The 752N UV visible spectrophotometer includes a holographic scintillation grating monochromator, with high wavelength accuracy and low stray light. It is equipped with a liquid crystal screen and a microcomputer system, with accurate T-A conversion and automatic adjustment of 0% T/100% T and concentration direct reading. Standard imported tungsten halogen lamp, deuterium lamp, and 1cm colorimetric dish holder, power supply AC220V 220V, power 120W. Wavelength 200~1000nm, wide photometric range, good accuracy and stability. Optional specialized software and customized colorimetric dish holder, suitable for various precise photometric analysis scenarios.

🔍 Core Features:Holographic blazed grating monochromator + imported photocell detector ensuring wavelength accuracy and reading precision; automatic light door technology protects the photoelectric sensor without requiring a black body; halogen tungsten lamp and long-life deuterium lamp (752G) ensure stable light source across UV-Vis range. Supports concentration direct reading, 30 concentration curve storage, and flexible cuvette configurations designed for research, industrial inspection, and production quality control.

Q: What is the difference between the 752G, 722G, and 721G?
A: The main difference is wavelength range. 752G is UV-Vis (200–1000nm), 722G is Visible (325–1000nm), and 721G is Visible (340–1000nm). Choose 752G if you need UV measurements; choose 722G or 721G for visible-light-only applications.

Q: What are the wavelength accuracy and repeatability?
A: Wavelength accuracy is ±2nm, and repeatability is ≤1nm across all three models.

Q: What is the photometric range and accuracy?
A: Photometric range is 0–100.0%T / 0–1.999A / 0–1999C, with accuracy of ±0.5%T, ±0.004Abs (0–0.5A), ±0.008Abs (0.5–1A).

Q: Does it support direct concentration reading?
A: Yes. Concentration factor can be set directly, and readings are displayed without additional calculation.

Q: What is the function of the automatic light door technology?
A: The automatic light door closes the optical path when not measuring, protecting the photoelectric sensor without requiring a black body, extending component lifespan and reducing maintenance costs.

Q: Can it accommodate other cuvette specifications?
A: Yes. The sample compartment accommodates 5–100mm cuvettes. The standard 1cm cuvette holder can be replaced with optional specifications.

Q: Is it suitable for export?
A: Yes. Export wooden case packaging, English manual, and 110V/220V customization are available. EXW / FOB / CIF terms are supported.

Q: What is the warranty?
A: One-year whole-machine warranty. Light sources and other consumable parts can be consulted for replacement.
