TAOMSUN 722G / 721G / 721 visible spectrophotometers feature a holographic blazed grating monochromator with high wavelength accuracy, excellent monochromaticity and low stray light. Backlit LCD display with microprocessor-based measurement system, auto 0% T / 100% T adjustment, concentration factor setting and direct concentration readout for simple operation and accurate readings. Automatic shutter technology protects the photodetector without a black body, extending service life. Standard 5 cm cuvette holder; optional serial printer and dedicated spectral analysis software. Wavelength range: 722G 325–1000 nm; 721G/721 340–1000 nm. Wavelength accuracy ±2 nm, stray light ≤0.1% T, photometric accuracy ±0.004 Abs (0–0.5 A). Suitable for scientific research, industrial testing, pharmaceuticals, food, water quality analysis, metallurgy, chemical industry and university education. Overseas sales / technical support provided by METICULAB (Korea).

Q: What is the difference between the 722G, 721G and 721?
A: The main difference is the wavelength range: 325–1000 nm for the 722G, and 340–1000 nm for the 721G / 721. The optical system and detector are otherwise the same.

Q: What is the lead time?
A: Usually 7–15 business days, which may be shortened depending on stock availability.

Q: Are the printer and analysis software available?
A: Yes. A serial printer and dedicated spectral analysis software are available as options.

Q: How is quality control carried out?
