Fluorometer chlorophyll

WebAug 3, 2013 · As chlorophyll fluorescence is a measure of re-emitted light (in the red wavebands) from PSII, naturally this means that any ambient light can interfere with the measurement of fluorescence and thus many early systems had to be used in darkness and/or highly controlled light environments. WebFluorometers or fluorospectrometers are used to identify the presence and quantity of specific molecules in a medium. The mechanisms of measurement involve a light source …

Webfluorescence of chlorophyll a can even be measured from aircraft or satellites [3,4]. However, aerial methods can only measure chlorophyll a at the ocean surface during daylight hours. High resolution measurements of chlorophyll a concentration at depth require the use of submersible in situ fluorometers. WebThe PAM-2500 chlorophyll fluorometer is an extremely compact and powerful measuring system. All optical and electronic components are located in a 23 cm x 10.5 cm x 10.5 cm housing. Different from previous portable PAM fluorometers, high-performance LEDs are employed for saturation pulses permitting quasi-rectangular light intensity changes.
