The process of photosynthesis is an important biological phenomenon that affects the life of all living creatures, and it is the main source of oxygen formation. Direct photosynthesis products are also used in the manufacture of other organic compounds involved in the formation of nucleic acids, fats, proteins, hormones, and others.
Dear Malinda Thilakarathna, Thank you for raising the question. I understood you are asking which type of photosynthesis measuring equipment to purchase. As to me I used the Infrared gas analyser (IRGA) for measuring the photosynthesis and related related performance mechanisms in plant leaf. Except its bulkiness (weight), the performance is very excellent.
You can use the following lik: http://14.139.58.69/icar_teldir/services/home/service_detail?name_instru=Infra%20red%20gas%20analyzers%20IRGA&unique_num=100&xdidz=252&p=../institute/instrument_image&d=services_inti&c=services_chargeinti&xdybz=institute_committee&qptsu=../institute/committee_image
Thanks everyone for your comments/reply. I am actually looking for an instrument to measure photosynthesis carbon assimilation efficiently with high precision. I found that there are many options available: LI-COR 6800, Walz GFS‑3000, PP Systems CIRAS‑3, ADC LC-Pro.
