The BSC PREFERRED BOS98343 is a 395nm ultraviolet penlight designed for hands-on inspection work across automotive, industrial, and service trade applications. The UV LED emits at 395 nanometers, a wavelength effective for revealing fluorescent leak dyes, pet urine, biological stains, and other materials that are invisible under standard white light. The body is machined from lightweight aluminum and includes a belt clip for easy carry during service calls. Two AAA batteries are included and provide up to 6 hours of continuous runtime before replacement.
This penlight is suited for HVAC technicians tracing refrigerant leaks with fluorescent dye, automotive mechanics inspecting fluid systems, and other tradespeople who need a compact UV source for field inspections. The compact form factor fits standard tool pouches and shirt pockets, making it a practical addition to any inspection kit. Industrial tradesmen and service techs will find the 6-hour battery life sufficient for a full shift of intermittent use.
Designed as a general-purpose UV inspection penlight suitable for automotive, HVAC, plumbing, and industrial service applications requiring a 395nm ultraviolet light source.
No installation is required for this handheld inspection tool. Insert two AAA batteries observing correct polarity before first use. When using UV light for leak detection, power down equipment where safe before inspecting fluid or refrigerant systems. Avoid directing UV light directly at eyes.
