[Demo unit available for loan] Suitable as a daily use tool for quality control.

★ Compact Rechargeable Pure Water Mist Generator "plus TRACER" This product creates ultra-fine, room-temperature dry mist using pure water (distilled water) to visualize the "airflow" and "differential pressure" conditions in factories and clean rooms. Its compact, lightweight, and cordless design allows for airflow visualization in various locations, effectively reaching hard-to-access areas such as narrow spaces and inside equipment. ★ D-Light Type-F The popular "D-Light" detection tool has undergone a full model change. It has achieved higher output, compactness, and lower power consumption. The detection capability and portability have been significantly enhanced. Since the contaminants themselves emit light, they can be clearly detected. Additionally, by observing the differences in light color, it is possible to estimate the type of contaminants. This is a new type of surface observation tool. ★ D-Light Type-P This tool is suitable for observing surface conditions, such as detecting scratches or particles on surfaces and checking surface irregularities. It can reduce the effects of glare caused by diffuse reflection on surfaces like metallic automotive paint, allowing for the visibility of foreign objects and other details that were difficult to observe with previous lights.

Detailed information

Visual tool for surface foreign object identification 'D-Light' Enables detection and classification of falling dust and adhering particles by visual inspection! Ideal for quality control in factories and daily hygiene management in hospitals and welfare facilities!
After D-light irradiation <Notebook PC keyboard> Turn off the room's fluorescent lights and direct the D-light towards the keyboard. Dust that was normally invisible, as well as dried liquid marks, can be clearly seen emitting fluorescence.
After D-light irradiation <Metallic surface> It is suitable for detecting foreign substances on metals. Since it emits green light, it is less likely to cause eye fatigue and is effective for long inspection periods.
Pure water mist generator "plus TRACER" Install the "plus TRACER" at the location where you want to check the airflow. It has a screw hole for a tripod, allowing for visualization of airflow in high places.
