APPARATUSES AND METHODS FOR MEASURING UV ABSORPTION RATE

摘要

The present invention proposes an apparatus and method for measuring the UV absorption rate of a liquid (130) in a container (120) comprising a UV lamp (110), using two sensors (141, 142) to measure intensities of two associated beams of light originating from the UV lamp (110) and passing through the liquid (130), and determining the UV absorption rate based on these two light intensities and at least one transmission distance of the two beams of light. One of the two associated beams of light is a beam of UV light, the other is a beam of UV light or visible light or near IR light.
