Advanced Spectrometer and Flicker Meter for Visual Health

UPRTEK MK350S Premium

£3,098.00 excl. tax | £3,717.60 incl. tax

The UPRtek MK350S Premium spectrometer simplifies the evaluation of lighting based on key factors essential for safety, productivity, and visual health. Designed as a comprehensive handheld spectrometer, it helps optimize workspace lighting in accordance with current standards. This advanced tool empowers occupational health professionals, lighting designers, and facility managers to create environments that enhance visual well-being, fostering healthier and more productive spaces.
Indoor electric lighting often includes artefacts which are absent in natural daylight. When assessing or designing lighting for a working environment, several attributes are critical for productivity, visual health, and circadian balance. Adequate brightness levels (measured in lux) prevent eye strain and improve focus whereas insufficient or excessive lighting can cause glare or strain leading to discomfort or fatigue. Poor colour rendering and visual acuity can adversely impact wellbeing. Flicker has been associated with eye strain, headaches, migraines, and even seizures.
