflow.The smoke rises from the wick with minimal initial projection.
Single-use smoke sources create unnecessary waste during short checks.The cap extinguishes the insert so the unused portion can be retained for later tests.
Small inspection tools are easily misplaced between rooms.A metal pocket clip and compact protective case keep the holder and spare inserts together.
