Application and feature:
Model WFZ-753 visible ultraviolet spectrometry meter is a microcomputer-based intelligent analyzer with excellent performance and novel structure. It has perfect data processing ability, can store 20 standard curves, and it is matched with multi-colour printer, which can directly print analysis result and draw standard curves at the same time. It can meet the needs of scientific research and production requirements in organic chemistry, biochemistry, medicine, environmental protection as well as various other fields. It is one of necessary instruments in modern analysis lab, especially suitable for quantitative analysis to various materials in chemical industry, metallurgy industry, foodstuff industry, pharmacy industry, clinic analysing and testing, environmental protection and other departments’ labs.
