Description
EziLab offers the Visible Spectrometer EZL-VS111, a single beam visible spectrophotometer that measures color and concentration across a 325 to 1000 nm wavelength range. It provides a practical, lower-cost alternative to UV-Vis instruments for labs that work only in the visible spectrum. A 2 nm bandwidth and 1200 lines/mm grating deliver ±2 nm wavelength accuracy with ≤1 nm repeatability, while photometric accuracy reaches ±0.5 %T with ≤0.2 %T repeatability and stray light stays at ≤0.1 %T at 360 nm. Readings cover 0 to 100% transmittance, 0 to 1.999 absorbance, and 0 to 1999 concentration, captured by a silicon photocell detector. Microcomputer control and automatic zero adjustment simplify routine daily operation, and four glass plus two quartz 1 cm cuvettes ship as standard, with an optional thermal printer and 50 mm cuvette holder. In industrial settings, food and beverage producers use this vis spectrophotometer for colorimetric testing and quality control of incoming and finished products. Chemical manufacturers run dye concentration analysis and raw material checks, while environmental laboratories measure visible-range parameters in field and process samples. Research and academic labs rely on it for biological analysis and teaching work. See the Visible Spectrophotometers and Visible Spectrometer EZL-VS111 pages for full specifications.
