The TAOMSUN 721 Visible Spectrophotometer uses microprocessor control technology to perform qualitative and quantitative analysis of substances in the visible spectrum (approximately 360 nm – 1000 nm), making it an essential multi-purpose analytical instrument for routine laboratories. The core optical system features a holographic blazed grating monochromator, delivering excellent wavelength accuracy, high monochromaticity and low stray light. Equipped with a backlit LCD display that eliminates the parallax and reading errors of pointer-type instruments, together with a microprocessor-based measurement system for high-precision T-A conversion, automatic zero/100% (T) adjustment and direct concentration readout. Built-in automatic light-shutter technology protects the photodetector without requiring black-body capping; paired with a high-performance tungsten halogen lamp, it ensures long-term stable operation. The instrument offers high reading accuracy, excellent reproducibility and good stability. It comes standard with a 5 cm cuvette holder, with a 10 cm cuvette holder and spectral analysis software available as options. It is widely used in physical and chemical testing, pharmaceutical testing, food testing, water quality analysis, environmental monitoring, and university teaching and research.
