Product Introduction
The 721 series visible spectrophotometer adopts a brand new design concept, draws on the strengths of various brands, has a modern appearance design, and outstanding data processing and control functions are the distinctive features of this instrument. Widely used in factories, mines, healthcare, schools, environmental protection, and research laboratories. Our goal is to provide high-quality analytical instruments for our customers.
Product features:
Adopting a self-aligning optical path design and a 1200/mm high-quality grating, it has the characteristics of low stray light and good monochromaticity.
The use of microcontrollers makes operation easier, and adjusting 0% T and 100% T only requires a gentle press.
Four measurement modes, T、A、C、 Slope method makes the operation more convenient.
31/2LCD LCD display is convenient for reading, and the large sample room can expand its functions.
721-100 can be equipped with a 100mm colorimetric dish rack, which is more suitable for content analysis in water plants and power plants.
