Measuring only 3 x 2.3 x 0.75 in., Model UVX 300 can zero in on target as far as 350 mm away, safeguarding it from bumps. Sensor achieves feedback response time of 6 kHz, enabling high-speed sampling. Adjustable light projection and high resolution deliver pin-head sensitivity. Optional 50 mm lens will concentrate projected UV light into 5 mm spot. Numerical display shows intensity of each reading, easing fine tuning.
